Pre­mier cen­ter of excel­lence for high-vol­ta­ge insulation

EXPERTS FOR YOUR SUC­CESS

Our com­pe­tence cen­ter for high-vol­ta­ge insu­la­ti­on of rota­ting machine­ry is one of the worl­d’s lea­ding insti­tu­tes. It spe­cia­li­zes in the deve­lo­p­ment of electri­cal insu­la­ti­on sys­tems for motors, gene­ra­tors and transformers.

As part of our group­wi­de pro­duct deve­lo­p­ment, the insti­tu­te plays an important role in the design, qua­li­fi­ca­ti­on and long-term tes­ting for new pro­ducts. As an inno­va­ti­on part­ner, we sup­port lea­ding manu­fac­tu­rers in exter­nal pro­jects to deve­lop cus­to­mi­zed insu­la­ti­on systems.

A coope­ra­ti­on with us gives you access to our expe­ri­ence and know­ledge from over one hund­red years.
