With adoption of a new type of insulated design and vacuum arc extinguish chamber, the load switch has visible fracture when breaking, therefore it has the function of isolation switch. With large breaking capacity and oil-free function, it has environmental friendly, no risk of explo-sion, long mechanical lifespan and maintenance free character-istics

vacuum arc extinguish chamber and the insulating sleeve are covered by insulation silicone grease to meet the outdoor use. The vacuum arc extinguish chamber circuits the moment when switches is breaking or closing. Its normal working current is turned on by the isolation blade. When opening, the rotation of the spindle by mechanism, drives the switch tripping, the main circuit is totally separated, wherein, the main circuit has visible isolation fracture after being separated. As the adoption of vac-uum switch tube arc, the load switch has characteristics of large closing capacity, good arc extinguishing effect, high reliability and environmental friendly, no explosion danger, long mechani-cal life and free maintenance.

Normal Working Environment

swith has two knob insulators installed on the bearing, connected with connecting-rod (GW4-10 series disconnecting switch has only one knob insulator installed on the bearing, and the other one fixed on the other side). It can circumgyrate horizon-tally. GW4 series disconnecting switch conduction switch blade separated to two parts is fixed on two knob insulators, and make switch on/off horizontally. The contacting position of contact is on the middle between two knob insulators. When using operating mechanism and tum electric conductor 91o, the other knob insu-lator and electric conductor will also turn 91° (when the operat-ing mechanism of the GW4-10 series disconnecting switch work, only the knob insulator installed on base bearing and electric conductor turn 91o, the other will be fixed). So the switch blade will switch on/off alone to the same direction.
