In engineering applications, an important criterion to judge whether aluminum cable and other cable products are suitable cable ampacity. The reason why copper cable is widely used, it is safe carrying capacity of copper wire 5 ~ 8A / mm2 conductor than aluminum higher conductivity and safety can be adequately protected. 

 

      For over-reliance on copper cables, a direct result of copper wire and cable industry to China accounted for more than 60% by volume of copper, 70% from foreign imports, raw materials supply, the price is high since each line will cause fluctuations in copper prices cable industry shock.
