                产品案例

                20kV交联电力电缆“死接地”故障案例

                案例背景:

                线路名称:XXX226纳米#6线出线

                测试地点:XXXX开闭所

                测试时间:20210113

                电缆类型:YJV22-12/20kV-3*400

                电缆长度:2300m

                此条线路电缆排管敷设,线路在运行过程中发生※接地故障,经过现场巡视勘查,发现线路上有施工工地进行了打孔施工,怀疑电↘缆被打坏,但由于电缆埋深2m以上,无法直接确定故障点。
