Von Roll helps manufacturers to reduce costs and to meet the continuing demand for increased efficiency and power-to-weight ratio of AC and DC traction motors, transformers, inverters, rectifiers, circuit breakers, batteries and other applications needed in a train.
The technical requirements of electrical motors and components of a locomotive are quite demanding. The stress factors with regard to electrical, thermal and mechanical characteristics are higher than with any other system, and expectations of reliability are particularly high. This has a direct impact on insulation specifications and processes.
As the original material manufacturer, we have materials and components to meet almost all of your specificrequirements. A special focus is our electrical insulation system, developed for both resin-rich (RR) and vacuum pressure impregnation (VPI) technologies.
Von Roll delivers products for AC stators and rotors, such as conductor insulation, main wall insulation, slot wedges and stack consolidation.
Von Roll offers a wide range of wire, mica, resins and composite products for the manufacture of DC traction motors.
Traction transformers are oil filled and run at temperatures that are too high for the traditional insulation materials found in standard oil-filled transformers.
Various grades of Polyglas are used to insulate the core. Polyester Delmat is used to support the coil and Delmat parts are used together with Delglas threaded rods and nuts to assemble and consolidate the different parts of the transformer.

Switchboards and switchgears are of major importance in terms of substation equipment. Von Roll is the leader in electrical insulation systems and provides materials of high quality to support current and voltage fluctuations in power network systems.
