Product Description
GPS-7.2/12/24-20 type outdoor pole install SF6 load break switch is suitable for rated voltage 12/24/40.5kV, rated current 400A,630A 50/60Hz power gird for circuit open, load current,overload current in closed power system.This kind of load switch can seperate those broken distribution line automatically. With the latest technology, it has the newest electronic controller. The load break switch can be used by a manual operation,electric operation and remote operation. Electronic controller is installed in a stainless steel cabinet which is suitable for using under all kinds of climatic conditions. In addition, there are some wired and wireless modem installed in the cabinet to realize remote monitoring and control. Simple installation on pole can reduce the construction cost as well as convinient and fast.
