With the full deployment of urban network transformation, many power supply bureaus, construction parties, and design units are encountering 110kV XLPE cables for the first time. Due to time constraints and insufficient experience, many cables fail to pass the withstand voltage test (10kV/1min).
Most outer sheaths are made of HDPE material, which passes factory DC 25kV/5min withstand voltage tests with leakage currents as low as tens of μA. Post-installation defects are typically caused by external damage during laying, while operational defects include termite damage, water ingress in grounding boxes, moisture penetration, and insulation resistance reduction.
Our high-voltage cable outer sheath fault detector with 10kV output meets Chinese national standard GB50150-2006 requirements, performing both withstand voltage tests and fault location for cable outer sheaths in cross-interconnect systems. It quickly identifies hidden dangers in 10kV-500kV single-core and three-core high-voltage cables.
