Chongqing Weineng Oil Purification Solutions Co., Ltd., a professional manufacturer of transformer oil treatment and testing equipment, officially releases its newly upgraded IIJ-II series transformer oil breakdown voltage tester, completing a full set of oil detection and purification equipment for power stations, substations and power engineering contractors worldwide. Paired with the company’s flagship ZYD double stage vacuum transformer oil purifier, the integrated system realizes full-cycle oil quality management, effectively removing moisture, gas and particulate impurities to recover transformer oil breakdown voltage above 75kV.

Transformer insulating oil serves as the core insulation and cooling medium for high-voltage transformers. Long-term operation introduces water, dissolved gas and solid contaminants, which sharply reduce dielectric strength and trigger hidden risks of transformer breakdown. Power operators need reliable testing tools to monitor oil conditions and professional purification equipment to regenerate degraded oil on-site.

The newly launched IIJ-II transformer oil breakdown voltage tester delivers stable, precise dielectric strength measurement for insulating oil. Adopting microcomputer automatic control, it supports one-click full-automatic testing, built-in data storage and printing functions, compatible with IEC, ASTM and global mainstream power industry standards. Featuring anti-interference circuit design and comprehensive overvoltage/overcurrent safety protection, the compact IIJ-II transformer oil breakdown voltage tester adapts to both laboratory routine inspection and outdoor field sampling tests, helping engineers accurately judge oil degradation levels quickly.

For on-site oil regeneration and restoration, Weineng’s mature ZYD series double stage vacuum transformer oil purifier acts as the perfect matching solution. Equipped with double high-vacuum separation systems and multi-stage precision filtration modules, the machine executes three core purification functions simultaneously: deep dehydration, degassing and particle impurity removal. After treatment, deteriorated transformer oil regains qualified insulation performance with breakdown voltage restored to over 75kV, eliminating the need for frequent oil replacement and cutting power operation costs significantly.

“Many power clients used to face separated oil testing and oil purification workflows, leading to low maintenance efficiency,” said the Sales Director of Chongqing Weineng Oil Purification Solutions Co., Ltd. “The launch of IIJ-II transformer oil breakdown voltage tester forms a closed-loop solution with our ZYD vacuum oil purifier. Clients can test oil breakdown voltage before and after purification to clearly verify purification results. This all-in-one solution reduces transformer failure risks, extends oil service life and lowers long-term operational expenditure for power assets.”

The ZYD double stage vacuum oil purifier covers multiple specifications including mobile wheeled and trailer-mounted models, supporting batch oil treatment for large power transformers in power plants, wind farms and industrial substations. All equipment supports PLC automatic operation, CE and ISO certification, and customized design for global customers. Combined with the IIJ-II transformer oil breakdown voltage tester, Weineng provides one-stop oil quality control solutions for power maintenance teams across Asia, Africa, Europe and Latin America.

Weineng welcomes global power equipment distributors, power engineering companies and utility operators to inquire about technical parameters, on-site test cases and OEM cooperation. The company offers professional after-sales technical guidance and overseas installation training to advance long-term win-win partnerships with worldwide clients.
