Introducing our incredible 40.5kV series vacuum interrupter! This cutting-edge device is designed with a ceramic insulating shell, a middle sealing or built-in fixed shielding tube, and features cooper and chromium alloy contact material. But that's not all - we've taken it a step further by optimizing the structure design of the cup-shaped longitudinal magnetic electrode. This ensures that the electromagnetic field distribution is not only uniform, but also incredibly reasonable, resulting in improved stability of the breaking capacity. And let's not forget about the insulation level - we've gone above and beyond to enhance it with our special sophisticated process.
Now, let's talk about applications. Our 40.5kV series vacuum interrupter is the perfect match for relevant indoor and outdoor vacuum circuit breakers or vacuum distribution devices. It truly shines as a control and protection device in transmission and distribution electrical power grids with a frequency of 50Hz/60Hz. With a rated voltage of 40.5kV, rated current ranging from 630A to 2500A, and a rated short circuit breaking current of 12.5kA to 31.5kA, this interrupter is ready to take on any challenge. 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.
So, if you're in need of a high voltage ceramic vacuum interrupter for your load break switch, look no further! Our 36kV 40.5kV High Voltage Ceramic Vacuum Interrupter is the answer. With keywords like Vacuum Interrupter, Hv Vacuum Interrupter, and 36kV Vacuum Interrupter, you can be sure to find exactly what you're looking for.
