1. What insulation material is used for aluminum alloy cable?
Aluminum alloy cable insulation material has two kinds of conventional, cross-linked polyethylene and polyvinyl chloride, cross-linked polyethylene is better than polyvinyl chloride, its electrical properties, heat resistance, physical and mechanical properties and toxicity than PVC, At present, all aluminum alloy cables use cross-linked polyethylene insulation.
2. Why is there less aluminum alloy cable below 10mm2?
Aluminum alloy cable connectors require copper-aluminum transition terminals, and terminal connections are generally not required for cable installation under 10 square meters.
3. What are the advantages of aluminum alloy cable and copper core cable?
The advantages of the aluminum alloy cable in comparison with the copper core cable are: good bending performance, strong corrosion resistance, low resilience, light weight, and low bridge cost.
4. What is less than aluminum alloy cable copper core cable?
As the aluminum alloy cable is slightly less conductive than the copper cable, the conductor cross-section is 1.5 times that of the copper cable at the same current carrying capacity. This is the main difference, but this will not affect the use, because it is the connection of the device or the cable. The layout, this difference in size is within the allowable range, will not cause the use of the impact, unless there are special occasions, it is not suitable to use aluminum alloy cable instead.
5. Will the increase in aluminum alloy cable size lead to increased cost of the bridge?
Since the use of aluminum alloy cables instead of copper cables will increase several to ten or more millimeters, many customers are worried that they will increase the problem of the bridge. The answer is certainly not, because when the cable tray is designed, there is a certain distance between the cables, leaving a certain margin, this is for the cable cooling needs, so using aluminum alloy cable even if more than a dozen millimeters will not lead to The increase in cable trays actually saves bridges, because the same current capacity, the same length of aluminum alloy cable is only half the weight of copper cables, so the distance between the cable trays is longer, the number of trays will only decrease and will not increase, for a few The number of cables can be removed from the bridge and fixed directly with cable clamps. The installation cost will be greatly reduced.
6. Why should we promote aluminum alloy cable, which is it in line with what economic development?
The aluminum alloy cable conforms to the three economic development situations in China. First, it conforms to the Outline of China's Twelfth Five-Year Plan and focuses on the development of new materials and new energy industries and industrial policies. Second, it conforms to the central government's principle of building a conservation-minded society and a conservation-minded country. Third, it meets the specific goals and requirements of the State Council's guidelines on energy conservation and emission reduction.
7. Why is the price of aluminum alloy cable significantly higher than aluminum core cable?
Aluminum alloy cable adds copper, iron, magnesium, rare earth and other alloy elements to electrical aluminum, and through process adjustment, the mechanical properties of the aluminum alloy conductor are greatly improved, and the pure aluminum conductor is prevented from having low elongation and poor creep resistance. The problem of poor flexibility increases the connection reliability of the cable system. The process is much more complicated than the electrical aluminum pole and the requirements are high. Therefore, the price of the aluminum alloy cable is higher than that of the aluminum core cable.
