vidrio glass


Yarn covered winding wires meet the most demanding requirements of the electrotechnical industry. Our fiber covered wires are lapped with glass or with a combination of mixed glass/polyester fibers.


  • Silix®: glass yarn covered and varnish impregnated 
  • Daglas: thermally fused yarn combination of glass and polyester fibers, available both unvarnished and varnished.
  • VTV: combination of mixed glass /polyester fibers and impregnated glass yarn.
  • VS: yarn covered with outstanding thermal and mechanical properties, based on polyamide-imide or polyimide enamel for the conductor insula-
    tion and the covering impregnation.


Our yarn covered wires are ideal for applications where the wire insulation requires
improved mechanical properties, for example in:

  • rotor and stator windings
    • electrical motors (low- and high-voltage)
    • traction motors
    • wind turbine generators
  • conductor strands or Roebel bars
    • large power generators (hydro, turbo)



  • Wires with improved mechanical strength
  • High-performance yarns and impregnation varnishes
  • Wide range of insulation builds possible: standard, very thin or reinforced
  • Own means of production for a broad range of round and flat enamelled wires
