Wuhan Feite Electric Co., Ltd. is a hi-tech enterprise specialized in producing vacuum interrupter,vacuum circuit breaker,vacuum contactor and load break switch. Our company has a group of experts and technicians who have been specialized in producing vacuum interrupters for more than thirty years, and enjoys the tax preferential policy as a hi-tech enterprise. Products and technology of our company Our company has developed 1.14kv-40.5kv vacuum switch tubes of more than 100 types, which can be widely used for various vacuum circuit breakers, contactors and load break switches. As an ISO9001:2000 certified company, our production process strictly conforms to quality management system. Since the company has successfully developed ZN-28A-12, ZN23 -40.5 series of a vacuum circuit breaker, we engaged in development and produce 40. 5kv or lower voltage vacuum circuit breakers, vacuum contactor, vacuum load break switch all along. Our 12-40.5kv vacuum circuit breakers are published in Recommend device and manufacture for national urban and rural power grid construction and reform issued by State Economic and Trade Commission. The optimum design of our vacuum switch tubes has been developed by our company together with prestigious institute, making diameters and measurements greatly matches to electric field. The leakage rate has been controlled in less than one-thousandth by Once Seal-Exhaust Technique, making technical data (such as contact bouncing duration) can be easily adjusted during mounting process, and mechanical life of our products can be largely enhanced. We have already acquired the national patents including 2009200832892, 2009200834277, 200920083534X, 2009200835320, 2009200835335, and 2009200832905. Component and material supply Metalized ceramic: The density is much higher than injection molding, so the welding ability is great. Contact terminal: High quality imported CuCr25, CuW Bellows: 316L Stainless steel, easy-welding and environmental friendly, which is much better than common 304 and 321. Production control and technical innovation a. The production procession has adopted advanced control technology, to eliminate discrete and ensure consistency of product quality and improve product qualified rate. b. Each batch of bellows can only be put into production after passing 10 million times of life test after mechanical forming. Also, metalized ceramic are 100% non-leakage required during the air tightness test and the seal strength is over 5000N. c. Oxygen-free copper ring transition in sealing structure has solved problems such as low seal intensity and tube easy-breaking, so that the product life is greatly enhanced. d. Free painting technology: Current domestic product with spray paint on the stainless steel surface will cause a certain degree of pollution. To solve this problem, we use special microelements solder materials to prevent it from dispersed around product surface, which is natural, beauty and environmental friendly. e. Once Seal-Exhaust Technique: All the components will be assembled in the Once Seal-Exhaust furnace in one time. Thus, production process has been optimized .Also, duplication and pollution can be avoided effectively. This technique has filled our domestic blank. Personnel structure Our company has 128 staff members at present, including 28 senior and medium class technicians, 2 experts of provincial and ministry level. Business concept The company persistently sticks to synchronization of management innovation and technical innovation. We are not only constantly expanding sales network, but also introducing modern management pattern, ceaselessly promoting management, optimizing and perfecting management structure. We will keep the quality commitments to customers, and ceaselessly offer perfect service to all the customers. Feite believes that we will have a brighter future!
