     聚乙烯是目前应用最广、用量的塑料,从表中数据看出,聚乙烯的介子损耗小,电阻率高、击穿场强高,耐候性、工艺性好,是目前的电绝缘材料。但由于其工作温度低,所以主要用作通信电缆500万彩票的绝缘。中密度和高密度聚乙烯的强度和硬度较高,其透水率低,多用作电缆护套。但是,聚乙烯有的缺点,即容易燃烧,且黑烟浓烈,因此它的应用给环境带来了许多隐患。


     交联聚乙烯是利用低密度聚乙烯加入交联剂而形成的一种优良的热固型绝缘材料。它在继承聚乙烯诸多优良性能的基础上,提高了力学性能,耐候性和允许工作温度,从而成了目前电力电缆的绝缘材料。

     由于加入交联剂不同,所以形成了不同的交联工艺。目前用得最多的化学交联、温水交联、和辐照交联三种。化学交联主要用于中高压电缆(如10KV及以上);温水交联和辐照交联主要用于低压电缆(1kV及以下)。
