由于制造、运输等的原因,目前在阳谷电缆的施工中经常碰到电缆护层在进入管道前就已经破损的现象

技术原则中规定,阳谷电缆在敷设后、接头前、后均用100V摇表进行摇测,竣工交接时进行10kV1分钟的耐压试验,在实际施工中,经常碰到这样一种情况:施工过程中绝缘摇测状况表明一切正常,但一且竣工试验却通不过,但此时所有电缆接头均已安装完毕,往往只好将就竣工投运。如果考虑将护层耐压试验提前,即在施工过程中的适当时候(接头前)对护层进行10kⅥ分钟的耐压,一时发现护层有问题,测故障、修故障均比较便当,而竣工交接时可考虑适当降低标准,以免耐压打坏了又无法修理,毕竟有特定绝缘水平(即使达不到标准)总归比耐压击穿要好的多。【具体可参考《做好5个细节,让阳谷电缆线路冬季好眠》的相关内容】
