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

2464沒有要求一定加屏蔽，可加可不加，外被用PVC，伸長達到100%以上，抗張達到1500PSI以上就可以了，55P至65P都可以。

你們所說的55P、65P的“P”是什么意思？393042706 --- 2011-07-13 15:53:57

暈，P數(shù)是膠料的軟硬度，P數(shù)越高，代表膠料越軟，反之則硬.

主要還是看UL的規(guī)定，2樓發(fā)的那個就是2464UL的規(guī)定，只要在這個大范圍內(nèi)都可以的

UL對用料的硬度沒有要求的，主要看客戶的使用需求！有的客戶有要求特軟的。我們常規(guī)用Shore A80(60P) 左右即可。
