Do you need a multi-user copy?




IEC 60317-80: 2019 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.
