Anotation

This part of IEC 60317 specifies the requirements of enamelled rectangular copper winding wire of class 220 with a dual coating. The underlying coating is based on polyester or polyesterimide resin, which be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is based on polyamide-imide resin.
NOTE - A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics.
The range of nominal conductor dimensions covered by this standard is:
- width: min. 2,0 mm max. 25,0 mm;
- thickness: min. 0,80 mm max. 10,0 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
