RSW type pole mounted vacuum sectionalizer
RSW type Pole-mounted load-break switch(Pole-LBS) applies up to 24KV,400/630A, 50Hz pole-LBS associated with a state-of- the-art controller.
This SF6 gas-insulated switch can be corporated with the distribution automation system, and also isolate section of distribution line from the control center.
It is a simple pole-mounting arrangement contribute to quick and low cost installation, and the switch can be operated manually with a electronic controller. Electronic controller is contained in a stainless steel cabinet for an all weather environmental conditions. Remote monitoring and control can also be provided mounting wire or wireless modem in a cabinet.
RSW type vacuum load break switch can be combined with CT/PT and smart controller for achieving a smart sectionalizer, which is muti-function load break switch with senior relay protection and communication.
