Outdoor AC High Voltage Isolate Switch - Electrical Switch
Introduction - AC High Voltage Isolate Switch
MZG13-12 Outdoor AC High Voltage Isolate Switch (hereinafter refers to the switch) is applied in 10kV high voltage transmission and distribution circuit to cut or close unload voltage single or three- phase circuit. It is used by the single phase of the three-phase system. It is simply structured, economical and convenient. Its rated currents are: 200, 400, and 600 and1000A. They all are composed by a chassis, support insulator, the conductive part and mechanical part. It adopts opening and closing switch structure to open and close the circuit. Each phase switch is composed by two pieces of conductive blade which is installed with compact spring in both sides. By adjusting the height of the spring, the needed contact pressure is attained. The insulation operation mechanism can make closing action when the switch is closed. The switch has self-lock devices.
Environmental Conditions - AC High Voltage Isolate Switch
1. Altitude: Lower than 1000m
2. Environmental temperature: -30°C~+40°C；
3. Outdoor wind speed: No more than 35m/s
4. Earthquake intensity < 8°
5. No gas, steam, and chemical properties deposition, filthy dust, and other explosive, etching medium which have serious impact on the conductive and insulating capacity of the switching
6. No frequent dramatic shake.
