Capacitors

Spectrum Industries offers a comprehensive range of high-voltage capacitors and capacitor banks, engineered to deliver power-factor correction, voltage support, and reactive-power compensation across utility distribution, transmission, and industrial power systems. Our lineup includes individual shunt capacitor units, HV surge capacitors, distribution pole-top banks, open-rack shunt capacitor banks, metal-enclosed bank assemblies, and series compensation systems for long transmission corridors. Every capacitor is built with a time-proven all-film, folded-foil dielectric and Dielektrol® VIIa non-PCB insulating fluid, hermetically sealed for reliable long-term service in indoor and outdoor environments.

Available in Standard and Heavy Duty stress ratings from 25 kVAR through 600 MVAR at voltages from 2.4 kV to 765 kV, our capacitors and banks meet or exceed the latest revisions of IEC 60871 and IEEE 18, with 100% electrical testing and triple leak testing on every unit. Whether the application is bulk transmission VAR support, distribution feeder correction, harmonic-filter tuning, or transient overvoltage protection at generator and motor terminals, Spectrum's capacitor solutions deliver dependable performance and long service life across the most demanding operating conditions. Easy to specify and integrate, they arrive fully tested and backed by Spectrum's commitment to quality and customer support.

Choose Spectrum Industries for precision-engineered capacitors and capacitor banks that keep your power systems balanced, efficient, and reliable.
