FKW28-12 outdoor intelligent vacuum load switch

Overview
FKW28-12 outdoor intelligent vacuum load switch is a new generation of load switch for 10kV overhead power distribution system, with manual and electric operation functions. The switch adopts vacuum arc extinguishing, zero gauge pressure SF6 gas external insulation, no possibility of gas leakage, high reliability and maintenance-free.
FKW28-12 vacuum load switch can be widely used in the construction and renovation of 10kV overhead lines in urban distribution networks and 10kV power supply lines in rural power grids. Such as supporting the distribution network automation remote terminal, it can cooperate to realize the user demarcation function.
