UL1007的22AWG線材的內芯是0.15*17股裸銅，請問光從內芯看合格嗎?

還有請問一下這個標準哪有下載？

萬分感謝�。�！

你可以要求你的供應商提供線材的規(guī)格書，也可以參照別家公司擔供的規(guī)格書來檢驗

這種標準的規(guī)格我們公司都很少檢的，供應商連這種材料都要懷疑的話那當初為什么要選用

從截面來算已經不合格，具體可參照UL 758 表52，導體的外形尺寸。

但是要判斷此導體是否合格，最終還是要測量導體電阻是否合格。

一般都用17/0.16TS

導體0.15*17股，不對吧，導體截面積才0.3，UL規(guī)定最小要0.318.

如圖：

肯定不合格啦！應該是17/0.16的
