HV HIPOT VLF-93AD Completes 35kV Long Cable Commissioning for 120MW Southeast Asia Hydropower Station

HV HIPOT today announced the successful completion of 35kV XLPE cable commissioning tests for a 120MW large-scale hydropower station in Southeast Asia, using its flagship VLF-93AD ultra-low frequency AC high voltage generator. The equipment operated stably for 72 consecutive hours under high-temperature and high-humidity field conditions, accurately detected joint process defects, and supported the station’s on-schedule grid connection.

Located in a mountainous tropical region, the project features a 4.2km single-section 35kV main cable. Narrow site access made large power-frequency test equipment impossible to transport, while ambient temperatures consistently exceeded 40°C, placing strict demands on equipment reliability. The client also required full-line testing to be completed within 3 days, with zero secondary damage to the XLPE cable insulation.
