DESCRIPTIONLRFW-12/24/36 pole-mounted load breaking switch is used
to rated voltage 24KV, rated current 400/630A, 50/60 Hz power
grid open circuit, load current in closed power system, overload
current. This load switch can separate those broken distribution
line automatically.The LRFW series outdoor SF6 load switch is a
three-phase AC 50Hz /60Hz outdoor medium-voltage switchgear, which
can break off and close the load current and overload current in
the power system; The load switch is equipped with intelligent
controller to realize the automation of distribution
system.Application voltage levels include 12kV, 24kV and
36kV.Application standard: IEC62271-200. 1. Lift handle
