HV PRODUCTS

Varcap & Varmatic HV

Varcap & Varmatic HV: A comprehensive range of low loss, environmentally friendly power capacitors, voltage range 660V - 33KV.

The capacitors can be supplied as loose units or finished assemblies.

The individual capacitors can be utilised to replace existing capacitors. The complete assemblies can be supplied as fixed or automatic banks which incorporate Vacuum/SF6 contactors.

A design service is available for individual customer requirements / harmonic filter banks.

The Varmatic HV assembly offers the latest technology in the supply of automatic capacitive reactive power combining very high quality components with state of the art engineering expertise.

RANGE OF EQUIPMENT

Varcap HV

All film dielectric, no PCB presence.

Losses less than 0.2W/KVAr.

Ratings 25KVAr - 400KVAr, single and 3 phase.

Stainless steel welded container.

Porcelain bushings.

Varmatic HV

Designed to specific site requirement.

Individual automatic stage sizes 50KVAr - 1000KVAr.

Assemblies in free standing sheet steel enclosure complete

with all control power supplies, HRC fuse protection, etc.

Harmonic Filters

Designed to specific site requirement.

Reactors can be iron/air cored or oil immersed.

On site commissioning.

Associated HV Switchgear

It is usual to supply the Varmatic range from an oil/SF6 fused

switch or circuit breaker, off the existing HV network.

We can check the suitability of existing switchgear, modify, overhaul and test.
