The electrical property of flame-retardant engineering plastics, especially comparative tracking index (CTI) is described.
这对阻燃型工程塑料的电性能，尤其是比较跟踪指数（CTI）进行了描述。

This sheath can be either conventional PE or a special anti-tracking sheath if the cable is likely to be subjected to high electrical field strengths.
最后挤外护套，采用常规的聚乙烯或一种特殊的能承受高电场的耐电痕聚乙烯。
