FIELD: electrical engineering. SUBSTANCE: invention is intended for manufacture of flexible glass-mica impregnated tape applied to elements of windings at 20-30 C. Impregnating compound consists of epoxy resin, phenolformaldehyde resin, accelerator, organic solvent and polyorganosiloxane fluid. Aliphatic tertiary amine aromatic nuclei with following relation of components in parts by mass per 100 mass units of epoxy resin: phenolformaldehyde resin 22-47; polyorganosiloxane fluid 1-5; tertiary amine 0.030-0.150; organic solvent 90-125 is used as accelerator. EFFECT: simplified process of application of tape and design of insulating machine, reduced toxicity of insulation process. 1 dwg, 1 tbl
