Abstract:
A method of increasing compressive creep capabilities of high voltage coil insulation, the method comprising the steps of:applying at least one layer of a first tape as a groundwall insulation to substantially the entire length of a high voltage coil, the first tape having a first predetermined amount of resin therein; curing the groundwall insulation for a first predetermined time period; applying at least one layer of a second tape, said second tape comprising a glass backed mica paper tape, as a protective armor overlying the cured groundwall insulation only to end portions of the high voltage coil after the first predetermined time period, the second tape including a second predetermined amount of resin and the second predetermined amount of resin being substantially more than the first predetermined amount of resin; and curing the protective armor for a second predetermined time period.
