2楼解释得很好.另外
绝缘应紧密,同心地挤包在内导体上.其外景和最小厚度应符合表中的规定.聚乙稀 绝缘料应不低于HG2--1398中电缆料的规定,但其中介质损耗角正切应不大于2.5x10-4.
编织角不大于45。.
护套应使用能使产品性能符合本标准规定的材料制造,其中Ⅲ型护套料应符合GB8815的规定. 护套一般为黑色.

介绍的很好啊！不过可以再给我解释一些东西吗？主要还是命名上的，比如SYV—50—41中的41是什么意思？还有就是SYV—50—7—41中的7和41又是什么意思？YV-50-3-41SYV-50-3-41SYV-50-3-41
zhyx2006 --- 2008-03-23 17:07:12

SYV—50—41没有这个说法而SYV—50—7—41中7是绝缘外经，50-7的标称绝缘外经为7.25
±0.25至于41就是个编号
