Von Roll offers a complete range of round and rectangular enameled, yarn covered or fiber covered copper wires for a wide range of applications.

  • Duroflex® round and rectangular wires. Class 120°C. Enameled wire with exceptional mechanical coating properties for high-performance transformers - electric meters.
  • Thermex® round and rectangular wires. High temperature wires with a temperature index up to 240°C for electrical and magnetic windings, transformers, motors, small industrial and wind generators.
  • Thermibond®: Self-impregnating cables. Cured at 190°C. This allows manufacturers not to use impregnating varnishes thus reducing production time cycles.
