With the city network development, many power bureau, construction, and even the design institute are first met 110kV XLPE cable, due to time and lack of experience, resulting in many cable outer sheath can’t passed withstand voltage test (10kV/1min). At present, the external protective layer mostly uses HDPE sheath material, passed the DC 25kV/5min withstand voltage test before out of factory, the leakage current is less than dozens of µA. Therefore, after the laying of defects mostly by laying, including external damage during filling and covering process. The defects include termite bites; ground box with water; deterioration of the original defects; grounding wire or part moisture penetration insulation resistance decreased and other reasons, sometimes because the cable buried too deep, or the complexity of the situation around buried cable, so that the positioning is very difficult, some defects can’t be solved after many years, with the hidden danger to run.
