Overview

IEC 60317-59:2015 (with Amendment 1:2024) defines requirements for polyamide‑imide enamelled round copper winding wire, class 240. This part of the IEC 60317 series covers enamelled round copper wire with a single coating of polyamide‑imide resin and is intended for insulated wires used for windings where elevated thermal performance is required. It is to be read in conjunction with IEC 60317-0-1:2013 (general requirements for enamelled round copper wire).

Key topics and technical requirements

Wire type and coating: Single coating of polyamide‑imide resin on round copper conductor.
Thermal class: Class 240 - minimum temperature index 240°C; minimum heat‑shock temperature 260°C.
Conductor diameters: Covers nominal diameters for both Grade 1 and Grade 2 from 0.180 mm up to and including 1.600 mm (nominal diameters are specified in IEC 60317-0-1:2013).
Mechanical and electrical tests: Requirements reference the general test methods in IEC 60317-0-1 and IEC 60851 series. Specifics in IEC 60317-59 include:
- Cut‑through: no failure within 2 minutes at 450°C.
- Flexibility/adherence: Peel test uses constant K = 75 mm for revolution calculations.
- Breakdown voltage: Measured with elevated temperature set to 240°C.
- Resistance to abrasion: Detailed minimum average and per‑measurement forces for Grades 1 and 2 are given in Table 1 (applies to diameters 0.250–1.600 mm; intermediate sizes use the next larger diameter values).
Tests declared inappropriate or without requirements: solderability, heat/solvent bonding, dielectric dissipation factor; some refrigerant, oil and mass‑loss tests are marked “appropriate but no requirements specified” or “inappropriate” as noted in the document.
Packaging and appearance: Packaging and appearance requirements reference IEC 60317-0-1 and IEC 60264 series.

Applications and users

Who uses IEC 60317-59:

Winding wire manufacturers specifying and certifying enamelled round copper winding wire of class 240.
Motor, transformer and generator designers selecting insulated wires for high‑temperature winding applications.
Quality assurance, test laboratories and procurement teams verifying conformance to thermal and mechanical performance criteria.
Industries requiring high thermal stability in windings: industrial drives, power electronics, aerospace, automotive and specialized electrical equipment.

Why it matters:

Ensures consistent performance at elevated temperatures, reliable insulation integrity under thermal stress, and repeatable mechanical robustness (abrasion, cut‑through, flexibility) for critical winding applications.
