Baoding Tianwei Wire Manufacturing Co., Ltd.(BTWM) is one of subsidiaries of Baoding Tianwei Baobian Electric Co., Ltd, which is the unique state-owned enterprise producing the high-end electro-magnetic wires applied in transformers. The registered capital is RMB182million yuan.
Baoding Tianwei Wire Manufacturing Co., Ltd. (BTEW) is now located at Tianwei Industrial Park of Baoding High-tech Industrial Development Zone with garden type factory. It is the first company in China with the entire airtight, dust-proof and purified, and central air conditioner in the electro-magnetic wire field. The BTW M possesses state-of-the-art extruding lines, flat enameling machines, and the CTC production lines in the world, which has an annual production capacity of 10000t CTC, 10000t combined wires and paper wrapped wires.
BTWM is focus on all kinds of top-end electro-magnetic wire manufacturing and R&D, and has a large number of talents committing to test and inspection, manufacturing and development of electro-magnetic wire. Based on the paper-wrapped conductor and paper-wrapped combined conductor, we developed a series of electro-magnetic wire using in transformers. We can supply many kind of wires such as PVA enameled flat, polyester imide enameled flat, polyamide enameled flat, film-wrapped wire and abnormity wire, heating-adhesive enameled flat, heating-adhesive semi-harden enameled flat, heating-adhesive CTC, heating-adhesive semi-harden CTC, heating-adhesive netting tap CTC, semi-harden paper-wrapped conductor, semi-harden paper-wrapped combined conductor, reactor paper-wrapped winding conductor, shell-type transformers specially conductor, etc.. The specially using in the DC transformers CTC wire developed by BTWM, which is the combined CTC, the stepping CTC, the screened CTC, its technology level is in leading in the electro-magnetic wire field in China. Among them, the heating-adhesive netting tap CTC has the owned intellectual property rights and independently manufacturing technology, it has been approved the patent product by the National Patent Bureau. It has become the dominating product and profitable product. The reactor paper-wrapped winding conductor, the special DC transformer CTC products has been approved as the key and new type products by China. 
BTWM has been persisting in the enterprise principles to “win market with quantity, to develop with innovation, to get profit with management”, and makes great efforts to create an electromagnetic wires production base leading in China and the world, and the famous brand.
