Outdoor AC High Voltage Isolate Switch [Vacuum Circuit Breaker]
Introduction - AC High Voltage Isolate Switch [Vacuum Circuit Breaker]GW9-10/15 Outdoor AC Single Electrode Isolate Switch (hereinafter refers to the switch) applies to 10kV high voltage power supply and distribution circuit. It is used to cut and close unload single or three-phase circuits. It is used by one single phase of the three-phase system. It has simple structure. It is economical and convenient. The rated current of the switch are: 200,400, 600 and 1000 A. They are composed of chassis, insulator support, conductive part and mechanical parts. It adopts switch structure which cuts and closes the circuit. Each switch is composed of two pieces of conductive blades, which are configured with compact spring. By adjusting the spring’s height, the needed contact pressure of the switch can be attained. When the switch opens or closes, it can be closed by the insulate operation mechanism. The switch has self-lock device.
Working & Environmental Conditions - AC High Voltage Isolate Switch
1. Altitude lower than 1000m
2. Environmental humidity: maximum less than +40°C,minimum higher than -30°C
3. Outdoor wind speed slower than 35m/s
4. Earthquake intensity smaller than 8 degree.
5. 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.
6. No regular dramatic shake
