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 highly refined pure mineral oil. We do not use PCBs 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. A range of pulse-forming networks and high-voltage rectifiers are also manufactured.

At Hivolt Capacitors Limited we specialise in the manufacture of custom built components. We produce small batch quantities and can supply on a one-off basis replacements for those difficult to source capacitors. Our flexible design approach has enabled us to become the leading UK producer of capacitors for almost every high voltage application.

The name of Hivolt Capacitors Limited has become synonymous with quality for both product and efficiency of service. Our commitment to quality has been officially recognised since 1991 when we were awarded the International Standard Quality Certificate BS EN ISO 9002.  In November 2003 our certification was upgraded to ISO 9001 : 2000. In February 2003 the company achieved certification to BSEN ISO 14001 the International Standard for Environmental Management Systems. This reflects the company's commitment to caring for the world we live in. We ensure these standards are maintained by having audits carried out by external bodies.

Over the years Hivolt Capacitors Limited has built an impressive loyal customer base. Our market which was once mainly located in the UK and Europe now stretches from the USA to Australia, Scandinavia to South Africa and more recently to Taiwan and Japan.

We look forward to expanding this customer base and satisfying any capacitor requirements you may have.
