ACTOM High Voltage Equipment develops composite insulators for instrument transformers

ACTOM High Voltage Equipment has developed a composite insulator for its 132 kV instrument transformers, following its successful introduction of an ACTOM-branded composite post insulator for its 132 kV disconnectors in early-2014.

The division’s move to develop composite insulators was prompted mainly by the need to provide insulators with improved pollution performance, which silicon insulators provide.

The latest ACTOM-branded offerings are for the division’s 132 kV current and voltage transformers. As with the porcelain-core insulators for its 132 kV disconnectors introduced earlier in 2014, these glass-core composite insulators are designed and manufactured according to global best practice.

Terry Lawrenson, ACTOM High Voltage Equipment’s Divisional CEO, said the ACTOM-branded insulators have been developed in response to customer demand.  “We are progressively developing our own designs of insulators for our equipment with the goal of offering our markets the options they prefer when it comes to insulators, eventually supplying all the various types of high voltage equipment we manufacture fitted with ACTOM-branded silicon-coated composite insulators specifically designed to suit each type,” he explained.

“In addition to the silicon insulators for protection against pollution, the new product has the advantage that it is less subject to damage than the conventional product,” Lawrenson added.

The division is on track to also introduce silicon-coated composite insulators for its 11 kV, 22 kV and 33 kV instrument transformers.

ACTOM (Pty) Ltd is the largest manufacturer, solution provider, repairer and distributor of electro-mechanical equipment in Africa, offering a winning and balanced combination of manufacturing, service, repairs, projects and distribution through its 41 distribution outlets throughout Southern Africa.

ACTOM is also a major local supplier of electrical equipment, services and balance of plant to the renewable energy projects.

It also holds numerous technology, distribution and value added reseller agreements with various partners, both locally and internationally.
