IEC 60317-70-2:2020 specifies the requirements of polyester glass-fibre wound resin/varnish impregnated bare, grade 1 or grade 2 enamelled round copper winding wires, temperature index 155. The impregnating agent can be, for instance, epoxy, polyester, or polyesterimide resin based. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-10:2017. NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot be established. Consequently, a class based on the requirements for temperature index and heat shock temperature cannot be specified. IEC 60317-70-2:2020 specifie les exigences relatives aux fils de bobinage de section circulaire en cuivre nus ou emailles de grade 1 ou de grade 2, guipes de fibres de verre polyester impregnees de vernis ou de resine, dindice de temperature 155. Lagent dimpregnation peut etre, par exemple, un materiau a base de resine epoxy, polyester ou polyesterimide. Les diametres nominaux des conducteurs sont specifies a lArticle 4 de lIEC 60317-0-10:2017. NOTE Pour ce type de fil, lessai de choc thermique ne sapplique pas et la temperature de choc thermique ne peut donc pas etre definie. Par consequent, une classe fondee sur les exigences dindice de temperature et de temperature de choc thermique ne peut pas etre specifiee.
