This part of IEC 6031 7 specifies the requirements of enamelled rectangular copper winding wire of class 240 with a sole coating of aromatic polyimide resin.
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.
Wires of grade 1 and grade 2 are included in this specification and apply to the complete range of conductors.
The specified combinations of width and thickness, as well as the specified width/thickness ratio, are given in IEC 6031 7-0-2.
