Indoor substations

With the growth of cities, new substations are increasingly being built in urban areas, which means size, silence and aesthetic appearance are becoming key considerations for these installations.

Hitachi Energy innovative technologies can shrink the size of an electrical substation by up to 70 percent and greatly minimize noise emissions. Accommodating all equipment required in an architecturally attractive multi-level building to match the surrounding cityscape frees valuable space for other usages. These innovative and proven solutions enable the most stringent requirements for power supply within urban areas to be fully met - compactness, economy, reliability and safety, all while allowing for easy maintenance access and future expansions.
