Product Description

Product Instruction

Aluminum aloy power cable makes up for the shortcomings of pure aluminum cable in the past, although it does not improve the electril.cal conductivity of the cable, but the bending performance, creep resistance and corrosion resistance are areaty improved, which can ensurethat the cable maintains continuous performance and stability when overloaded and overheated for a long time.

2.Standard

GB/T31840:1 ~ 3 ~ 2015 Rated voltage: 1kV(Um=1.2kV) to 35kV(Um=40kv) aluminum alloy extruded insulated power cable

3.Performance Characteristics

（1）Conductivity: The conductivity of aluminum alloy is about 61.8% of that of copper, and the current-carrying capacity is 79% of that of copper, which is better than the pure aluminum standard.

（2）Weight Advantage: Aluminum alloy cables are about half the weight of copper cables, making them easy to install and maintain and reducing installation costs.

（3）Mechanical properties: aluminum alloy cables have excellent creep resistance, tensile strength and elongation, as well as good flexibility.

（4）Corrosion resistance: Aluminum alloy cable can form an oxide layer on the surface, and the addition of rare earth elements can further improve the corrosion resistance, especially suitable for harsh environments.

（5）Coefficient of thermal expansion: The coefficient of thermal expansion of aluminum alloy is comparable to that of copper, making it suitable for use with copper conductor connectors.
