Our K series switchgear can be divided into two types: fixed type and unit-combination extendable type. With perfect corrosion resistant enclosure and sealing, it can be used in various places.
It is widely used in 3-24kv power distribution network, such as indoor/outdoor switch station, box-type transformer substation, residence district, business center, buildings.
Features:
-SF6 gas pressure:under 20°C 1.4bar(absolute pressure)
-SF6 gas annual leakage rate:1‰
-Water immersion test: apply 0.3 bar pressure under water /24 hours
-Arc test: with arc extinguisher 20KA/1S, without arc extinguisher 16KA/1S
-free of maintenance for 30 years
-It is not affected by environment: anti-condensation,anti-frost,anti-salt mist,anti-filthy,anti-corrosion,UV-resistance,and chemicals resistance. It can be used in poor environment.
K series can also be called:
SF6 ring main unit(RMU)
gas insulated switchgear(GIS)
ring main unit switchgear, switchgear
