Abstract
1,182,871. Transformers; electric coils. DOW CORNING CORP. 18 March, 1968 [11 April, 1967], No. 12881/68. Headings H1P and H1T. In the windings of an electrical inductive apparatus, e.g. a transformer, which is impregnated with an insulating medium the insulating members separating the layers of turns have a resilient, insulating coating. In the transformer in Fig. 3, the concentric layers 21, 26 and 27-29 of conductors are separated by sheets of kraft paper, e.g. 22, coated with silicone rubber or gel 23. Particles 24 of a rigid insulating material, such as grains of sand, glass beads or particles of epoxy resin, are embedded in the coating to space it from the conductors and thereby facilitate the free flow of impregnant during manufacture. The insulation 18 between the low and high voltage windings comprises two or more turns of the coated paper. Any synthetic elastomer is suitable for the coating. The impregnant may be a synthetic resin, e.g. epoxy or silicone resin.
