FZW28 port user demarcation load switch

FZW28-12 mouth-type user boundary load switch is used at the user boundary of overhead lines, with manual and automatic operation functions. This switch adopts vacuum arc extinguishing and SF6 gas insulation. It is mainly used for breaking and closing the load current and closing short-circuit current in the power system, and at the same time, it cooperates with the front circuit breaker to realize the isolation and protection function of single-phase ground fault.<br />The product consists of three parts: switch body, control device and connecting cable.<br />The product conforms to GB3804 "3.6kV- 40.5kV high voltage AC load switch" and GB11022 "common technical requirements of high voltage switchgear and control equipment standards".
