    摘要: To improve its fire resistance, the winding of a low voltage coil for a dry transformer is, at its circumferential surface, covered by a wrap made up of four turns of a protective foil comprising a layer consisting of woven glass fibers impregnated with silicone resin with an admixture of mica. An inner part winding and an outer part winding are separated by a gap comprising twelve rectangular aluminium tubes as spacers. At a lower end, the end face of the winding is covered with a protective cover comprising epoxy resin.
