The HV6 range of equipment is used on networks of 7.2kV and below and has short circuit levels of up to 40kA. The contactors are rated at 6.6/7.2kV, 400A. Whilst the range was introduced in the late 1970’s, there are still many units providing very reliable service to their owners.
The HV6 units were generally employed for motor starting duties, where frequent operation was prevalent. Whilst there are no operational or service issues with the HV6 switchgear, all equipment that is frequently operated has a finite life due to general wear and tear of components.
The HV6 switchgear generally formed part of a composite switchboard with incoming circuit breakers/bus section breakers from the VSI, VV (Vactruck) or the VMV ranges of switchgear. Freestanding units, dedicated HV6 switchboards or specific motor starter arrangements such as auto transformer/Korndorffer starters were also commonplace.
