Research of effectiveness of convection and methods thermoradiative capsulating winding insulation for repair of electric machines tpn

The article studies comparing the effectiveness of using thermoradiation and convective drying methods insulation windings of electrical machines of traction rolling stock, impregnated with various modern varnishes and compounds at their factory and depot repair. Objective factors in the comparison methods are parameters such as temperature class, electric strength and cementing capacity. The author substantiates advantage thermoradiation method over convective.
