Aluminum alloy conductors originated in North America and have been widely used as cable conductor materials since the 1970s. Aluminum alloy conductor cables have been widely used in residential, commercial, industrial and military projects due to their advantages of safety, reliability, stable operation, and high cost performance. At present, more than 80% of low-voltage product applications in Europe and the United States are aluminum alloy conductor cables, and 40% of medium-voltage cable products are aluminum alloy conductor cables.
1)The long-time working temperature of cable should not be higher than 70℃. 2)When core is in short-circrit (max 5s)the temperature should not excced 160℃.
Bending radius of single core cable is 20(d+D)±5%Bending radius ofmulti-core cable is 15(d+D)±5%D=Aetual outer diameter of cable sample(mm)d=Aetual diameter of the comductor(mm)
