FKW18-11kV Outdoor High Voltage Air Load Break Switch

This 11kv load break switch is a new type of load switch designed and manufactured by integrating the mature experience of domestic existing load switch production and foreign advanced technology. The high voltage load break switch is composed of isolation knife, arc extinguishing chamber and operating mechanism. It adopts the principle of compressed gas generation and arc extinguishing, which has the advantages of simple structure, low maintenance, strong arc extinguishing ability, high fracture insulation level, and high reliability, reaching the level of similar foreign products. This switch is suitable for outdoor three -phase AC power distribution system with rated voltage below 12kV and rated frequency of 50Hz to suit the load current. In the open position, it can meet the isolation requirements specified for the disconnecting switch.
