This part of IEC 6031 7 specifies the requirements of glass fibre wound, resin or varnish impregnated, bare or enamelled rectangular copper winding wire, temperature index 1 80.
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.
The range of nominal conductor dimensions covered by this standard is:
– width: min. 2,0 mm max. 1 6,0 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 6031 7-0-4.
