HZHD-523 Cable Sheath Fault Pinpoint Locator


Product overview 

With the city network development, many power supply 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 cant 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.

The output voltage of high voltage cable sheath fault detector is 10KV and below, fully meet the sheath voltage test China provisions of the national standard GB50150-2006, including suitable cross interconnected system of cable sheath and preventive test and acceptance test of cable sheath fault location. Fast and accurate detect 10kv-500kv single core and three cores HV and UHV cable sheath grounding fault and leakage current too large and other hazards, At same time, used for DC voltage withstand testing of the 5kv-10kv HDPE and PVC sheath for 1 minutes, it is the necessary equipment using for maintenance of 10kv-500kv single core and three core HV and UHV cables.
