ABB announced the Australian launch of three new dry-type transformers at Automation and Power World Australia 2012 held on the Gold Coast.

The new improved EcoDry low-loss transformer, Tridry triangular transformer and Poledry transformers offer customers improved efficiency, safety and eco-compatibility and meet the most stringent of customer specifications.

PoleDry transformer: The PoleDry transformer is ABB’s first ever dry-type (no fluid inside) transformer designed for pole-mounted applications and is the safest transformer for people, property and the environment in overhead distribution. The transformer is manufactured using ABB’s Vacuum Cast Coil (VCC) technology ensuring the PoleDry transformer is non-flammable and self-extinguishing.

Tridry transformer: The TriDry adopts ABB’s latest core technology, using a triangular construction for its core. Along with the traditional advantages offered by a dry-type transformer, the symmetrical construction ensures that no-load losses, footprint, weight, noise emissions, inrush currents, harmonic content and stray magnetic fields are all reduced. This compact, efficient and safe transformer range extends from 100 to 2500kVA. It is a product range through which ABB makes a meaningful contribution towards enhanced eco-compatibility and climate protection.

EcoDry transformer: EcoDry dry-type distribution transformers are “green” transformers which provide the inherent benefits of a dry-type transformer, including fire safety and environmental friendliness (no fluid leakage) with ultra high efficiencies to provide a unique solution for renewable energy applications. EcoDry transformers incorporate amorphous-metal core lamination which reduces transformer losses up to 70%. To match individual customer applications, ABB offers different types of EcoDry, utilising different technologies for efficiency optimisation: the EcoDryBasic dry-type transformer for distribution transformers with a low average load, and the EcoDry99Plus for applications involving a high to very high loading.

In addition to the dry-type range, ABB will showcase recent improvements to the oil-filled transformer manufacturing processes and environmentally friendly insulating fluid, BIOTEMP which highlights ABB’s commitment to safety and the environment.
