    摘要: A method of insulating an electromagnetic coil and the resultant product thereof which involves wrapping first and second overlapping layers of fluorinated ethylene propylene (FEP) resin-coated polyimide tape around distal sections of the end turns of the coil, inserting conforming laminae of FEP resin-impregnated glass cloth between adjacent coil turns, wrapping at least two overlapping layers of FEP resin-coated polyimide tape around the entire coil, heating the coil to at least the resin melting point, applying pressure to compress the tape and laminae and to clamp together the respective turns of the coil. and finally cooling the coil under pressure to allow the resin to resolidify. The resulting product has a thin, uniform coating of impervious electrical insulation characterized by improved heat transfer capability and improved stability at high temperatures.
