UL不允許的

能提供一點左證嗎?謝謝!

希望繼續(xù)討論,各位都可以發(fā)表下自己的看法!

不好控制

工藝上怎么個不好控制? 發(fā)炮度? 押出難? 還是怎么著?

如果使用免對排線機(jī)頭這樣作業(yè)還是很順利的

如果有UL marking最好是不讓他們發(fā)現(xiàn)

發(fā)泡的應(yīng)該很難控制吧。Belden有專利但是 是 Lan Cable 比較好控制。

押出后受壓力不同可能更容易導(dǎo)致 Skew Fail；

余 兄 如果有UL marking最好是不讓他們發(fā)現(xiàn)  和UL 有什么關(guān)系？

10樓也有提到,如果用2725的話,2725的結(jié)構(gòu)芯線不允許用并線的,這個你可以去問你們廠那個UL查廠的就可以了,他可以給你比較詳細(xì)的解釋,聽說曾經(jīng)東莞有一家給查到了這個問題,而且后果比較嚴(yán)重.

我們以前用的就是並來的很難做

對于FoamPE絕緣芯線,常用的style為1598,這些只能生產(chǎn)單芯結(jié)構(gòu),是不允許這樣生產(chǎn)的

當(dāng)然,如果你們公司有相對應(yīng)的結(jié)構(gòu)認(rèn)證,還是沒問題的

請問樓上：FoamPE絕緣芯線用UL1598和UL1589有何區(qū)別?

我主要是想問：May be crosslinked．是什麼意思？

如果使用並行粘連結(jié)構(gòu)就使用什麼號碼？

余澤平前輩：

　　　　　你說用免對排線機(jī)頭好做．是做的發(fā)泡PE嗎？請?zhí)峁┮幌聶C(jī)頭供應(yīng)商，模具供應(yīng)商．

謝!
