Poly Glass Tape is made of an unidirectional layer of cabled glass yarn impregnated under tension with a modified thermo setting resin for class 'H' insulation. Poly Glass Tape is supplied in 'B' tape semi-cured resin system. The free flow characteristics of the resin avoids air space in the band there by improves heat dissipation factor and greatly adds its stability under all operating conditions. Poly Glass Tape is designed for use as banding restrain on traction armatures, large generators and other rotating electrical machines. Poly Glass Tape can also be used for the banding of transformer cores and transformer tie-loops.

Poly Glass Tape can successful replace steel band with the following advantages:
  • Under layer insulation is not required.
  • Increased resistance to humidity and corrosion.
  • Electrical losses and flash over hazards are reduced
  • Band is bonded to the winding improving stability.
