各位大虾,想请教一下,UL1571线材是怎样设计的,芯线的大小,铜线的绞距,和外被的最小绝缘厚度和最大绝缘厚度是怎么样来决定的,绝缘的材质是什么?有没有这方面相关的资料可以给小弟参考一下,要中文版的,如哪位大哥,大姐有这方面的资料可以在这上面指导,也可以发EM给我,EM:1133052@163.COM,不胜感谢!
多看看UL758就OK了
是但到论坛去下U758了解即可;
被人给你的不是很权威,是他人的经验所以建议自己去找这样记忆比较深刻.
1571 在 UL758 STYLE PAGE 里面找.具体规格要求会写的很详细;

一般绝缘用半硬PVC,如果绝缘很薄的话，半硬PVC要特殊生产。因为容易绝缘回缩，破裂。
我有。

不要光照著理論上的數據去做，這類線一般被用在沖電器的聯接線，是要有屈曲強度要求的哦，電線好做，如果要滿足屈曲測試的要求，恐怕沒那麼簡單吧~~！嘿
