The Tesar Group, headquartered in Subbiano, Italy, with additional production sites in Poland and the United Arab Emirates, has been developing and manufacturing high-quality cast resin transformers as well as current and voltage transformers for over 40 years. As the first Italian company – and one of the pioneers in Europe – Tesar successfully introduced the technology of cast resin dry-type transformers as early as 1979, with now over 100,000 transformers installed worldwide. Tesar Italia is actively represented in European and international standardisation committees and works closely with utilities and operators – from special solutions for the lagoon city of Venice (“acqua alta”-resistant transformers) to major projects such as the stadiums of the FIFA World Cup 2022 in Qatar.

Certified management systems (ISO 9001, ISO 14001, ISO 45001) and modern manufacturing and testing facilities ensure consistently high product quality – “Italian engineering” for projects worldwide.

Since 2016, this long-established company has been part of the internationally successful R&S Group, a leading provider of electrical infrastructure products in key markets around the globe. The customer base ranges from renewable energy producers (wind and solar farms) and regional and supra-regional transmission and distribution network operators to customers in a wide variety of industrial and infrastructure sectors – including planners and operators of data centres, railway power supply systems, chemical and manufacturing plants, major hospitals, airports, metro and tramway systems as well as charging infrastructure for electromobility and many more.
