As a trusted integrated solution supplier to the worlds leading transformer manufactures, we offer a complete range of products for use in the power transformer sector.

Distribution Transformers

Distribution transformers are high in volume, can vary greatly depending on the application, and often provide the last step between the network and end consumer.  They require high levels of reliability and efficiency, with the flexibility to provide consumers with a high quality supply, often within the most challenging environmental and technical parameters. Weidmann is a trusted supplier to the distribution market, involved in a wide range of activities across our full product and services portfolio.

Instrument Transformers

Transforming voltage and currents into measureable values, instrument transformers are relied upon for safe and efficient operation of the electricity network. Required to provide highly accurate data in order to protect and verify revenues, instrument transformers are expected to be highly reliable and operate without fault, often for more than 25 years.  Weidmann has long been a trusted supplier to instrument transformer manufacturers around the world.

Renewables

In recent years it is clear that renewable energy is no longer considered ‘alternative’ but rather a key part of our energy generation system. Whether in the generation plant itself, or connection of renewable plants into the grid, new challenges are faced on a regular basis. Weidmann has a range of solutions to support the renewable energy sector, whether it relates to a compact transformer design using our Weidmann Knowledge Services and Insulation Technology, or the need to better understand the performance of assets with Monitoring and Diagnostics, Weidmann has a solution.

Traction Transformers

With additional complexities often related to size and fluctuating loads, transformers supplied to the railway industry require special attention. Collaborating with DuPont, Weidmann are the leading supplier of Nomex® high temperature thermal insulating technology for traction transformers. Working with the largest suppliers of transportation solutions in the world, our insulation technology and Weidmann Knowledge Services Traction specialists work to ensure mass transportation achieves high levels of efficiency and reliability, while meeting global regulations.
