Open Stack Rack Equipment

Open Stack Rack Capacitor Banks are most applicable where large blocks of three-phase kilovar are required. Capacitors and auxiliary equipment are installed in welded aluminum racks. Racks are shipped ready for field installation including base and inter-rack insulators, substructures, interconnecting bus wire and other specified accessories for a complete three phase system. General Electric offers three primary types of open stack rack equipment: externally fused, internally fused and fuseless, each with its own unique set of advantages and limitations. Our engineering staff can help choose the design that best fits your specific requirements. Harmonic filters are also available. Available open rack outdoor Harmonic Filter Banks should be considered when power factor correction is desired in a harmonic environment.
