1, cable carrying capacity
Aluminum alloy resistivity between aluminum and copper, slightly higher than aluminum, and lower than copper, in the same cut-off capacity under the premise of the same length of aluminum alloy conductor only half the weight of copper. Thus, when the alloy conductor has a cross-sectional area of 1.5 times that of copper, its electrical properties are the same, that is, the same cutoff, resistance, and voltage loss as copper are achieved.
2, to reduce the cable cross section
Aluminum alloy cable production process, Germany's most advanced compression technology, so that the conductor's fill factor can reach 93%. And aluminum alloy cable is used in silane cross-linked polyethylene, this insulation only 2/3 of the thickness of PVC can be far more than the conventional insulation performance. While the copper filling factor is generally only 80%, commonly used insulation is the use of PVC, so the aluminum alloy cable diameter only on the basis of copper increased by 11% or less, you can have the same copper electrical performance. It can be seen that the use of aluminum alloy cable without changing the original use of copper cable pipe design.
