Hitachi announces new 25kV traction transformer

2022-9-22 Hitachi Energy

Hitachi Energy has announced the launch of its innovative oil-free traction transformer RESIBLOC^® Rail, with integrated cooling system and voltages up to 25-kilovolt (kV), at InnoTrans, the international trade fair for rail transportation at the Berlin Messe in Germany happening from September 20-23, 2022.

This plug-and-play solution is a breakthrough technology for dry-type on-board traction transformers. By integrating an efficient cooling system, Hitachi Energy significantly reduces installation complexity for train manufacturers while retaining the benefits of dry-type transformers.

In 2018, Hitachi Energy officially launched its flagship dry-type traction transformer: RESIBLOC^® Rail with voltages up to 15 kV. Since then, the technology has evolved, and its voltage rating has increased up to 25 kV.

Hitachi Energy has now further enhanced the capabilities of this technology and is introducing RESIBLOC^® Rail up to 25 kV with integrated cooling system. This traction transformer comes with a factory-fitted cooling system that is integrated with the design of the traction transformer, thus offering a never-before possibility of a plug-and-play solution of dry-type traction transformer to the customer.

“Dry-type transformers offer unmatched protection to people, property and the surrounding environment,” said Bruno Melles, Managing Director of Transformers Business Unit at Hitachi Energy. “This pioneering RESIBLOC^® Rail transformer technology developed by our world-class engineers will help accelerate a sustainable energy future for societies and the rail industry,” he added.
