Storage method of cable

Cable if stored for a long time, according to the position of the cable, should make the following considerations:
1, under the eaves. Barrier Terminal Block only in not exposed to direct sunlight or ultra high temperature, standard LAN cables can be applied, recommend the use of pipeline.
2, external wall. Avoid direct sunlight and man-made damage to the wall.
3, in the pipeline (plastic or metal). As in the pipe, pay attention to thermal damage and metal pipe plastic pipe.
4, application of suspension / overhead cable. Considering the cable sag and the pressure, to adopt what kind of binding mode, cable is directly illuminated by the sun.
5, directly in the underground cable trench laying, the environment is the control of the minimum range. Cable trench installation must be periodically dry or moist degree examination.
6, the underground pipeline. In order to facilitate future upgrades, replacement of
Plug-In Terminal Block 
, and surface pressure and the surrounding environment isolation, auxiliary pipe isolation, auxiliary pipeline is a better method. But don't expect the pipeline will always keep dry, it will impact on the cable type selection.

Protection measures of cable

With the rapid development of power cables buried underground engineering, a higher demand on the protection of cables, cable protection sleeve is the use ofpolyethylene PE and high quality steel tube after sand blasting pretreatment, dipcoating, heating and solidifying process produced. It is the protection of wire and cable, a kind of the most commonly used electrical insulating tube. Because it hasgood insulation properties, high chemical stability, no rust, no aging, can adapt to theharsh environment and widely applied.
Use the Fiber Optical Patch Cord protection sleeve protecting cat6 network cable can achieve the followingadvantages: 1, good corrosion resistance, long service life, can be in moist saline alkali area. 2, flame retardant, good heat resistance, can be used in high temperature of 130 degrees and long term deformation, fire is not burning. 3, high strength, high rigidity. In under the road buried without a protective layer of concrete, can roll fastcable engineering construction schedule. 4, cat5e network PCB Spring Terminal Block protection sleeve for pipe or pipehas a certain flexibility, can resist the external stress and foundation settlementcaused by the destruction of the. 5, has good performance of anti interference signals. 6, smooth inner wall, do not scratch the cable. The design adopts a socketconnection, convenient installation and connection. The joints with rubber sealing ringseal can adapt to the thermal expansion and contraction, and to prevent sand entering.

How to properly use the patch panel?

Living room with a patch panel Living room Electric Category: Electric is the main living room TV and peripheral equipment, audio and video enthusiasts will configure some special surround sound system. In addition, like the telephone, the communication device is a router which is the most common devices seating. voice patch panel living room electrical characteristics: Electric high-value, use a long time, the use of high frequency, high power supply quality requirements; phones, cats, routing and other equipment also requires a lightning protection function. Study with the cat6 patch panell study Electrical category: Electrical within general study are relatively simple, common computer, small size TV or desktop speaker system and so on. The study of electrical characteristics: frequency of use is not necessarily high, electric power is not great. Designed for computer application design: a separate host and three peripheral power jack socket; Alloy shell with environmentally friendly flame retardant engineering plastics, flame retardant, excellent impact resistance, moisture barrier, heat capacity; Built-in lightning protection circuit; Bedroom recommended patch panel Bedroom Electric Type: Common appliances in the bedroom with air conditioning, electric heating, TV. Bedroom electrical characteristics: Most appliances in the bedroom at night use, each use is not a short time. While at night the city power grid load is low, some cities there are nighttime preferential tariff halved, you can take advantage of. Child protection door, you can also prevent foreign matter into smaller wiring board;
