And it mainly used in the power plants, substation, industrial and mining enterprises, high-rise buildings to receive and distribute power, and monitor control and protect of the circuit. It complies with the standard of IEC60298, GB3906, and DL404 and has the perfected "five defense" system.It is with the withdrawout ZN85-40.5 (3AV3) vacuum circuit breaker or SF type of SP series of SF6 circuit breaker. It applies the heat shrinkable insulating material and epoxy coating insulating technology. The optimized electrode shape makes the structure compacted, small sized. The cabinet applies the high-quality aluminum-zinc alloy steel sheet, processed by NC, connected by high-intensity bolts, nut and rivet nut; the surface applies the mining spray or galvanized process. The cubicles are isolated by metal clapboard with unique pressure channel.Kyn three phase low voltage electrical switch cabi SWF79.pdf
