This part of IEC 60317 specifies requirements of polyester glass-fibre wound, silicone resin or varnish impregnated bare, grade 1 or grade 2 enamelled rectangular copper winding wire, temperature index 200. The impregnating agent is a silicone containing resin or varnish. The range of nominal conductor dimensions covered by this standard is: width: min. 2,0 mm max. 16,0 mm; thickness: min. 0,80 mm max. 5,60 mm. The specified combinations of width and thickness as well as the specified width/thickness ratio are according to IEC 60317-0-8. 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.
