One of the worldwide best known specialities of Von Roll is the development and the production of fibre-covered and taped wires which meet the most severe requirements of the electro-technical industry. Winding wires from Von Roll covered with impregnated Glass yarn (Silix®) or yarns of Glass/Polyester blend (Daglas) are used in particular in applications where the wire insulation has to show improved mechanical properties, as for example in:
• rotor and stator windings of electric motors
• rotor and stator windings of traction motors
• transformer windings
• conductor strands or Roebel bars for large power generators
