Company Profile

The company was founded in 1985 and was officially approved by the former Henan Provincial Department of Mechanical Industry and the Henan Provincial Science and Technology Committee in May 1993 in Zhengzhou. In August 2007, it relocated to Pingdingshan City and completed its corporate restructuring in September 2017. With over 30 years of development, the company has established a national standard laboratory and testing systems, evolving into a third-party testing organization with relatively high technical expertise in China.

The company's business scope encompasses testing, inspection, and research on high, medium, and low-voltage electrical products. It also provides testing services such as type tests, performance tests, and equipment sampling for society. The testing range covers various electrical products, including switches and distribution transformers. Testing projects include insulation tests, mechanical tests, temperature rise tests, short-time withstand current and peak withstand current tests, short-circuit closing and opening tests, electromagnetic compatibility tests, and protection level verification. Currently, the high-capacity testing capabilities meet the requirements for a full set of 363kV, as well as partial tests for 420/550kV. Insulation, thermal-mechanical, and dynamic thermal stability testing capabilities cover all switchgear products up to 1100kV.
