40.5kV Vacuum Interrupter/36kV Vacuum Interrupter/High Voltage Vacuum Interrupter/HV VI
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.
●Long life, high reliability and performance
●Fast interrupting speed and short arcing time
●Rapid dielectric recovery
●High cycle withstand voltages
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
Rated voltage: 40.5kV
Rated current: 1250A~3150A
Rated short circuit withstand current: 12.5kA~31.5kA
The vacuum interrupters can be used on ABB, Siemens and Schneider VCB, and for load break switch and recloser, etc.
