各位:
目前MT818等标准中对半导电屏蔽料的要求不是很明确,比如半导电橡皮的体积电阻率应控制在什么范围内?普通高压电缆的交联聚乙烯为基料的屏蔽料可执行标准JB∕T 10738-2007 额定电压35kV及以下挤包绝缘电缆用半导电屏蔽料,请问橡皮为基料的该如何控制?还有就是在绝缘是乙丙的前提下基料是用天然橡胶好还是用乙丙的好?

胶料耐温等级应该匹配;

yuqk6878:
乙丙绝缘,最好用EVA做半导体
你用多少含量的EVA?

以前用的是天然丁苯的半导电,没用过乙丙的半导电胶,CPE半导电胶10KV以下用过,10KV 的没用过。
不过我听说有用过的,人家说效果还行,毕竟CPE的半导电胶成本低!
