Double-column isolating switch: with two insulating pillars, the structure is relatively stable.
Classification by installation method:
Outdoor isolation switch: can withstand wind, rain, snow, dirt, condensation, ice and frost, suitable for installation in the terrace.
Indoor high-voltage isolation switch: installed in the indoor environment, used for high-voltage power system isolation.
Classification by insulation pillar structure:
Single-column isolating switch: The vertical space is directly used as the electrical insulation of the fracture under the overhead bus, saving floor space and reducing lead wires.
Double-column isolating switch: with two insulating pillars, the structure is relatively stable.
Three-post disconnector: It has three insulating pillars and is usually used in power systems with higher voltage levels.
