Product Description

DESCRIPTION

LRFW-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.
