FIELD: manufacture of materials for electrotechnical products, particularly, impregnation of bundle products. SUBSTANCE: to oligoether acrylate, unsaturated polyether resin and peroxide polymerization initiator, the electroinsulating impregnating compound further comprises siccative and organic isocyanate. Electrotechnical products are impregnated with said composition, the composition is then polymerized at 120-140 C and wetted. Additional polymerization is carried out at 110-150 C. The resulting electrotechnical products are free from defects along interbundle and interphase shortings. EFFECT: improved properties of the electroinsulating impregnating compound. 3 cl, 17 ex, 4 tblv |
