This part of IEC 6031 7 specifies the requirements of enamelled round copper winding wires of class 200 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 diameters covered by this document is as follows:
– Grade 1 : 0,01 8 mm up to and including 3,1 50 mm;
– Grade 2: 0,020 mm up to and including 5,000 mm;
– Grade 3: 0,0250 mm up to and including 1 ,600 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 6031 7-0-1 :201 3.
