Abstract
Windings made from Cu wire coated with Ni to prevent oxidn. wrapped with glass fibre insulation and an additional wrapping of thin polyethylene terephthalate film which is varporised during stoving at over 250 degrees C, without reducing the heat resistance of the insulation. When combined with other components suitable for high temps., the windings can be used for prolonged periods at up to 400 degrees C. Round wire is used and the winding and processing is similar to that used for multi- and single-phase AC motors with lower temp. ratings.
