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 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.

RSW type vacuum load break switch can be combinated with CT/PT and Smart controller then achieve a smart sectionalizer, which is muti-function load break switch with senior relay protection and communication.


Service environment:

a)Air temperature: Maximum temperature:+85℃; Minimum temperature:-45℃.

b)Humidity:Monthlu average humidity 95%; Daily average humidity 90%.

c)Altitude above sea level:Maximum installation altitude:2500m or higher.

d)Ambient air not apparently polluted by corrosive and flammable gas, vapor, etc.
