This part of IEC 60317 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. 16@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 60317-0-2.
