It is made of undirectional layer of cabled glass impregnated Under tension with a modified thermo setting resin for class 'H' Insulation.                         Resi Glass Tape can Successfully replace steel band with the following advantages. 1. Under Layer insulation is not required. 2. Increased resistance to humidity and corrosion. 3. Electrical losses and flash over hazards are reduced. 4. Band is bonded to the winding improving stability. Resiglass Tape is supplied in 'B' tape semi-cured Resin system. The Free flow characteristic of the resin avoids air space in the band there by improves heat dissipation factor and greatly adds its stability under all operating. Dimension and Tolerance
