LW3F type pole-install load switch was used in 12kV,24kV,33kV rated voltage, rated current 400/630A; 50/60HZ with the load current; over load current of power line open circuit and opening and closing electric systems.
The switch can equiped with a conttoller with most advanced technical parameter.
LW3F-A type LW3F is manaully LBS for choice.
LW3F-M type LW3F is a intelligent type LBS for choice. It can automatically disconnect when the distribution line was break down. It could operated by handle; Implementt electro motion and distant. The electric controller was installed in stainless steel cabinet. So it could use in any conditions.
a) Air temperature:
Maximum temperature: +40℃; Minimum temperature:-20℃
Monthly average humidity 95%; Daily average humidity 90% .
c) Altitude above sea level:
Maximum installation altitude: 2500m
d) Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.
e) No frequent violent shake
a) SF6 gas insulated : SF6 is a electric insulating gas of non-poison and nonflammable, and have a good arc suppression feature.
b) Bushing diversity: Except for standard porcelain bushing, there are also provide various rubber bushing.
c) Visible open circuit and opening and closing situation: It is easy to see the color sign of the main contact place indicator ( green open circuit; red closing). The indicator and main conductor always keep on direct connecting, make sure show the conductor state.
d) Fast operation: Used by spring stored energy operation system., make sure fast switch on and switch off operate ( no more than 1 second)
e) Could provide controller: Stocked by electric controller, could operated in ground or operate by the main controller through RTU screen
f) Solidity switch: Switch was made by solidity and anticorrosion material, make sure have a long useful life (30 years) have the pole equipment feature.
g) Standard: it will filled full SF6 before delivery, and deal with seal. Test by IEC60265; GB3804.
