IEC 60317-74:2018 specifies the requirements of enamelled rectangular aluminium winding wire of class 180 with a sole coating based on polyesterimide resin, which can 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 dimensions covered by this standard is:
- width: min. 2,0 mm - max. 16,0 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 width and thickness as well as the specified width/thickness ratio are given in IEC 60317-0-9:2015.

EN IEC 60317-74:2018 - Overview

EN IEC 60317-74:2018 specifies requirements for polyesterimide enamelled rectangular aluminium wire, class 180 used as insulated wires for windings. The standard covers rectangular aluminium conductors with a single polyesterimide-based enamel coating (modifications allowed if the resin retains its chemical identity) and defines dimensional, thermal and electrical performance expectations for use in electrical windings.

Key scope items:

• Conductor dimensions: width 2.0 mm–16.0 mm, thickness 0.80 mm–5.60 mm.
• Includes grade 1 and grade 2 wires across the full size range.
• Thermal class 180 (minimum temperature index 180 °C; minimum heat shock 200 °C).
• References general requirements and test methods in IEC 60317-0-9:2015.

Key topics and requirements

• Insulation system: Sole coating based on polyesterimide resin; modified resins permitted if chemical identity preserved.
• Thermal performance: Minimum temperature index 180 °C and heat shock ≥ 200 °C for class 180.
• Dimensions and geometry: Nominal width/thickness ranges specified; exact width/thickness combinations and ratios referenced to IEC 60317-0-9.
• Electrical and mechanical tests: Electrical resistance, elongation, flexibility, adherence and breakdown voltage are handled per IEC 60317-0-9; breakdown voltage testing includes an elevated temperature of 180 °C.
• Excluded or inapplicable tests: Certain tests are declared inappropriate for this wire type (e.g., cut-through, resistance to abrasion, continuity of insulation, refrigerants, solderability, heat/solvent bonding, loss of mass).
• Under consideration: Dielectric dissipation factor and resistance to transformer oil tests are noted as under consideration.
• Packaging: Wire packaging requirements are treated in the IEC 60264 series.

Applications and who uses it

Practical uses:

• Insulated rectangular aluminium wire specified here is intended for windings in motors, transformers, inductors, chokes and other electromagnetic devices where aluminium is chosen for weight or cost advantages and a class 180 insulation system is required. Who benefits from the standard:
• Winding wire manufacturers (specification and quality control)
• Motor, transformer and coil designers (material selection and compliance)
• Test laboratories and certification bodies (conformity assessment)
• Purchasing and procurement teams specifying performance and dimensional requirements
