RHONA’s Mobile Substations are designed as compact, transportable solutions that enable fast and flexible power deployment for a wide range of industrial and utility applications. These turnkey systems integrate key substation components—such as power transformers, medium- voltage switchgear, and protection systems—mounted on trailers or skid platforms, allowing rapid mobilization and installation.
Our mobile substations are ideal for temporary energy supply, emergency response, maintenance operations, and fast-tracked infrastructure projects. Each system is engineered to meet the specific technical, dimensional, and environmental requirements of the client.
