IEC 60317-17 REDLINE
Specifications for particular types of winding wires – Part 17: Polyvinyl acetal enamelled rectangular copper wire, class 105
|Publication Date:||1 June 2020|
|ICS Code (Wires):||29.060.10|
This part of IEC 60317 specifies the requirements of enamelled rectangular copper winding wires of class 105 with a sole coating based on polyvinyl acetal resin, which can be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements.
NOTE 1 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.
NOTE 2 Polyvinyl acetate is a general name for a family of thermoplastic vinyl resins produced by the condensation of polyvinyl alcohol with an aldehyde. Examples are polyvinyl acetal, polyvinyl formal and polyvinyl butyral.
The range of nominal conductor dimensions covered by this document is:
- width: min. 2,0 mm max. 31,5 mm;
- thickness: min. 0,80 mm max. 10,00 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 ratio of width/thickness are given in IEC 60317-0-2.
