Mobile Substations

RHONA Mobile Substations

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 conditions of the client.
