Pole-mounted load-break switch(Pole-LBS) applies up to 36KV 400/630A, 50Hz pole-LBS associated with a state-of- the-art controller. This SF6 gas-insulated switch can corporate with the distribution automation system, and also isolate section of distribution line from the control center.

A simple pole-mounting arrangement contribute to quickand low cost installation, and the swtch 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 b prvided mounting wire or wireles modem in a cabinet.
