Specifications for particular types of winding wires - Part 25: Polyester or polyesterimide overcoated with polyamide-imide enamelled round aluminium wire, class 200

IEC 60317-25:2020 is available as IEC 60317-25:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60317-25:2020 specifies the requirements of enamelled round aluminium winding wires of class 200 with a dual coating. The underlying coating is based on polyester or polyesterimide resin, which can be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is based on polyamide-imide 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 document is: - Grade 1: 0,250 mm up to and including 3,150 mm; - Grade 2: 0,250 mm up to and including 5,000 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-3:2008 and IEC 60317-0-3:2008/AMD1:2013. This fourth edition cancels and replaces the third edition published in 2010. 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 Clause 11 to take into account intermediate nominal conductor diameters; - revision to Clause 7 to indicate that the springiness test is inappropriate. - revision to Clause 16 to specify only the percentage of extractable matter and the minimum retained dielectric breakdown voltage.

Overview

EN IEC 60317-25:2020 (IEC 60317-25:2020) specifies requirements for class 200 enamelled round aluminium winding wire with a dual coating: an underlying polyester or polyesterimide enamel and a polyamide‑imide overcoat. This fourth edition (2020) replaces the 2010 edition and is published by CLC/CENELEC as the European adoption of the IEC standard. The document is available as an RLV (Redline version) showing technical changes from the previous edition.

Key facts:

• Applies to enamelled round aluminium winding wire, class 200 (temperature class).
• Dual coating: polyester or polyesterimide base coat; polyamide‑imide overcoat.
• Modified resins are permitted provided chemical identity is retained and all wire requirements are met.
• Nominal conductor diameter ranges:
  • Grade 1: 0.250 mm to 3.150 mm
  • Grade 2: 0.250 mm to 5.000 mm

Key Topics

The standard defines technical requirements, test methods and performance criteria relevant to manufacturing, testing and acceptance of enamelled aluminium winding wire. Major topics included are:

• Appearance and dimensions (reference to IEC 60317-0-3 nominal diameters)
• Electrical resistance and continuity of insulation
• Mechanical properties: elongation, flexibility, cut‑through resistance
• Thermal and dielectric performance: heat shock, breakdown voltage, temperature index
• Chemical and environmental resistance: solvents, transformer oil, refrigerants, extractable matter
• Surface and coating integrity: resistance to abrasion, pin‑hole test, adherence
• Processing characteristics: solderability, heat/solvent bonding
• Dielectric dissipation factor and loss‑of‑mass limits
• Packaging and marking requirements

Notable technical revisions in the 2020 edition:

• Addition of general notes on winding wire (clause 3.2.2).
• Clause 11 updated to include intermediate nominal conductor diameters.
• Clause 7 revised to state that the springiness test is inappropriate.
• Clause 16 revised to specify only percentage of extractable matter and minimum retained dielectric breakdown voltage.

Applications

Who uses this standard and where:

• Manufacturers of enamelled aluminium wire for motors, transformers, inductors and coils.
• Design and electrical engineers specifying winding materials for rotating machines, power transformers, consumer appliances, automotive electrics and power electronics.
• Testing laboratories and QA teams performing conformity testing and material qualification.
• Procurement and compliance specialists ensuring supplied wire meets Class 200 insulation and performance criteria.

Practical benefits:

• Ensures consistent insulation quality for reliable winding performance.
• Guides material selection for thermal, chemical and mechanical durability.
• Facilitates global trade by harmonizing product and test requirements.
