1.電纜按(an)電壓等(deng)級分類
電力電纜般是按一定電(dian)(dian)(dian)(dian)壓(ya)(ya)等(deng)(deng)(deng)級(ji)(ji)制造的(de)，電(dian)(dian)(dian)(dian)壓(ya)(ya)等(deng)(deng)(deng)級(ji)(ji)依次為0.5kV、1、 3、6、10、20、35、60、110、 220、330kV。其中(zhong)1kV電(dian)(dian)(dian)(dian)壓(ya)(ya)等(deng)(deng)(deng)級(ji)(ji)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)使用(yong)最多。3~35kV電(dian)(dian)(dian)(dian)壓(ya)(ya)等(deng)(deng)(deng)級(ji)(ji)的(de)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)在(zai)大(da)中(zhong)型(xing)建筑內主要(yao)供電(dian)(dian)(dian)(dian)線路常(chang)有采用(yong)。60~330kV 電(dian)(dian)(dian)(dian)壓(ya)(ya)等(deng)(deng)(deng)級(ji)(ji)的(de)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)使用(yong)在(zai)不宜采用(yong)架空導線的(de)送電(dian)(dian)(dian)(dian)線路以及過(guo)江、海底敷設等(deng)(deng)(deng)場合(he)。按電(dian)(dian)(dian)(dian)壓(ya)(ya)粗分(fen)可分(fen)為低壓(ya)(ya)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(小于1kV)和(he)高壓(ya)(ya)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(大(da)于1kV)。 從施工技(ji)術要(yao)求(qiu)、電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)接(jie)頭、電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)終端頭結(jie)構特征及運行維護等(deng)(deng)(deng)方面考慮，也分(fen)為低電(dian)(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、中(zhong)電(dian)(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(1~10kV)、高電(dian)(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)。
