Product Description
1.General Description
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 compact, reliable and safe. It is an intelligent switchgear that combines industrial automatic technology.
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.
2.Technical 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.
