IEC 60317-80:2019 pdf download.Specifications for particular types of winding wires – Part 80: PolyvinyI acetal enamelled rectangular copper wire, class 120, with a bonding layer
1 Scope
This part of IEC 60317 specifies the requirements of enamelled rectangular copper winding wire of class 120 with a dual coating. The underlying coating is based on polyvinyl acetal resin, which can be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The second coating is a bonding layer based on a thermoplastic or thermosetting 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 document is: – width: min.2,00 mm max.16,00 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 nominal width and thickness as well as the specified ratio width/thickness are given in IEC 60317-0-2:2019.

3 Terms, definitions, general notes and appearance
3.1 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60317-0-2:2019 apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: 3.2 General notes 3.2.1 Methods of test Subclause 3.2.1 of IEC 60317-0-2:2019 applies. In case of inconsistencies between IEC 60317- 0-2:2019 and this part of IEC 60317, this document IEC 6031 7-80 shall prevail. 3.2.2. Winding wire Class 120 is a thermal class that requires a minimum temperature index of 120 and a heat shock temperature of at least 155 °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.
