Typical uses, ratings Typical uses Fixed-mounted circuit-breaker switchgear NXPLUS C is a factory-assembled, type-tested, metal-enclosed, SF6-insulated switchgear with metallic partitions 3) for single-busbar and double-busbar applications for indoor installation. It is used in transformer and switching substations, e.g., in: • Power supply companies • Power stations • Cement industry • Automobile industry • Iron and steel works • Rolling mills • Mining industry • Textile, paper and food industries • Chemical industry • Petroleum industry • Pipeline installations • Offshore installations •...

Features Safety Environmental independence Hermetically tight, welded switchgear vessels made of stainless steel as well as single-pole solid insulation make the parts of the primary circuit under high voltage of NXPLUS C switchgear • nsensitive to certain aggressive ambient conditions, I such as saline air, air humidity, dust and condensation • Tight to ingress of foreign objects, such as dust, p ollution, small animals, humidity • Independent of the site altitude. This high degree of environmental independence cannot be achieved for the air-insulated metering panel due to the partial air...
