At a time of growing cost and performance pressure it is even more important to decide on the right technology, above all because switchgear represents an investment for the next decades.
Compactness, performance, climatic independence and cost efficiency add to the central aspects of gas-insulated medium-voltage switchgear from Siemens in order to provide a future-proof investment: optimal personal and functional safety, as well as reliable, maintenance-free operation.
