Maschinenfabrik Reinhausen (MR)

Maschinenfabrik Reinhausen GmbH (MR) is the core company of the Reinhausen Group, founded in 1868 in the city of Regensburg. The group also includes 38 subsidiaries and 6 affiliated companies located worldwide.

The company’s primary focus is the development and manufacturing of equipment for regulating power transformers. Regulation is carried out using on-load tap changers (OLTCs), which adjust the transformation ratio according to load conditions. In combination with other MR products and services, these solutions ensure stable and reliable power supply.

With the continuous growth of electrical network loads, the importance of voltage regulation systems is steadily increasing. In response, the company offers advanced and innovative solutions. Its portfolio of voltage control technologies is complemented by the design of reactive power compensation systems, as well as related services such as network analysis and parameter calculations.

Another area of activity is the production of insulation cylinders made of epoxy resin reinforced with fiberglass, along with their further processing and the manufacturing of composite hollow insulators.

Today, more than 50% of the world’s generated electrical energy passes through equipment produced by the company. A strong commitment to innovation, expertise, and reliability across all operations forms the foundation for effective cooperation and delivers tangible benefits to customers.
