SUNWAY HANGUANG Electric Manufacturing Inc.hasbeen specializing in wide range of high quality vacuum interrupters for medium and high voltage switchgear application since 1989¨s.Outstanding vacuum interrupter manufacturing techniques used by SWHGE result in the highest quality and largest breaking current range of vacuum interrupters available today.
SWHGE is specialized in development and production of ceramic vacuum interrupters. It is able to produce 120,000 every year.
1)Main features
，High quality vacuum interrupter design.
，Simplified arc quenching method
，Robust compact construction.
，Slim body design.
，High reliability.
2)Major applications
，Vacuum interrupters for circuit breakers
，Vacuum interrupters for switches
，Vacuum interrupters for contactors
，Vacuum interrupters for capacitor bank switching
，Vacuum interrupters for reclosers
，Vacuum interrupters for rail circuit breakers
Our vacuum interrupters are available in several designs and for multitude of switching applications; we offer compliance to ANSI, IEC, GB and JIS standards.
3)Technological characteristics of the product
，the cup-type electrode simulations of 3D axial magnetic field technology
Within the vacuum interrupter, the cup-type electrode simulations of 3D axial magnetic field, developed independently by us was utilized . With advanced design, the contact system has high structural strength and strong switching capacity. The vacuum interrupter is characterized by its resistance to deformation, high reliability, and low circuit resistance and especially by its features in switching capacitance.
，Sealling technology
Within the sealling technology of the VI, the stainless steel connected with ceramic directly. The utilization over a large extent had confirmed their satisfactory sealing capacity, high strength and high resistance to corrosion.
A complete once-for-all sealling technology was utilized in the sealling of VI. The technology eliminated necessity for component manufacturing, outlet sealling of the entire tube and gas-discharging process and significantly increased production efficiency accordingly. With less working procedures and less influence of human factors, the product is characterized by high conformity and high reliability.
，Advanced metallized ceramics for applications
In our advanced materials division, we have initiated with innovate technology to manufacture our fine ceramics, especially high alumina and metallized products for our company. Our processing technologies are:
Metallizing
High temp glazing
Electrolytic& electroless plating
50 years of electronic tubes design and manufacturing experience.
20 years of vacuum interrupters design and manufacturing experience.
4) Major equipment
World famous professional manufacturers manufactured all major process, and first-class domestic manufacturers manufactured all auxiliary equipment.
Major process equipment:
n Vacuum oven with one-off sealling (PVA of German and BREW of USA): Controlled by computer and PLC for sealed connection of the vacuum interrupters.
n Automatic hydrogen oven (FHD of UK): with computerized and PLC control, the equipmentcan be utilized for metallization of ceramic. It is the horizontal metallization hydrogen oven with the most advanced technology indexes and largest workable ceramic sizes in China at present.
