Company Profile

Beijing ZhongRuiHe Electrical Co., Ltd. was founded in 2009, located in Niulanshan Industrial Park, near to Beijing International Airport.

Since the establishment, we are always focused on the research and development of transformer Explosion & fire prevention technologies.

Transformer Explosion-proof and Fire Protection Equipment(TEFPE) is one of the best solution, which has been used and accepted by Chinese and many other country's customers coming from many parts of the word: South-East Asia: Indonesia PLN/ Philippines NGCP/ Thailand; Africa Ghana/Kenya; South America Ecuador/ Honduras/Mexico /Brazil; central Asia Belarus etc.

We also developed other series new products, such as Buchholz Relay fault recorder, which can be used to record oil flow speed in the pipe between oil conservator and main tank at that moment when electrical fault occurring.

For the insulation monitoring of high-voltage motors, we could offer an effective solution, ZJC series High-voltage Insulation Online Monitoring System. This new technology makes the remote measurement of high-voltage insulation resistances, leakage current, absorptance, polarization index come into reality;

We hold on the “first-class management & first quality” enterprise logos, fully adopted the following certificates:

ISO9001, ISO14001, OHSAS18001, 3C; KEMA (DEKRA); UL; CE.
