Open -Stack Substation Capacitor Bank

Shreem's open-stack shunt capacitor banks offer an economical way to apply large blocks of three-phase reactive power (kVAr) to a power system. Capacitor units are single phase, all film dielectric and connected for three phase operation. Racks are factory assembled from galvanized steel or aluminum for strong support and maximum resistance to corrosion. A complete line of accessories is available for customizing designs in order to meet specific requirements. Shreem offers reliable protection utilizing externally fused, fuseless, or internally fused technology to suit the most demanding application. These banks meet the applicable ANSI/IEEE, CSA, or IEC standards, In addition, Shreem's quality system is certified ISO 9001.
