a. Form high strength axial magnetic field, and strong capability for breaking current as well as high reliability.
b. Integrated contact terminal, no slot on the surface of contact to the lead the arc, perfect surface geometrical shape, high electrical strength, outstanding mechanical strength and no deformation when we open or close the switch.
c. Little resistance in circuit Ir=1250A,R=9±1uΩ;Ir=3150A R=7±1uΩ.
d. Meet the user' s requirements of 100% full capacity breaking at the first time and rated electric parameters.
e. symmetrical electrical field, low chopping current, high reliability of breaking capacitor and inductance.
B.Stainless steel directly braze welding
a. Special stainless steel braze welding in which it is not necessary for stainless steel to be plated with Nickel therefore the quality of welding is high and steady as well reliable, meanwhile, the rate of leaking air is low.
b. Special stainless steel features in strong capability to resist the salt mist, which can be applied in wide areas.
c. Stainless steel is characterized by high tensile resistance, tactility and impact resistance.
C.first-class Metallization technical
a. Special ceramic metallization format and advanced ceramic metallization technical guarantees the air tightness of products and high intensity of tension,that is, the minimum intensity of tension reaches 130Mpa.
b. Import the advanced metallization equipment to ensure the conformity and rate of finished products of ceramic metallization technical.
c. Improved inspection methods of ceramic and metallization strength ensures the metallization quality of ceramic shell being stable and reliable in the of integrated tube?
D. Complete once-for-all sealing technology
a. The technology eliminates necessity for component welding, reduces the work of man power, therefore the simple technical ensure the stability of products quality accordingly.
b. The imported advanced vacuum sealing furnace is controlled by computer with no manned operation, which guarantees stable and reliable manufacturing.

c. Complete once-for-all sealing technical possesses short circuit and high efficiency for assembly suitable to large-Cscale production.


Advanced Technology

Complete once-for-all sealing furnace is designed and manufactured by international well-known professional device company, being the core device to manufacture the VI in our company, its advantages are followed:
a. Adopt the vacuum system with fully oil free, mean while, during the process of welding the VI, it is not polluted by oil steam.
b. Adopt two large-size turbo molecular pumps to provide the quick pumping speed and high ultimate vacuum.
c. Widely effective volume areas and evenly distribution of the temperature are appropriate for complete once-for-all sealing of VI.
d. It is controlled by computer and operated through no manned intelligent, furthermore, its technical curve is accuracy, which is very helpful for products' evenness.
Automatically plate hydrogen oven is designed and manufactured by international well-known professional device company, being the key device of ceramic metallization technical and exerting direct and great effects on ceramic metallization fabrication quality of insulated ceramic shell in the VI, its advantages are followed:
a. The device is controlled by computer, thereby its accuracy for control temperature is high and running is steady and reliable.
b. Automatic, consistent, reliable and cyclic feeding and outgoing products is useful for high rate of finished products in terms of ceramic metallization, good conformity, reasonable distribution grad of temperature, small stressed main body of ceramic shell and metallization coating and glaze is stressed light and being reliable.
c. The coat of metallization ceramic shell is artistic and smooth as well as tightness; outstanding air tightness of metallization coating and high strength, at the same time, it' s minimum intensity of tension reaching 130Mpa.
