Your partner for high-voltage insulation in rotating machinery

Become a part of our network

The Von Roll Institute is the leading European center of expertise in high-voltage technology. We specialize in the development of insulation for motors, generators and transformers and operate out of three international locations.

The core of revolutionary innovation

As a research facility, we at the Von Roll Institute provide you with expertise based on over 100 years’ experience in the insulation business. As well as other developments, we designed two revolutionary innovations: the flexible insulation material mica splitting and mica paper.

You can benefit from our experience by involving our team in the development of your insulation systems – including consultants, advisors, and researchers. As a result, you save time on development, reduce long-term costs of production, and increase the lifespan of your rotating machinery.

We look forward to collaborating with you.

As an innovation partner, we support leading manufacturers of rotating machinery with solutions for high-voltage insulation systems.

We have developed and tested made-to-measure insulation systems for over 100 years.

In this way, we help reduce your production costs, increase the lifespan and efficiency of your machinery, and improve user safety.

As a global center of expertise, we are the central contact point for questions relating to electrical insulation systems in rotating machinery.

With our expertise, we advance technical designs and innovations for a new generation of electrical drives.

Meet the experts

With us, you can always find the right contact for any insulation component. We have experts in wiring, main insulation, resins, adhesives and composite materials. In an extensive consultation session, we will assess your requirements and put together the right team of consultants for you. Our experience and expertise in this field is virtually unparalleled.
