Baoding Tianwei Baobian Electric Co., Ltd.(BTW), originated from Baoding Transformer Works founded in 1958, is one of the largest manufacturers for power transformers and modernized high technology power equipment. Products cover transformers, CT and reactors applied on power generation, transmission and distribution systems, ranging from 10kV to 1200kV, with maximum product capacity 1500MVA. Its

BTW（Qinhuangdao）Base was established in 2005 with total area more than 160 thousand ㎡. Main products are Power transformers up to 1,500MVA/ 1,000kV, Reactors up to 240 MVAR/ 1000kV, HVDC transformers up to ± 1100kV.

To adapt to the development requirements of a thrifty society，BTW has formed the mass production energy saving distribution transformer ability. The core of our series distribution transformer is made of cold-rolled oriented silicon steel with high magnetic permeability and low loss. By optimizing the design, no-load loss, load loss and noise are greatly reduced.
