Alloy Alloy Cable Cable Product Features

Materials and annealing process of the aluminum alloy conductor creep resistance alloy reduce the " creep " in the heat conductor and the tendency of pressure with respect to aluminum, the creep resistance by 300 %, to avoid the cold flow or creep due problems caused by relaxation . Tensile strength and elongation compared to the aluminum conductor aluminum conductor , due to join the special ingredients and the use of special processing technology , which greatly improves the tensile strength and elongation rate increased to 30% , the use of safer reliable. Thermal expansion coefficient Network Cabinet  Thermal expansion coefficient of variation is used to calculate the size of the material when the temperature changes . Copper-aluminum alloy with a thermal expansion coefficient equivalent years been reliably aluminum connector for copper and aluminum conductors , and most of the electrical connector in use today are made ​​of aluminum , which is particularly suitable for aluminum alloys. Therefore, the aluminum alloy conductor is connected exactly with the expansion and contraction. Electrical connection with the performance of aluminum alloy with copper conductors connected with the manufacture of the same security and stability. Aluminum components significantly improve the performance of their connection , when the conductor annealing , add iron to produce high strength creep resistance , even in the long overload and overheating , but also to ensure that the connection is stable. Weight bearing capacity of high strength aluminum alloy improves the tensile strength of aluminum , aluminum cable can support the weight of 4000 m length of copper cable can only support 2,750 meters . This advantage in large -span buildings ( such as sports stadiums ) wiring reflected particularly prominent. Anti-corrosion layer of aluminum oxide thin sturdy inherent corrosion resistance when the edge is formed from the aluminum surface in contact with the air , the oxide layer is especially tolerant of various forms of corrosion . And alloys of rare earth elements can be added to further improve the corrosion resistance of aluminum alloys , in particular electrochemical etching . Features aluminum can withstand the harsh environment so as to be widely used in conductor cable tray , and many industrial components and containers. Usually associated with the generation of corrosion of dissimilar metals connected in a humid environment is related to the use of appropriate protective measures to prevent the occurrence of corrosion , such as the use of lubricants , antioxidants and protective coatings . Acidic soil environment and certain types of alkaline soils have more corrosive to aluminum , so direct burial aluminum conductor insulation should be used to prevent corrosion or molded sheath . Sulfur-containing environments, such as railway tunnels and the like where the corrosion resistance of the aluminum alloy can be significantly better than copper. Flexible aluminum alloy VGA CABLE  has good bending properties , its unique alloy formula , processing technology, greatly improved flexibility . 30% higher than copper, aluminum flexibility, rebound 40% lower than copper. Usually copper bending radius of 10 to 20 times the outside diameter , and the aluminum cable bend radius is only 7 times the outside diameter , terminal easier . Common characteristics of domestic armored armored cable , they use steel tape armored , low security level , when subjected to external destructive , their resilience is poor, prone to breakdown , and the heavy weight , the installation cost is quite high , coupled with corrosion-resistant performance is poor, life is not long . And we developed according to the American standard metal chain armored cables , aluminum is used with a chain armor , chain structure between its layers , to ensure that the cable can withstand strong external destructive , even if subjected to greater pressure cable and impact , the cable nor easily breakdown, improved safety performance. While the structure of the cable armor and the outside world, even in case of fire , armored cable increases the level of fire retardant reduces fire risk coefficient . Armored aluminum structure with respect to the steel tape armored , its light weight , convenient laying , bridge -free installation , can be reduced by 20 % to 40 % of the installation costs. According to different places you can choose different outer jacket layer, so that the use of armored cable is more extensive. Pressed from a single volume conductivity characteristics considerations, aluminum is less than copper , but we have developed not only made ​​from conductive material performance improvements , and in the process has also made a major breakthrough , we use unconventional pressed technology, pressed coefficient of 0.93 , while squeezing coefficient shaped line can reach 0.95 , first of its kind in the country . By squeezing the maximum limit , you can make up for deficiencies in the bulk conductivity of aluminum alloy , so truthfully stranded conductor wire core center conductor in general, significantly reduced core diameter, to improve conductivity, in the case of equal ampacity conductor outside Drive only 10% larger than the copper .
