ABB dry-type transformers

The EcoDry low-loss transformer, TriDry triangular transformer and PoleDry transformers can provide improved efficiency, safety and eco-compatibility for utility, oil and gas, and mining industries.

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

The TriDry transformer 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 2500 kVA.

EcoDry dry-type distribution transformers provide the inherent benefits of a dry-type transformer, including fire safety and environmental friendliness (no fluid leakage) with high efficiencies to provide a solution for renewable energy applications. EcoDry transformers incorporate amorphous-metal core lamination which reduces transformer losses up to 70%. The EcoDryBasic dry-type transformer is for distribution transformers with a low average load and the EcoDry99Plus is suitable for applications involving a high to very high loading.
