Modular substations

The key component in the concept is the VEO E-House, a modular substation building. VEO E-House modules are prefabricated, fitted, and internally wired with the needed substation equipment such as AC/DC systems, control, protection and communication equipment and medium-voltage switchgears. The fitted modules are tested in controlled conditions at VEO’s factory. When shipped off to site, the substation building contains everything from medium-voltage switchgear to control and communication equipment, fire and burglar systems as well as lighting and heating. In addition, the VEO E-house can be equipped with optional features such as charging stations for electric vehicles, solar roofs or alternative colours and materials for exterior wall coating.

While the VEO E-House modules are prefabricated, preinstalled and tested at the factory, civil works and mechanical installations of outdoor components can be conducted at site at the same time. Thanks to simultaneous progress at the factory and at the site, the overall time at site and overlapping work phases are minimised. This is a key factor in keeping personal safety at excellent levels as it means reduced working time in close proximity to machinery and live equipment.

The substations can be delivered based on air-insulated or gas-insulated switchgear technology or a combination of both. The projects are managed by our experienced project management team, and our inhouse engineering team is responsible for the mechanical and electrical engineering as well as the testing and commissioning of the substations.

The VEO E-House is dimensioned to house control, protection and communication equipment and switchgears up to 45kV, according to client configurations and needs. The lifespan of the buildings is approximately 50 years.
