Vacuum Interrupter Of Load Switch/VI of VCB

Joyelectric International is a professional manufacturer, supplier and distributor of vacuum interrupter of load switch in China, welcome to order vacuum interrupter of load switch products from our factory and company.

Our vacuum interrupter has glass or ceramic envelope, middle-seal or inner fixed shield and CuCr contact material. The optimized design of cup-shape axial magnetic field electrode makes its magnetic field distribution reasonable and uniform which can increase the stability of breaking capacity. The special conditionning process improves the insulating level. Vacuum has today largely replaced other arc-quenching media, such as oil or SF6 gas, for many switching applications in the medium-voltage sector.

Features:

§ Long life, high reliability and performance

§ Fast interrupting speed and short arcing time

§ Rapid dielectric recovery

§ High cycle withstand voltages

§ Environmentally friendly

Vacuum Interrupter (VI) Production Process

Raw material puchasing→Parts maufacturing→Cleaning→Assembling→Vacuum brazing→Vacuum degree check→High voltage aging→Coating→Final inspection

QC on VI before Ex-works

Vacuum interrupter after brazing→Appearance, dimesnions inspection→X ray tester to inspect inner structure→High voltage insulation test (power frequency withstand voltage, lighting impulse voltage)→Vacuum degree check→Leak test loaded by high pressure→vacuum degree check→Comprehensive tests (comprehensive parameter, withstand voltage, vacuum degree)→EX-WORKS

The vacuum interrupters are used on load switch.

Rated voltage: 12~40.5kV

Rated current: 6300A

Rated short circuit withstand current: 20kA~25kA
