　　使用特性

　　SERVICE CHARACTERISTICS

　　電纜導體的額定溫度為90℃,短路時(最長持續時間不超過5S),電纜導體的溫度不超過250℃。

　　敷設電纜時的環境溫度應不低于0℃,低于0℃時應先預熱。

　　敷設電纜時允許彎曲半徑:單芯電纜不小于電纜外徑20倍;多芯電纜不小于電纜外徑的15倍。

　　Rate voltage max is 90℃.at short circuit (duration max ≤5S) ,temperature max is not higher than 250℃.

　　The temperature of laying should not be lower than 0℃ , pre-heating is needed if the ambient temp.of laying is lower thano℃.

　　The bend radius for laying: the one of single core cable shouldnot be shorter than twenty times of outer diam; the one of mu-lti core should not be shorter than fifteen times of outer diam.
