Ruby Mica Co. Ltd


Glass Mica Polyester Tape




We are instrumental in manufacturing, exporting and supplying Glass Mica Polyester Tape. Our Glass Mica Polyester Tape is known for its unique blend of high tensile strength imparted by glass cloth, strong electrical resistance and superior thermal endurance. Glass Mica Polyester Tape can withstand the rigorous overhang taping operation through sharp bends and curves without losing their insulation value. We provide Glass Mica Polyester Tape in two different insulation classes. Further, Glass Mica Polyester Tape finds wide application in overhung insulation of the coils and bars in HT motors and generators.

 

Ruby Mica Glass / Mica / pet Film Tape is a lamination of uncalcined muscovite mica paper with pet film one side and glass cloth on the other, making it a three layer high-performing mica tape. What makes this tape truly special is its unique blend of high tensile-strength imparted by glass cloth, strong electrical-resistance borrowed from the Pet film, and superior thermal-endurance brought about by the use of best-quality mica there is.

 

These tapes can withstand the rigorous overhang taping operation through sharp bends and curves without loosing their insulation value. They can be supplied in two different insulation classes. Class H insulation uses only the high thermal-grade silicone resin or modified polyester resin as a binder, whereas class f insulation uses an epoxy resin as a binder.

Less space constraints give way to a thicker insulation for the coil overhangs. An Additional fourth layer of pet film may also be laminated on the glass cloth side. This PGMP Tape has an increased dielectric value, better tensile-strength and provides a seamless mica tape-lapping on the coils.

 

Application :

Overhang Insulation of the coils / bars in HT motors and generators due to its high thermal, dielectric and mechanical values.

 

PGMP wrappers are used for ground-insulation in HT motors and generators as well.

 

Superior flexibility and high mechanical-strenght, renders our GMP / PGMP tapes hand as well as machine-taping compatible.

 

Availability :

  • Tape roll / Folium / Wrapper :
  • Length : 25 – 200m
  • Width : 15 – 1000 mm

 

Packing : Tapes are packed in airtight robust boxes Protecting them from dirt, dust and moisture. The packaging also ensures safe transit and storage.

 

Storage: 12 months at < 20oC
