FKW18 This series of switches is a new type of switch designed and manufactured by integrating the mature experience of the current domestic load switch production and foreign advanced technology. The isolating load switch is composed of isolating knife, arc extinguishing chamber and operating mechanism. Using the principle of pressurized gas production and arc extinguishing, it has the advantages of simple structure, less maintenance, strong arc extinguishing ability, high fracture insulation level and high reliability, reaching the level of similar products abroad.
