单芯XLPE电力电缆负载试验与铠装结构选型

Simulated load test of single core XLPE power cable and selection of armour construction

通过非铠装、具有隔磁措施的钢丝铠装和全钢丝铠装单芯交联聚乙烯 (XL PE)绝缘电力电缆的模拟负载对比试验 ,证明单芯钢丝铠装电缆中的钢丝铠装结构 ,无论是否隔磁措施 ,都会产生大量的铠装损耗 ,大大降低电缆的载流量水平 ,严重时 ,可导致电缆热击穿。

Simulated load tests were conducted on single core XLPE power cables without armour, with wire armour with magnetic separation and with full wire armour. The result shows that the wire armour provided with magnetic separation or not may cause large armour loss. As a result, the current carrying capacity of the cable may be greatly reduced and the cable may breakdown in severe cases.
