磁性不锈钢丝编织铠装损耗的实验研究

Experimental Study on the Loss of the Armour Consisting of Magnetic Stainless Steel Braid

本文介绍了上海电缆研究所对单芯交联聚乙烯电力电缆的磁性不锈钢丝编织铠装损耗开展的实验研究和理论计算 ,证明磁性不锈钢丝编织铠装的损耗可达铜损耗的 1 .9倍 ,降低了电缆允许的载流量。

This paper presents the experimental study on and theoretic calulation of the loss of the armour consisting of magnetic stainless steel braid used in a single core XLPE power cable. It demonstrates that the loss of magnetic stainless steel may be as high as 1.9 times that of copper, resulting in decrease in the permissible ampacity of the cable. Our experimental study provides the base for engineering application.
