看一下2464的style page吧，屏蔽是可有可无的。
至于外被用多少P的料，只要能通过758里面要求的物性要求就可以。

2464没有要求一定加屏蔽，可加可不加，外被用PVC，伸长达到100%以上，抗张达到1500PSI以上就可以了，55P至65P都可以。

你们所说的55P、65P的“P”是什么意思？393042706 --- 2011-07-13 15:53:57

晕，P数是胶料的软硬度，P数越高，代表胶料越软，反之则硬.

主要还是看UL的规定，2楼发的那个就是2464UL的规定，只要在这个大范围内都可以的

UL对用料的硬度没有要求的，主要看客户的使用需求！有的客户有要求特软的。我们常规用Shore A80(60P) 左右即可。
