Transformers for Data Centers

We secure reliable power for your data center, offering a complete range of liquid-filled and dry-type transformers, as well as services, so that a sustainable future is in your control.

From transformers for primary power supply for utility grids to secondary units in substations, Hitachi Energy technology helps increase the reliability and improve the operations of data centers while reducing life cycle cost and environmental impact.​

We are ready to grow together

Hyperscale

As organizations process and manage vast amounts of data, hyperscale data centers have not only expanded in size and compute power, but their resulting emissions have also increased.

These large-scale facilities not only need scalability to be able to expand and evolve in-line with changing requirements but require sustainable and customizable solutions that work to prevent outages, reduce environmental impact, and ensure reliability and profitability.

Colocation

The rapid increase in reliance upon data centers is placing additional pressure on colocation centers as they seek to expand their footprint and operations quickly and efficiently.

Colocation owners, managers, and engineers require modular, repeatable designs that not only enable rapid expansion and fast deployment, but that also minimize costs and maximize uptime – all while protecting your operations with greater data protection and cybersecurity.
