Marine Dry-Type Transformer

ABB is the world market leader for marine transformers. Dry transformers (cast resin or VPI) are standard on ships — no oil cooling, no fire risk. On diesel-electric ships (cruise, LNG carriers) transformers for voltage conversion between generator (6.6/11kV) and consumers (440V) are essential.
