Outdoor AC High Voltage Isolate Switch - Vacuum Circuit Breaker
Introduction - AC High Voltage Isolate Switch [Vacuum Circuit Breaker]GW1-12G(D)Series Outdoor High Voltage Isolate Switch is aHigh Voltage Electric Componentsequipment of single phase structure. It is used in unload outdoor 12kV circuit network to open and close the circuit. It has the ground knife and configures cs mouth type manual operation mechanism which can prevent misuse of the charged ground wire when closing the switch. The operators do not need hang any other ground wire.
Filthy-proof outdoor high voltage isolate switch can satisfy the requirements of seriously polluted areas and can effectively solve the pollution problems during the isolate switch operation.
Working & Environmental Conditions - AC High Voltage Isolate Switch
1. Altitude 1000-3000m
2. Environmental temperatures: maximum +40°C, minimum:-30°C (general), -40°C (alpine region)
3. Wind pressure smaller than8 degree
4. Earthquake intensity smaller than 8 degree.
5. No regular dramatic shake
6. General type: no things which seriously affect the insulation and conductive ability of the switch, such as gas, steam, chemical deposit, dust and other explosive immersed corrosion medium.
7.Filthy-proof types are applied to seriously polluted regions. There should be no flammable or explosive objects.
