MZG13-12 outdoor single pole isolation switch (hereinafter referred to as the switch) is suitable for 10kV high-voltage transmission and distribution lines, used to cut off and close single-phase or three-phase circuits with no load and voltage. The switch is designed for single-phase use in three-phase systems, and its structure is simple, economical, and easy to use. The rated current of the switch is 200; 400； 600 and 1000A. They are both composed of a base, post insulators, conductive parts, and mechanism parts. Adopting a knife type structure to open and close the circuit. Each phase switch blade is composed of two conductive blades, and compression springs are installed on both sides of the blades. Adjusting the height of the springs can obtain the contact pressure required for the switch blade. The insulation operating mechanism can be used to perform closing movement when opening and closing the switch. The knife switch has a self-locking device.

Structural features:
1. Altitude not exceeding 1000m;
2. Environmental humidity: The maximum environmental humidity shall not exceed+40 ℃, and the minimum environmental humidity shall not be lower than -30 ℃;
3. Outdoor wind speed not exceeding 35m/s;
4. The seismic intensity shall not exceed 8 degrees;
5. The installation site should be free of gases, vapors, chemical deposits, dust, dirt, and other explosive or corrosive media that seriously affect the insulation and conductivity of the switch;
6. The installation site should be free from frequent and severe vibrations.
