Transformers and substations

As South Africa seeks to modernise its power infrastructure, ACTOM’s Engineering Projects and Contracts (EPC) Division is stepping to the forefront.

At Enlit 2025, ABB showcased some of its innovative solutions that support energy efficiency in industrial applications.

ACTOM, a leader in energy infrastructure, will launch its Data Centre Power Solutions at Enlit Africa 2025. As the data centre industry expands rapidly across the African continent, ACTOM is well-positioned to serve as a strategic partner to address the sector’s growing demand for reliable and sustainable energy solutions.

The high-performance cross-linked polyethylene (XLPE) material is the most common insulation used in medium voltage (MV) cables, from 6.6 kV to 33 kV, mainly because of its mechanical and electrical properties. However, the properties of XLPE are significantly affected if the material is exposed to water and moisture, resulting in water trees.

For a data centre in the Netherlands, TMC Transformers has designed, manufactured and installed dry-type transformers for a large intake substation. Managing Director of Trafo Power Solutions, David Claassen explains the significance of this pioneering project.
