The ABB capacitor unit type HiQ is designed for heavy-duty operation in Shunt, Harmonic Filter, Series Capacitor, SVC and HVDC applications in all climatic conditions. More than 150 000 units have been successfully supplied all over the world in the last decade.

HiQ is a single-phase power capacitor of all film type, with very low dielectric losses and long lifetime. The capacitors are impregnated with a bio-degradable, non-PCB fluid with a high insulation strength. The edges of the electrode foils are folded, enabling higher electrical stress. The ABB capacitor units have an extremely low failure rate and high reliability. HiQ capacitor units are available with Internal or External Fuses or Fuseless.
