We at Hivolt Capacitors Limited have been designing and manufacturing high voltage capacitors at our factory in Northern Ireland since 1968.

In the manufacture of our product we employ mixed dielectric technology. Our impregnant is a highely refined pure mineral oil. We do not use PCB’s or other toxic material. Typical applications for our capacitors include X-ray power supplies, linear accelerators, laser, radar and pulse equipment, RF transmitters, railway traction and general high voltage power supplies.
