Siemens to Provide New Switchgear Technology for National Grid Substation Project

National Grid chose Siemens to provide its 63 kA arc-resistant switchgear technology for the utility's new electric substation in downtown Providence, Rhode Island. Siemens' 63 kA type GM-SG-AR switchgear is designed to improve power reliability and includes arc-resistant features that increase safety conditions for workers and operators. The technology's design will also allow National Grid and contractor TRC Companies to reduce the project's physical footprint.
