客戶(hù)在ABC電纜的標(biāo)識(shí)規(guī)范中有如下描述:
Aerial cables which consist more than one insulated conductor shall have the outer surface of individual insulated conductor cables durably marked throughout the cables length with means of individual phase identification.
請(qǐng)問(wèn)這是什么意思?

PLWH:就是為了區(qū)分A、B、C三相序的方法。GB 12527、GB 14049中的3+K型帶承載絞線(xiàn)的架空絕緣電纜(類(lèi)似ABC電纜),即采用絕緣表面凸脊標(biāo)志:A相為1根凸脊,B相為2根凸脊,C相為3根凸脊。也可以采用噴碼數(shù)字標(biāo)識(shí)等方式。
請(qǐng)問(wèn)一下,凸脊有沒(méi)有要求,例如凸脊寬度、高度、凸脊之間的寬度是多少?能否解答一下下,謝謝
