Application Summary AI generated

This standard specifies requirements for mica paper tapes reinforced with glass fabric or film and bonded with epoxy resin, designed specifically for vacuum pressure impregnation (VPI) processes. It is applied in the electrical industry for insulating high-voltage rotating machinery, such as generators and large motors, where the tape is wrapped around coils and then impregnated with resin under vacuum and pressure to ensure void-free insulation. The standard ensures consistent thickness, tensile strength, and resin compatibility for reliable performance in demanding power generation and industrial equipment.
