GW1 outdoor AC high voltage isolation switch is suitable for installation on the line of outdoor high voltage power distribution equipment for the purpose of cutting off the line and converting the line when the line has voltage and no load. This product is a three-phase electrical appliance consisting of three separate single-pole isolating switches. Each single-pole isolating switch has the same components, such as base pillar insulator, front and rear static contacts, knife and arc angle, etc.
Environmental conditions:
1. The altitude should not exceed 2000m.
2. The upper limit of ambient temperature is +40℃, and the lower limit is -30℃ in general areas.
3. The wind pressure does not exceed 8 degrees.
4. The earthquake intensity does not exceed 8 degrees.
5. The thickness of ice coating is not more than 1mm.
6. There is no frequent violent vibration in the installation site.
7. Gas, steam, chemical deposits, salt spray, dust and other explosive and corrosive substances that seriously affect the insulation and conductive fertility of the isolating switch should be installed in ordinary installation sites.
8. The anti-fouling type is suitable for heavily polluted areas, but should not be used to cause superfluous fire and explosion.
