CompactStar™ Power Transformers
More power, smaller footprint
CompactStar™ - A premium, compact, and lightweight transformer optimized for the Total Ownership Cost (TOC) of offshore substations and a perfect-fit solution for urban substations.
CompactStar™ combines Hitachi Energy's global leadership and transformer expertise with innovative design and premium materials that have enhanced thermal performance, making it a smart investment for customers looking to reduce TOC and improve operational safety.
CompactStar™ is optimized for space-saving and weight reduction without compromising on performance. It is up to 30% smaller in size and weight compared to conventional transformers, making it a perfect-fit solution for space-constrained areas. It also reduces the structural costs of the offshore platform, allowing for more efficient use of space.
Despite its smaller size, CompactStar™ provides high-capacity output, making it an ideal solution for meeting increasing renewable energy demands. It can provide up to 30% more capacity than conventional transformers in the same space.
CompactStar™ uses Ester fluids for cooling optimization, which offers increased operational safety for people and the environment.
