Transformers and substations

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.

Last year, ABB delivered solutions for three substations in Uganda run by the country's leading utility, Umeme Limited (UMEME). The utility manages and operates the state-owned and leased electricity distribution network assets.

Doble RTS™ (RTS) is a leading protection testing software system to improve the testing of relays and manage test records. The RTS software is distinguished by the process consistency it delivers with power and flexibility – and automation enables unmatched efficiency, accuracy and productivity.

Founded as a specialist in dry-type transformers, Trafo Power Solutions has expanded its vision to become a leading provider of electrical power solutions in Africa. Managing Director, David Claassen explains how the company has leveraged its depth of expertise and growing reputation across many sectors to extend its range of offerings.
