The Group defines its new vision with the strapline ‘We are a leading provider of high-class electrical infrastructure products in key markets around the globe’.


R&S increases its international reach with Tesar, a well-known transformers manufacturer operating in Italy, Poland and the Middle East. Founded in 1979 in Arezzo, the company adds innovative cast resin and instrument transformers to the R&S portfolio.


R&S further enhances its transformer portfolio with the acquisition of ZREW. The Polish company, founded 1956 in Łódź, provides high-class power transformers.

The acquisition of Rauscher & Stoecklin sets the first milestone of today’s R&S Group.
