Product Description
++++General
PGS 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.
PGS-A type PGS is manaully LBS for choice.
PGS-M type PGS 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.
++++Service environment
- Air temperature:
- Humidity:
- Altitude above sea level:
- Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.
- No frequent violent shake
++++Feature
- SF6 gas insulated : SF6 is a electric insulating gas of non-poison and nonflammable, and have a good arc suppression feature.
- Bushing diversity: Except for standard porcelain bushing, there are also provide various rubber bushing.
- 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.
- Fast operation: Used by spring stored energy operation system., make sure fast switch on and switch off operate ( no more than 1 second)
- Could provide controller: Stocked by electric controller, could operated in ground or operate by the main controller through RTU screen
- Solidity switch: Switch was made by solidity and anticorrosion material, make sure have a long useful life (30 years) have the pole equipment feature.
- Standard: it will filled full SF6 before delivery, and deal with seal. Test by IEC60265; GB3804.
