the development of some of the problems vga cable

In recent years, China's wire and cable industry to flourish and made remarkable achievements, but compared with their foreign counterparts still in the emerging, low level of technology status, independent innovation ability, the product structure is irrational, affordable products  WISDON 90 degree hdmi cable overproduction , and high-tech, low proportion of high value-added products production, industry chain is not perfect. In this regard, the industry's appeal should strengthen supervision and standardize the development of wire and cable industry.
"At present, the domestic wire vga cable market, prices of many small and medium enterprises to become competitive weapon. Due to the wire and cable materials are typically heavy, light engineering industry, the  mini usb cable price of raw materials accounted for 70% to 80% of the cost, therefore, the pros and cons of raw materials largely affect the quality of wire and cable products, according to statistics, China's cable manufacturing enterprises reached 7000, but the scale cable companies much more of a small business, the production of wire and cable industry concentration low, the biggest share of the enterprise market, but also in the amount of 1% to 2.5%. currently on the national wire and cable market, shoddy, fake, defective products is very serious, and rj45 modular jack  even some "free product" there are quality case of non-compliance. Additionally, the industry regulator there "just punishment regardless of" phenomenon, this situation has also led to the wire and cable industry difficult. Currently, the domestic market wire and cable management is very confusing, in this circle there is an unwritten rule Even some of the manufacturers of quality from regular cable to the middlemen will become the "three noes" products.

Control VGA CABLE industry overall good technical quality

 At present, the higher the gold content of domestic cable companies have relatively few patents, utility model patents more; may often multinational patents are generally patents, we can see the gap between domestic companies and multinational corporations lies.
    Meanwhile, combine patented technology and production, improve the conversion rate of patent achievements, patented technology  terminal block ultimately translate into productivity, effectively enhance the competitiveness of enterprises. Combination of qualified personnel and enhance the development of wire and cable business, science and technology is to support, talent is the key to strengthen the innovation of personnel. Only science and technology as the core driving force and an important starting point in order to effectively change the mode of economic development, to win the future development of the initiative, if technological innovation is the development of life, then the talent is the driving force of technological innovation.
    Currently, VGA CABLE industry overall WISDOM sfp connector  good technical quality, integrated talent scarcity. The reason is that many companies have wanted to bring talent comes in handy, but rarely pay attention to the cultivation of talent, the brain drain has seriously affected the wire and cable industry into the international market pace. For who just graduated from college cable professional theoretical knowledge they learned really a lot more than the actual result of the contact, after entering the plant, when to deal with practical problems often seem confused, powerless, a lot of error analysis and judgment, perhaps to the company artificially caused some loss, this time to feel limited company this person is not strong level, no  hdmi switch longer give him room for improvement, no longer object to let go as a culture in important positions, and very conducive to the growth of talent, and some technical personnel the ability to get free play in the post, leading to interfere too much, technological innovation, enthusiasm and creativity significantly weakened, industry like many such cases.

difference vga cable and ordinary wire structure

Wires for carrying electric current conductive metal wire. There ﹑ stranded solid braided or foil and other forms. Divided by the insulation condition bare wires and insulated wires into two WISDOM rca audio cable  categories. Cables insulated from the one or more mutually insulated conductive wire cores placed in the sealed configuration of the sheath. An outer protective cover layer may be added, that the difference between the wire and cable wire size is generally small, the structure is simple, but the cable may also be included in the sequence of generalized wires.
  Power cables and wires of common difference is mainly the larger cable size, the  WISDOM micro usb connector structure is more complex. Cable mainly consists of the following four parts group. Flex Heart: with high conductivity material. Insulation layer: as the cable insulation material should have a high insulation resistance, high breakdown electric field strength. Often the cable insulation material classification.
 In addition to the above differences, the cable also has a distinct advantage. Compared with overhead lines, the advantage is that the cable insulation distance between lines of small, small footprint, without WISDOM rca video cable  accounting for the laying of underground space above ground, the impact of environmental pollution from the surrounding, power transmission and high reliability, safety and the environment for interference small. Thus, cable and more used in densely populated areas and dense grid congestion and busy place. For modernization have a negligible effect.

Power vga cable some planning

In this regard, we are far and abroad compared to the lack of forward-thinking. Another story makes the network a few years ago widespread lament: Sewer Qingdao former German leased area  WISDOM hdmi wall plate after the efficient use of over a hundred years, some of the parts need to be replaced, but when companies are long gone. Later, a German company sent e-mail, said that under the construction standards of German companies in the range of 3 meters surrounding the aging parts, spare parts can be found in a small storage warehouse. Urban Construction Company pursuant found in the sewer of a small warehouse, which are all good spare parts oil cloth, still bright as new.
  Built centuries before German sewers, underground Qingdao still be WISDOM cat6 patch panel  effective; 10 years ago, we laid underground cable, why even accurate positioning are struggling? A city Shimoji cables, water pipes, gas lines, although always "not see the light," but it is the city's central nervous system and capillaries. Drawing hard to find underground cables, a reflection of our building, the absence of regulation in some.
   Sewer and underground cables, is people's livelihood, public buildings and facilities, and embodies the city's "quality" and "conscience." Government departments and facilities construction unit, construction should own all the products to establish a complete file, and regular checks and maintenance.
  Only then, when the facility "pull Abduction" in order to immediate  WISDOM usb connector repairs to avoid a big impact to the public life. Only in this way, the pace of development of our city, it will not be tripped over a power cable.

China wire vga cable specialty cable market acceptance for open attitude

With the recent global wire and cable market matures, showing the WISDOM rj45 keystone jack  development of wire and cable manufacturing slowdown, the growth rate is not the situation. The impact of changes in the external environment and internal competition, making the world's wire and cable industry into several giant monopolistic competitive landscape. However, almost all concentrated in low areas on low prices to grab market in recent years due to price of copper, aluminum and other raw materials, rising cable profits diluted, business survival difficult, unable to upgrade, which became the bottleneck in the development of domestic enterprises. Currently in profit margins of high-end specialty cable areas, the  WISDOM scart splitter Chinese market is completely cross-border wire and cable giant to seize the Chinese market acceptance of special cables for open attitude for a long time to get out of the way to provide a scuffle in the low-end domestic cable companies, and like spring blowing head for China wire and cable industry this "dying patient" injected a shot in the arm. About According to statistics, China's cable special cable market accounted for 30% of total sales, about 400 billion yuan. Specialty cable market demand just as a huge fine but divided the stage, local businesses need to grasp, to develop, to the occupation. Because of special cables in the power, nuclear power, shipbuilding, port machinery, locomotives, rail transportation, tunneling, mining and exploration, land and WISDOM dvi to hdmi adapter  sea petroleum engineering, aerospace and other fields has been widely used, and therefore the development of high-end specialty cable has a broad prospects for development. This brings new market opportunities for domestic photovoltaic cable companies have a certain strength. Expect a veritable industry emerged in a number of high-tech wire and cable business.

Extensive use mine vga cable

A considerable proportion in the national economy, large wide product categories, as has been widely used in mining cable facility economies that are used in the operation, equipment and apparatus, especially the WISDOM rj11 socket  huge power transmission systems and information delivery systems, and services in all social activities and reaching out to every family and individual's daily life, and therefore mine cable products have reached everywhere in the state. And still with the socio-economic activities carried out step-jump from the depth to develop breadth; coupled with people's standard of living and quality of life is ever increasing, continues to promote the development and production of mining variety of cable products increased. Therefore, in the mid-1990s, a futurist had predicted: twenty-first century will be a line (mine cable) in the WISDOM telephone connector  world. Thus in this industry has always put mine cables for power systems than as human vascular; the electromagnetic transmission of information using mine cable compared to the body's nervous; would be made electrical, instrumentation winding wire used as the heart than important components. Mine cable in order to illustrate the indispensable nature in all economic activities and social life.

The main purpose vga cable laying

When laying power cables must first be straightened, and then securely  WISDOM rca video cable fixed to the wall or flat. After doing should be neat, attractive, fixed spacing shall comply with the requirements. Encounter bend the cable bend radius should meet the requirements, in the elbow were applied on both sides of the cable clamps 100mm fixed.
At the same time a variety of cable laying, cable bending radius according to the maximum diameter of the cable bend radius bend, neatly laid.  Along the stent card set
When the cable to the bracket card set, requires each stent has cable clamps to secure it. Fixing angle brackets should be considered in some cases fire rating.
When the power cable laying lines in case the river, such as water, power cables can WISDOM 1394 cable  be laid under the water, in order to achieve the purpose of crossing the river, the lake. When laying cables, construction should be strictly in accordance with the requirements of the operating specifications to meet the requirements of national acceptance and economic, practical and beautiful. Intermediate power cable accessories for the intermediate cable connections should be used in accordance with its specifications used in power cable specifications. A middle line there are several sets of intermediate connectors you need to connect accessories. Terminal accessory for connecting the two ends of the line, fixed, its specifications should be selected according to the specifications of the power cable used. Each line requires two sets of terminal attachments. Sealing WISDOM hdmi switch  insulation accessories for power cables Cable Joints and terminal head sealing and insulation. The number of matching supply by the cable provider.

WISDOM hdmi extension cable MDF uses

MDF is positioned in front of the central office of information points modular device management. The front of the information point cable ( Cat5e or 6 cable ) into the equipment room after the first into patch panels, patch panels will hit the line modules , patch panels and switches then connect a jumper (RJ45 interface) . Overall, the patch panel is used crossover ethernet cable to manage the device , for example, if there is no patch , direct access to the front of the information points to the switch , so that once the cable problems, faced to rewiring. In addition, the management is also a bit confusing, multiple plug may cause damage to the switch port. MDF exist to solve this problem by replacing the jumper to achieve better management.Dosage and overall network is mainly based on the number of points or the floor ( and similar floor , depending on how the system is designed diagram ) points to the number of network configurations . Different buildings , different system designs , patch panels are the main differences between the devices . For example, a building only four rooms , the master device is set on the first displayport to hdmi cable floor , all floors between network points are entering the device , then the patch is equal to the number of the building all network points / patch panel port number ( 24 mouth, 48 , etc. ) , plus got to margin ; If, on the 9th floor of a building has a room , the master device is set on the fourth floor , then in order to avoid long cable , it may partakers devices are located on each floor , and there is exchange equipment . So the main distribution frame between devices on the network is equal to the number of points / patch panel ports ( 24 , 48 , etc. ) 4 layers.

Currently WISDOM vga cable we are using the Ethernet cable is the most widely used twisted pair

Is composed of four pairs of twisted wires 8 different color composition, woven together into one every two pairs;rj45 modular jack Here I will not discuss specific steps to create a network cable, just simply say what a standard Ethernet cable wiring, because in reality, people often asked: "? the use straight-through cable or crossover cable" There are two methods to connect the twisted pair, respectively, and a hdmi extension cable straight-through cable crossover cable; their wiring there are two ways: T568A standard or T568B standard, the following were said about these two wiring standard line sequence.

The key performance vga cable

Prefabricated branch cable and other cable products, is in the range of factory production equipment, which will be produced in assembly line of cable products. A good quality prefabricated branch cable, must WISDOM HDMI CABLE  be excellent performance of mining cables, because the performance of the cable is the basis of indicators of prefabricated branch cable products. For domestic product, its conductor, insulation performance, mechanical and physical properties of materials shall comply with the relevant national standards. Prefabricated branch cable quality measure factors including the main branch cable type, size, cross-section, length and branch locations and other WISDOM Displayport CABLE  indicators. Shanghai People's cable to bring you a detailed description of factors.
A branch connection body
   Critical to the performance of the branch connection body, which is the key performance prefabricated branch cable. Branch joins the main body of the cable and the branch cable conductor connected as a whole, and for insulation moisture treatment. Decided to branch connection body lies in material and workmanship, performance-critical branch joins the body, the majority of designers, the cable should be fully concerned with the quality of prefabricated WISDOM VGA CABLE  branch cable, choice of materials and production processes joints, tooling.
2, prefabricated branch cable resistance
  Contact resistance requirements and other branch cable length ratio of the reference resistor R1/R2 ≤ 1.2; when the main cable and the branch cable, respectively, by the rated current, heating for 5 hours, cooled 3 hours as one cycle, 25 cycles after the coupling the surface temperature does not exceed 75 ℃, after each cycle, the surface temperature of the joint surface temperature not higher than the first 25 cycles 8 ℃.

Some of the different characteristics vga cable

This is really quite incredible, but also proves that China 's wire and cable industry has been derived from the confusion within the industry to "foreign trade" , extending from the external publicity and marketing. And now, the government has introduced a certain ranking is a lack of authoritative business , but more interesting is that when the wire and cable WISDOM RAC CABLE manufacturers in the number of qualified applicants bid on the table , asked  to fill out impressively display the " enterprise in the industry Rank "or" enterprise market share in the industry "requirement . From the perspective of the relevant government departments, doing nothing wrong , was simply trying to understand the size of the business and marketing capabilities , but ignored the lack of such specialized rating agencies . The companies are often faced with such requirements have been caught unprepared , do not know how to fill .
Because of this , some companies have chosen to leave newspaper rankings, ranking greatly to his premise . There are only a few hundred or even a total number of employees, sales of less than $ 1 billion business , even in the " business in the country's market share" column, immodestly fill 3% , and this turned out to fill passed, ironic .
Some aspects of the lack of industry rankings , and  WISDOM Network Cabinet very worthy of attention each wire and cable manufacturers , such as , for now, the wire and cable industry to date, the lack of official ranking list released by the industry , whether it is the wire and cable industry associations, or local the wire and cable industry associations, have not done an accurate , authoritative , formal corporate rankings. But from the " qualified bid " process, we found that business was asked to fill in the rankings , scrambling to get business know what to do . We can not help thinking, maybe because when asked to fill out an application companies ranked qualifications , will lead to a variety of ranking on the Internet , including some of the manufacturer or small groups themselves casually fabricated wire and cable rankings, and  WISDOM VGA CABLE even their own businesses is negligible micro-enterprises , also among the prominent .
Such ranking is undoubtedly the lack of credibility , even those who have never heard of the cable companies ranked in the top ten or even the first business, and like those brilliant performance , the industry's well-known companies are ranked in more than 70 after that, not even a single rank of such a phenomenon can only be explained confusion wire and cable industry , has been constantly farce .

vga extension cable prominent role in social development

In modern society, there are people who live in places where there is production, transportation, and all economic activities of the occasion, where in space, ground, ocean and all need to explore and develop all of the activities, as well as any one technological development and innovation Development activities in the project, are inseparable from power and WISDOM fiber optic cable  electromagnetic applications. The occurrence, transmission and application of electrical and electromagnetic waves are mine cable must be used as a connection, transmission parts or as a winding material host. In fact, all industrial production, transportation, construction and facilities, modern agriculture and scientific research, military equipment or military facilities, space, ocean detection and social life and mine cable products are closely related.
 A considerable proportion in the national  WISDOM VGA CABLE economy, large wide product categories, as has been widely used in mining cable facility economies that are used in the operation, equipment and apparatus, especially the huge power transmission systems and information delivery systems, and services in all social activities and reaching out to every family and individual's daily life, and therefore mine cable products have reached everywhere in the state. And still with the socio-economic activities carried out step-jump from the depth to develop breadth; coupled with people's standard of living and quality of life is ever increasing, continues to promote the development and production of mining variety of cable products increased.

From the extension cable production equipment to see product features

 Vehicle line is a large division of the cable industry application category, the most important application areas of automotive and WISDOM Network Cabinet  other transportation vehicles. So there are different cables and general love of product characteristics on application requirements. When it comes to product features, summarizes the angle is large, the people of Shanghai Cable lead us today from the perspective of cable manufacturing equipment to study his product characteristics.
   Automotive production equipment line is mainly extrusion equipment, also known as extruders, extrusion materials, ease of molding also plays an extremely important role, so the rational use of the screw structure and parameters are to get a good quality of products and an important part of production.
   To meet the needs of different processing, there  WISDOM Terminal BLOCK are many types of the screw, the main types of the physical properties of the selection of raw materials and production technologies to determine the specifications of the extruder.
1, on a small extruder used is a full thread depth ranging isometric type, the smaller aspect ratio of the screw is mainly used for a small section of the extruded insulation and sheath layers, the extrusion speed.
2 medium-sized screw thread depth gradient using isometric and full thread type, so the extrusion amount more, and do not affect the strength of the screw extrusion speed.
3, large screw diameter of 150mm or more generally, mainly for wire and cable insulation and sheathing layer produce large cross-section.
   Car manufacturers often use the line according to their main product categories to choose extrusion equipment, the WISDOM VGA CABLE  same, different extruded cable extrusion equipment product specifications, characteristics, applications will also be a greater difference.

The use of high-pressure vga cable issues to be aware

 Why insulation standards will appear in the discharge phenomenon? We electromagnetic theory, we can see three core cable distributed capacitance three phase, is surrounded by the shield contact, there  WISDOM mini usb cable is no external electric field, there is only the electric field. Energy transfer can only be carried out in-house, will not be disclosed. Unshielded high-voltage insulated wire distributed capacitance is more complex, but from the recent grounding wire capacitance largest body most likely to produce a discharge. Always encounter the need for short cables single cable. Electrical engineering installation, sometimes with three core high voltage cable, stripped the skin, and then stripped ladle armor, take three cores for single-core cables. Even WISDOM hdmi wall plate  single-core cable insulation resistance World to meet the requirements, if installed from outside the core metal components close, will also appear on the structure discharge phenomena, wet weather in the spring is more obvious, this phenomenon would endanger equipment and personal safety.

How electricity hdmi extension cable industry to meet the challenges

 Development of the power cable industry, in recent years, infrastructure has been considerable progress, but this year, rising material costs and allows the power cable industry welcomed the challenge of  WISDOM utp cable China's power cable industry is second only to the automotive industry big industry in recent years, consumption of copper, 60% -86% of total domestic copper consumption, already is a major demand for refined copper channels; Therefore, development of wire and cable industry will directly affect the domestic demand for refined copper and the ultimate impact of copper prices. At present, China's small and medium enterprises reached more than 7000 power cable, the number is incomparable to any one country, but the concentration is low.
  Many enterprises, a direct consequence of industrial concentration is low industry margins, excess capacity, making the huge Chinese  WISDOM mini usb cable power cable industry seems to be rather confusing. The current weakness in the global economy as a whole, the recovery process is slow; exciting "Chinese demand" delays in the release of the economic winds gradually penetrate the downstream copper related industries in China. The substantial expansion of Chinese power cable industry mainly due to early government support for real estate, electricity, electronics and other industries, in the current policies continued access sluggish, combined with the power cable industry WISDOM hdmi wall plate  is not high quality, technical content and poor The combined effect, resulting in a further decline in demand for power cables, orders dropped severely.
  China power cable industry, while having a leading worldwide production capacity, but there is a more serious product structure is irrational enterprise mainly produces low-value low-voltage power cable, and high-pressure, high pressure, such as high-end products are dependent on imported power cables .
