MICA PGMP / GMP TAPE – AVAILABLE WITH US
PGMP / GMP Tapes consist of high grade re constituted mica paper with E low alkali fibreglass fabric as a carrier material and laminated with electrical grade polyester film on both or one side to make it a very flexible insulator.
These Tapes are characterized by high flexibility, high dielectric strength and a uniform thickness. Due to low compression on application of pressure, these tapes leave no void or empty spaces between and among insulating layers.
Application
PGMP / GMP Tapes are suitable for overhang insulation of HT coils of class F machines. They are also suitable as inter-turn and ground insulation for field, armature and turbo generator coils and form the most important part of insulation system of rotating machines. PGMP / GMP Tapes are compatible with most commercially available insulating varnishes / resins.
