Glass/ Micanite/ PET Film Tape

General Details
Ruby Mica® Glass / Micanite / PET Film Tape is a lamination of single-layer high-quality muscovite natural mica splitting with PET film on one side and glass cloth on the other, bonded together using an isophthalate alkyd varnish. Due to the presence of mica in its natural form, this tape has high resilience, flexibility and impact-resistant properties.

APPLICATION

Inter-turn and main insulation on end-windings of hydro-generators and motors with Class F insulation. Also used as a winding-component for bus bars, pole-to-pole jumpers, terminal bars, and various insulation purposes in turbo ­generators.
