IEC 60317-25:2020 pdf free download Specifications for particular types of winding wires – Part 25: Polyester or polyesterimide overcoated with polyamide-imide enamelled round aluminium wire, class 200 (IEC 60317-25:2020)
This part of lEC 60317 specifies the requirements of enamelled round aluminium windingwires of class 200 with a dual coating. The underlying coating is based on polyester orpolyesterimide resin,which can be modified provided it retains the chemical identity of theoriginal resin and meets all specified wire requirements.The superimposed coating is basedon polyamide-imide resin.
NOTE A modified resin is a resin that has undergone a chemical change,or contains one or more additives toenhance certain performance or application characteristics.
The range of nominal conductor diameters covered by this document is:- Grade 1: 0,250 mm up to and including 3,150 mm;
-Grade 2: 0,250 mm up to and including 5,000 mm.
The nominal conductor diameters are specified in Clause 4 of lEC 60317-0-3:2008 andlEC 60317-0-3:2008/AMD1:2013.

3.2 General notes
3.2.1 Methods of test Subclause 3.2.1 of IEC 6031 7-0-3:2008, IEC 6031 7-0-3:2008/AMD1 :201 3 and IEC 6031 7-0- 3:2008/AMD2:201 9 applies. In case of inconsistencies between IEC 6031 7-0-3 and this document, IEC 6031 7-25 shall prevail.
3.2.2 Winding wire Class 200 is a thermal
class that requires a minimum temperature index of 200 and a heat shock temperature of at least 220 °C. The temperature in degrees Celsius corresponding to the temperature index is not necessarily that at which it is recommended that the wire be operated and this will depend on many factors, including the type of equipment involved.
