Vacuum Interrupter 12kV (VAC307)

12kV series vacuum interrupter adopts a ceramic insulating shell, a middle sealing or built-in fixed shielding tube, and copper and chromium alloy contact material. Optimizations of the structure design of the cup-shaped longitudinal magnetic electrode makes the electromagnetic field distribution uniform, reasonable, and improve the stability of the breaking capacity. Special sophisticated process improves the insulation level of the product.

Vacuum interrupter for vacuum circuit breaker

TD-12/2000-40(VAC307)


1.General description


Product features:

    12kV series vacuum interrupter adopts a ceramic insulating shell, a middle sealing or built-in fixed shielding tube, and copper and chromium alloy contact material. Optimizations of the structure design of the cup-shaped longitudinal magnetic electrode makes the electromagnetic field distribution uniform, reasonable, and improve the stability of the breaking capacity. Special sophisticated process improves the insulation level of the product.


Application:

    In order to meet the requirement of customers, VACEM introduced two series of 12kV vacuum interrupter (for air insulation, embedded insulation or need external insulation protection ) to match with relevant indoor&outdoor vacuum circuit breaker or vacuum distribution device. It is especially useful as control and protection device in the transmission and distribution electrical power grids with frequency 50Hz/60Hz, rated voltage 12kV, rated current 630A-4000A, rated short circuit breaking current 5kA-40kA.

VI is mainly applied to VZN63-12kV series indoor MV vacuum circuit breaker.
Meets or exceeds the requirement of IEC62271-100 and E2 level in GB1984-2003.
