Column installed insulation load switch, type RPS-12/27/38-20,is suitable for the rated voltage 12/27/38kV,rated current 400A,630A,50/60Hz power grid open circuit,load current in closed Power system,overload curren. This load switch can separate those broken distribution line automatically.
With the latest technology, it has the newest electronic controller.The switch can be used by manual operation, electric operation and operation from a long distance. 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 through which it can realize the remote monitoring and control. Simple installation on column is convenient, fast, and also can reduce the construction cost.
