Tesar Information

Located in Subbiano – Arezzo Italy, Tesar has been designing and manufacturing cast resin transformers for more than 40 years. The company was established in 1979 and was the first Italian company to implement the technique of resin casting for transformers. After a few successful business years, the company decided to expand its portfolio to include oil-immersed and instrument transformers. Given the strategic importance of the Middle East, in 2007 Tesar opened its own representative office in Dubai to improve its local presence in the Gulf countries. In September 2012, Tesar set up the JV company Tesar Gulf together with a local partner and established a new production site in Al Ain to supply the discerning Abu Dhabi market. After many years operating with a sales office in Poland, the company decided to build a new manufacturing facility by the green field in the industrial area of Kraków; it has been up and running since 2013. In 2016, Tesar became part of R&S, a leading provider of electrical infrastructure products in key markets around the globe
