Products Description
Â
FZW32-12/40.5 outdoor high-voltage isolation vacuum load switch is a new generation of high-voltage electrical products jointly developed by our company and Liaoning Electric Power Research Institute High Voltage Institute. After strict type test and long-term trial operation, all the technical performance indexes have reached GB3408 and 1EC standards, and it is suitable for the power supply network with rated voltage of 12KV, rated current of 630A and three-phase alternating current of 50H2.

Details of Product
Â
FN12-12D combination electrical appliance is a three-phase high-voltage switch with a rated voltage of 12KV and a rated frequency of 50Hz. It is used for breaking and closing load current, closing loop current, no-load transformer and cable charging current. To reduce the short-circuit current, the fuse combination appliance can break the short-circuit current, and the load switch equipped with a grounding switch can withstand the short-circuit current.
