High Voltage Installation and Maintenance up to 11kV

HV (High Voltage) is classed as any three phase electrical switchgear with voltage ratings from 1 kV alternating current (AC) up to and including 33 kV (AC). This includes circuit-breakers, switches, switch fuses, isolators and high-voltage (HV) contactors that use oil, air, sulphur hexafluoride (SF6) or vacuum as the interrupting medium.

Failure of any electrical switchgear can cause death, serious injury and major damage. If your premises have HV switchgear that you own or operate it is important that the system is properly maintained and serviced to help reduce the risk of accidents.
