DANSK DSF/EN 60317-47/PRA1 [ Draft ]

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
