Glass or Mica Tape
An additional layer of glass cloth may also be laminated on top of mica paper. This GMG Tape has an increased thermal conductivity for better coil-heat dissipation and nearly doubles the tensile-strength of GM tape.
Application
Inter-turn conductor insulation suitable for resin-poorVPI insulation system of HT motors and generators, Class H insulation in transformers, induction furnace coil insulation etc.
Availability
Packing
Tapes are packed in airtight robust boxes protecting them from dirt, dust and moisture. The packaging also ensures safe transit and storage.
Storage
6 months at 20C - 12 months at 5C
