Specifications for particular types of winding wires - Part 38: Polyester or polyesterimide overcoated with polyamide-imide, enamelled round copper wire, class 200, with a bonding layer

IEC 60317-38:2013 specifies the requirements of enamelled round copper winding wire of class 200 with a triple coating. The underlying coating is based on polyester or polyesterimide resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The secondary coating is based on polyamide-imide resin. The third 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 diameters covered by this part is: - Grade 1B: 0,050 mm up to and including 1,600 mm; - Grade 2B: 0,050 mm up to and including 1,600 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. This second edition cancels and replaces the first edition published in 1992, Amendment 1:1997 and Amendment 2:1999. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - new 3.2.2 containing general notes on winding wire, formerly a part of the scope; - revision to references to IEC 60317-0-1:2013 to clarify that their application is normative; - new Clause 23, Pin hole test. Key words: requirements of enamelled round copper winding wire, class 200, triple coating

Overview

EN 60317-38:2014 (IEC 60317-38:2013) specifies requirements for enamelled round copper winding wire, class 200, with a triple coating: an underlying polyester or polyesterimide enamel, a polyamide‑imide secondary coating, and a final bonding layer based on a thermoplastic or thermosetting resin. The standard covers manufacturing, dimensional ranges and performance tests for nominal conductor diameters (Grade 1B and 2B: 0.050 mm to 1.600 mm) and replaces earlier editions. Notable updates include clarified normative references and a new pin hole test (Clause 23).

Key topics and technical requirements

• Coating system: Triple layer - polyester or polyesterimide (base), polyamide‑imide (overcoat), plus a bonding/top layer. Modified resins are permitted if the chemical identity is retained and all wire requirements are met.
• Thermal class: Class 200 - requires a temperature index ≥ 200 and heat shock ≥ 220 °C (see clause 3.2.2).
• Dimensional & electrical specs: Nominal conductor diameters per IEC 60317‑0‑1; electrical resistance and conductor tolerances follow the general requirements.
• Mechanical & electrical tests: Includes elongation, springiness, flexibility/adherence (peel tests), heat shock, cut‑through, resistance to abrasion, solvents and refrigerants, breakdown voltage, continuity of insulation, temperature index, solderability, heat/solvent bonding, dielectric dissipation, resistance to transformer oil and loss of mass.
• New/updated tests: Addition of the pin hole test to detect coating discontinuities that can compromise insulation integrity.
• Normative application: References to IEC 60317‑0‑1:2013 and other IEC test method series (e.g., IEC 60851) are normative for application of requirements and test methods.

Applications

EN 60317‑38 is intended for manufacturers and users of insulated winding wire for electrical windings where high thermal performance and robust coating adhesion are required. Typical applications include:

• Electric motors and generators
• Transformers and inductors for power electronics
• High‑temperature coils and actuators
• Automotive and industrial equipment subject to elevated operating temperatures and chemical exposure

Who uses this standard

• Winding wire manufacturers and formulators (quality and R&D)
• Motor, transformer and coil designers specifying wire insulation systems
• Test laboratories and quality assurance teams performing compliance testing
• Procurement and certification bodies verifying material conformity

Related standards

• IEC/EN 60317‑0‑1:2013 - General requirements for enamelled round copper wire (normative)
• IEC 60851 series - Test methods for winding wires
• IEC 60264 series - Packaging of winding wires

EN 60317‑38:2014 provides the technical baseline for selecting and qualifying polyester/polyesterimide + polyamide‑imide triple‑coated, class 200 enamelled copper wire for reliable, high‑temperature winding applications.
