Baoding Tianwei Electric Wire Co., Ltd. (BTEW) is one of the subsidiaries of Tianwei Group with independent legal personality; BTEW is a manufacturer that mainly produces transformer electromagnetic wires which was set up in 1968. Now the total register capital is RMB450million, the register capital is 100 million RMB. Baoding Tianwei Electric Wire Co., Ltd. (BTEW) is now located at Tianwei Industrial Park of Baoding High-tech Industrial Development Zone and built up garden-style factory, which covers 40772m2. The entire airtight workshop is dust-proof and purified, the fall-dusts amount per day is ≤8mg/m2 , the workshop temperature is controlled by the central air conditioner. The BTEW possesses state-of-the-art extruding lines, flat enameling machines, and the CTC production lines, which has an annual production capacity of 10000t CTC, 10000t combined wires and paper wrapped wires, 10000t non-oxygen copper rod. BTEW is devoted to diversification development, set up 4 branches of Tianwei Hexing Electric Fitting Co., Ltd., Tianwei Hexin Metal Material Co., Ltd., Tianwei Huake Electric Wire Co., Ltd., and Hefei Tianwei Electric Wire Co., Ltd., it makes the BTEW to modern enterprise with integration and industrialization of production, marketing, service, R&D. BTEW has a large number of specialized personnel on making, testing, inspection and R&D for electromagnetic wires. Since 1998, strong technical supporting from Tianwei Group, we had successfully developed series of transformer electromagnetic wires on the basis of paper wrapped single conductor and paper wrapped combined conductors. Our company had successively developed more than ten kinds of new products, such as polyacetal enameled flat copper conductor, polyester enameled flat copper conductor, polyamide-imide enameled flat copper conductor , heat-bonding enameled flat copper conductor, enameled Semi-hard heat-bonding flat copper, heat-bonding CTC, heat-bonding Semi-hard CTC, netting heat-bonding Semi-hard CTC, Semi-hard paper-wrapped single conductor, Semi-hard paper-wrapped combined conductors, reactor-used paper wrapped conductors, electromagnetic wires for shell-transformer, etc.，especially in the recent years, we developed combined CTC, stepping CTC and screening CTC for DC transformer, its technical level has been reached leading position in China. The products are mainly used for 220kV, 500 kV, ±800kV、1000kV and above transformers, super-voltage, high-capacity transformers and 500 kV reactors. Among them, we have possessed the independent intellectual property right of the netting heat-bonding CTC and its independent manufacturing technology had been sanctioned by State Intellectual Property Office (SIPO) for the patent. Now the netting heat-bonding CTC has become the leading products of BTEW and the main motive force of the economic growth. BTEW gained the title of “Quality and Profit Advanced Enterprise of Hebei Province” in 2006, the “Excellent Invention and Creativity Enterprise of Hebei Province” in 2009. BTEW has been persisting in the enterprise principles to “win market with quantity, to develop with innovation, to get profit with management” , and will unify the programs, use resources rationally, keep up its development continuously, healthily and rapidly, and do its best to create the “Tianwei Wire” international brand, also an electromagnetic wires production base which will take lead in China and be of the fist-class in the world.
