　　使用特性

　　SERVICE CHARACTERISTICS

　　電纜額定工作電壓Uo/U為0.6/1kV

　　電纜導體長期允許工作溫度:90℃

　　電纜導體短路溫度:<250℃，持續時間:<5S

　　電纜敷設彎曲半徑:

　　單芯電纜>20倍電纜外徑

　　多芯電纜>15倍電纜外徑。

　　電纜敷設時溫度不低于0℃，低于0℃時，預先加溫，電纜敷設不受落差水平限制。

　　The permitted temperature for long-time operation:90℃Cable temp should not exceed 250℃ at a short circuit, with alasting time shorter than 5s.

　　The bend radius for laying: the one of single core cable shouldnot be shorter than twenty times of outer diam; the one of multi- core should not be shorter than fifteen times of outer diamA heating before hａnd is needed if the ambient temp.of laying islower than 0℃

　　The laying is not limited by the drop height
