++++General:
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.
++++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.
e)No frequent violent shake.
