Dedicated switching surge protection, from Australia and beyond

Every year, medium-voltage motors and dry-type transformers fail because of steep-fronted switching surges, especially on systems switched by vacuum, SF6 or metal-vapour breakers and contactors. A single insulation failure can mean days of lost production.

Access T&D has spent over 25 years helping utilities, engineering firms and mining operations in Australia and beyond prevent those failures. We are an authorised reseller of ZORC and PROTEC Z surge suppressors and Strike Technologies protection relays, with direct support from the manufacturers.
