GN24-12 model indoor HV disconnect switch applies to power system of rated voltage 12KV, AC 50Hz, it is used to break and make circuit under no-load. there are additional pollution abatement type, high altitude type and electrified display.
This series of isolation switches is a three-pole type and consists of a chassis, a shaft, a lever, a porcelain pillar insulator, a knife and a terminal board. The shaft is placed on the base frame, and three pairs of levers are welded on the shaft. The lever is made of a porcelain insulator and a knife necklace. The shaft protrudes from the base frame, any of which can be connected to the operating mechanism.
1.The altitude: 1000m~3000m
2.The ambient temperature: -30°C~40°C
