1.General description
Product features:
40.5kV series vacuum interrupter adopts a ceramic insulating shell, a middle sealing or built-in fixed shielding tube, and cooper 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:
Matched with relevant indoor&outdoor vacuum circuit breaker or vacuum distribution device, it is especially as control and protection device in the transmission and distribution electrical power grids with frequency 50Hz/60Hz, rated voltage 40.5kV, rated current 630A-2500A, rated short circuit breaking current 12.5kA-31.5kA.
VI is mainly applied to VFZN21-40.5 series indoor MV load break switch.
Meets or exceeds the requirement of IEC60265-1 and E1 level in GB/T3804-2004.
