Type NXPLUS C (up to 24 kV) Gas-Insulated Switchgear
Description
Description
Increased personnel safety, low-maintenance, compact, robust: gas-insulated medium-voltage switchgear type NXPLUS C from Siemens provides a reliable solution, even under extreme conditions.
A unique, sealed-for-life, hermetically laser-welded, stainless steel pressure vessel with vacuum switching technology and a digital protection system makes the type NXPLUS C switchgear independent from most industrial contamination conditions and most extreme climatic conditions, resulting in low maintenance and longer product life cycle. On top of that, the SF6 insulation enables an extremely compact construction that helps to optimize space requirements in buildings.
The result: lower installation cost, minimum operating costs, maximum performance and high reliability.
Type NXPLUS C offers a flexible product range in panel designs for an efficient cost solution for each application.
