SF6 Load Breaker

KEY WORDS:High pressure vacuum switch



LW34-12/24 SF6 Load Break Switch is used in outdoor 12KV or 24kV three phase AC 50/60Hz power system to open and close load current and short circuit current. It accords with the standards of IEC60265 & GB/T3804 3.6~40.5KV High voltage AC load break switch, GB/T11022 High voltage switch apparatus and control apparatus.

1、Stainless steel panel have good antisepsis and seal performance.
  2、Light in weight and convenience for transit.
  3、Free maintenance.
  4、With anti-explode device.
  5、The switch can be locked automatically when the press is 0.03 to 0.07MPa.
