drawoutmetal-clad and metal-enclosed switchgear cubicle is suitable for single-bus and thesingle-bus power system of threephase AC 50HZ, 35KV. And it mainly used in thepower plants, substation, industrial and mining enterprises, high buildings to receive and distribute power, and monitor control and protect ofthe circuit. It complies with the standard of IEC60298, GB3906, and DL404 andhas the perfected “five defense” system.
It is with the withdrawout ZN8540.5 (3AV3) vacuum circuit breakeror SF type of SP series of SF6 circuit breaker. It applies the heat shrinkableinsulating material and epoxy coating insulating technology. The optimizedelectrode shape makes the structure compacted, small sized. The cabinet appliesthe high-quality aluminum-zinc alloy steel sheet, processed by NC, connected byhigh-intensity bolts, nut and rivet nut; the surface applies the mining sprayor galvanized process. The cubicles are isolated by metal clapboard with uniquepressure channel.
