Product information

Gas-insulated medium-voltage switchgear for primary distribution

The factory-assembled, type-tested Siemens NXPLUS C fixed circuit-breaker switchgear for indoor installation is a particularly versatile metal-enclosed, gas-insulated medium-voltage switchgear with metallic partitions that enables flexible system design. Available for single-busbar as well as double-busbar applications, NXPLUS C gas-insulated switchgear is used in transformer and switching substations in a vast range of power supply applications. Siemens NXPLUS C circuit-breaker switchgear is also suited for marine applications on ships and platforms, since it has been type-approved by all relevant classification societies. The specially designed NXPLUS C Wind model has been adapted to the requirements of onshore and offshore wind turbines.
