IEC 60317-72:2020 specifies requirements of polyester glass-fibre wound fused, silicone resin or varnish impregnated bare, grade 1 or grade 2 enamelled round copper winding wire, temperature index 200. The impregnating agent is a silicone containing resin or varnish. 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.
