IEC 60317-47:2013 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. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- deletion of the "in some countries" statement in the scope;
- new subclause containing general notes on winding wire, formerly a part of the scope;
- new subclause containing requirements for appearance;
- revision to the notes in Clause 19, Dielectric dissipation factor;
- new Clause 23, Pin hole test. Keywords: requirements of enamelled rectangular copper winding wire, class 240, sole coating of aromatic polyimide resin
