Breakthrough oil-free traction transformer with integrated cooling system

Watch the RESIBLOC® Rail video on LinkedIn

RESIBLOC® dry-type transformers by Hitachi Energy have been relied upon by customers for more than 40 years. This technology has been deployed in highly demanding applications such as marine vessels, offshore oil & gas, underground mining, and many other extreme environments. RESIBLOC® transformers are known and utilized for their incredible strength, durability, and high performance. 

Hitachi Energy has successfully brought this safe and trusted technology to the world of traction propulsion systems by introducing RESIBLOC® Rail. After the successful launch of RESIBLOC® Rail in 2012 with 6.5 kV, Hitachi Energy upscaled this technology in 2021 to offer RESIBLOC® Rail up to 25 kV. 

With over 100 years of pioneering leadership in Traction Transformers and with more than 30,000 units currently in operation across the world, Hitachi Energy is well aware of the customers' challenges.

RESIBLOC® Rail with integrated cooling

With a vision of supporting customers to design and operate safe, reliable, and efficient trains, Hitachi Energy has further enhanced the trusted Resibloc Rail technology.

RESIBLOC® Rail is now the first dry-type, traction transformer with an integrated cooling system!  It is a unique breakthrough technology of plug-and-play, dry-type traction transformers that can significantly reduce installation complexity for the train manufacturers while retaining the benefits of dry-type transformers. In effect, reducing the total cost of ownership. RESIBLOC® Rail with integrated cooling is available up to 25 kV. 

Why choose RESIBLOC® Rail, dry-type, traction transformers
