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!
