Specifications for particular types of winding wires - Part 47: Aromatic polyimide enamelled rectangular copper wire, class 240

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
