This part of IEC 6031 7 specifies the requirements of enamelled rectangular copper winding wire of class 1 80 with a sole coating based on polyesterimide resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements.
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. 1 6,0 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 6031 7-0-2:201 3.
