FKW28-12 outdoor intelligent vacuum load switch
General introduction
FKW28-12 outdoor intelligent vacuum load switch is a new generation of 10kV overhead distribution system load switch, with manual and electric operation function. Switch adopts the vacuum interrupter, zero gauge pressure SF6 gas insulation, no possibility of gas leakage, high reliability, maintenance free.
FKW28-12 vacuum load switch can be widely used in urban distribution network 10kV overhead lines of new construction and transformation, as well as rural power grid 10kV power supply line. Such as supporting distribution automation remote terminal, can cooperate with the realization of user demarcation function.
