Glass banding tapes

Polyglas® is a trade name of VON ROLL for a range of banding tapes consisting in parallel glass plied yarns pre-impregnated with a special thermosetting polyester PEI (polyesterimid) based resin.
Polyglas® tapes are suitable for a bracing tape for tying form wound coils and for locking dry or oil – filled transformer columns.
Main advantages of Polyglas® tapes are:

  • Eddy currents proof material and locally not exposed to overheating;
  • Outstanding properties of breaking through fatigueа;
  • Elimination of flashover among windings and steel bands;
  • Saving in insulating materials and in weight;
  • Saving in material costs and in process costs through reduced application time;

Resistance to corrosion in tropical environments.
