Breakthrough oil-free traction transformer launched by ABB

ABB announced the launch of its breakthrough oil-free traction transformer to be used in rail transport.

According to ABB, first of its kind oil-free dry-type traction transformer achieves new level of safety and uses epoxy insulation and glass fiber to give it “unsurpassed mechanical strength”.

The RESIBLOC® Rail oil-free transformer reaches a record efficiency rate of 97 percent. Compared to traditional transformers it can reduce overall operational energy costs by up to 10 percent.

Such transformers feed power to essential train functions like traction, lighting, heating and ventilation, brakes, signaling and communication. Traction transformers are a critical link in the traction chain, driving train performance and operator services.
