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.

5.Applications
1.Power Industry
Aluminum cables are widely used in transmission lines, substation contact lines, power distribution systems and other fields to ensure the stability and reliability of power transmission.
2.New Energy Development
Aluminum alloy cables support the large-scale transmission of new energy sources such as solar and wind energy, providing a reliable means of power transmission for the development and utilization of clean energy.
At the same time, aluminum alloy cables have good recyclability and reusability, in line with the requirements of sustainable development.
3.Industrial production
In factories, mines, manufacturing and other places, aluminum alloy cables are used for the electrical connection of various equipments and machines, adapting to high temperature, high humidity and other harsh working environments.
4.Transportation
Aluminum alloy cables can be used for the power supply of rail transportation systems such as subways and streetcars, as well as the power transmission of electric vehicle charging piles, supporting the sustainable development of urban transportation.
5.Residential and Commercial Buildings
Aluminum alloy cables are used to connect power supply, lighting, air-conditioning and other electrical equipment in residential and commercial buildings, hospitals, schools, libraries and other public facilities, reducing construction costs and ensuring electrical safety.
6.Special Occasions
In high-rise buildings, ancient buildings, military bases, aerospace and other special occasions, aluminum alloy cable’s lightweight and high-strength characteristics make it an ideal choice for electrical wiring.
6.Working temperature and laying conditions
a) Power frequency rated voltage U0/U 0.6/1kV.
b) The allowable long-term maximum temperature of the cable conductor does not exceed 90°C.
c) The maximum temperature of the cable conductor does not exceed 250℃ during short circuit (the longest time does not exceed 5S).
*Laying on the ground
d) The ambient temperature during cable laying shall not be lower than 0℃.
e) The bending radius of the cable is:
Single core cable: 20D
