Von Roll provides a unique, state-of-the-art range of insulation materials, composites, consulting, tests and services. Thanks to many years of experience, Von Roll is in a position to guarantee reliable, first-rate system consulting, testing, and training in the field of both resin-rich (RR) and vacuum pressure impregnation (VPI) technologies for turbo generators. We offer and deliver products to manufacturers (OEM) as well as to repair shops. Our worldwide sales and distribution network allows us to serve and consult customers, independantly of their locations.
Von Roll developed high-value products for higher performance and reliability of turbo generators. In particular we offer:
- new generation of conductive tapes that are more stable against corona effects with time and considerably increase the life span of electrical machines
- high thermal conductivity main wall tapes (Samicapor® HTC tapes) that enable higher performance through better thermal conductivity of the insulation
- fast-curring materials that substantially increase productivity
Our products are all tested as individual components as well as complete systems in our high-voltage laboratories.

Composite materials in stators are a bit different from those in rotors due to the difference in mechanical and electrical requirements.
For the insulation of high-voltage coils, we offer a complete range of high-quality products:
