Product Details

Product Name: Outdoor 12kv Vacuum Disconnecting Switch ZFN22-12

Type: Load Break Switch

It is developerd by ourselves based on FN5 type used in the network of voltage 12kv three-phase 50Hz for breaking load and switch on-and-off short-circuit current.It is equipped with novel especially-used motor mechanism to relize on-and-off and energy-storing by handle and by motor,keeping FN5switch features of impact structure and simple installation and operation It is the first-choice product for ring network and also greatly heps to replace directly vacuum load switch in the ring network cabin with FN5 switch in equipment for the transformation.
