硅烷交联聚乙烯电缆在交联过程中铜线芯变色的研究

Study on the Discolouration of Copper Core during the Crosslinking Process of Silane Crosslinking PE Cable

研究了硅烷交联聚乙烯电缆在交联过程中铜线芯变色的原因,并通过在硅烷交联聚乙烯电缆料中添加助剂来纯化铜的活性,防止铜与其它物质发生反应。

The causes of discolouration of the copper core of silane cross linked polyethylene cable during the process of cross linking were studied.By means of the aids,the activity of copper was reduced,the reactions between copper and the other materials were avoided,so corrosion discolouration of copper was restrained during the process of cross linking.
