Manufacturer and exporter

Anhui Hengyuan Power Equipment Co., Ltd. develops, manufactures and exports power transformers and distribution equipment for grid, industrial and renewable applications.

Who we are

Our range covers three-phase and single-phase oil-immersed distribution transformers, cast-resin dry-type transformers, packaged substations and switchgear from 6.6 kV to 35 kV, in capacities from 30 to 2500 kVA.

Sales, export and customer service are handled by Anhui Hengyuan Power Equipment Co., Ltd. Production takes place at our own manufacturing base, Anhui Yifu Electrical Technology Co., Ltd. in Anqing, Anhui. The two are part of the same operation, not a trader passing orders to an unknown supplier.

Engineering, production and testing sit at that base on the Yangtze River Delta, which gives us direct control of the quality documents a buyer actually needs — test reports, drawings and nameplate data. When you ask for a certificate, it comes from the people who built the unit.

Our customers are power utilities, EPC contractors, renewable energy developers and industrial enterprises. Products are in service in distribution network upgrades and industrial power projects in China, and on export projects in Africa and Central Asia.
