Specifications for particular types of winding wires - Part 37: Polyesterimide enamelled round copper wire, class 180, with a bonding layer

IEC 60317-37:2013 specifies the requirements of enamelled round copper winding wire of class 180 with a dual coating. The underlying coating is based on polyesterimide resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is a bonding layer based on a thermoplastic 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: 0,020 mm up to and including 1,600 mm;  - Grade 2B: 0,020 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 180, dual coating

Ta del standarda IEC 60317 določa zahteve za emajlirane okrogle bakrene navijalne žice razreda 180 z dvojno prevleko. Spodnja prevleka je osnovana na poliesterimidni smoli, ki se lahko spremeni, če ohrani kemijsko identiteto izvirne smole in izpolnjuje vse določene zahteve za žice. Vrhnja prevleka je vezana plast, ki je osnovana na termoplastični smoli. OPOMBA: Spremenjena smola je smola, ki je bila kemijsko spremenjena ali vsebuje enega ali več aditivov za izboljšanje določene lastnosti učinkovitosti ali uporabe. Razpon nazivnega premera prevodnika, ki ga zajema ta del standarda, je:
– razred 1B: od 0,020 mm do vključno 1600 mm;
– razred 2B: od 0,020 mm do vključno 1600 mm.
Nazivni premeri prevodnika so navedeni v točki 4 standarda IEC 60317-0-1:2013.

Overview

EN 60317-37:2014 (IEC 60317-37:2013) specifies requirements for polyesterimide enamelled round copper winding wire, class 180, with a bonding layer. The standard covers a dual-coating construction: an underlying polyesterimide-based enamel (which may be chemically modified while retaining its identity) and a superimposed thermoplastic bonding layer. It applies to nominal conductor diameters for Grade 1B and Grade 2B from 0.020 mm up to and including 1.600 mm and updates earlier editions with technical revisions (notably a new pin hole test and clarifications on normative references).

Key topics and technical requirements

The standard defines acceptance criteria, test methods and performance characteristics relevant to enamelled round copper winding wire (keywords: enamelled round copper winding wire, class 180, polyesterimide, bonding layer, dual coating):

• Coating system: polyesterimide enamel base + thermoplastic bonding layer; modified resins allowed if requirements are met.
• Thermal classification: Class 180 - minimum temperature index of 180 (see clause 3.2.2 for thermal notes).
• Dimensional & electrical properties: conductor diameters, electrical resistance.
• Mechanical properties: elongation, springiness, flexibility, adherence, cut‑through resistance.
• Thermal/mechanical tests: heat shock, solderability, heat or solvent bonding strength (helical and twisted coils).
• Durability & ageing: resistance to abrasion, solvents, refrigerants, transformer oil; loss of mass.
• Electrical integrity: breakdown voltage, continuity of insulation, dielectric dissipation factor.
• New additions: Clause 23 introduces a pin hole test; references to IEC 60317‑0‑1:2013 are explicitly normative.
• Packaging: wire packaging requirements are addressed in the standard.

Where applicable, test methods are aligned with IEC test standards (e.g., IEC 60851 series for winding-wire test methods).

Practical applications

This standard is aimed at manufacturers, designers and quality engineers specifying or using high‑performance insulated winding wires for electrical and electromechanical equipment. Typical applications include:

• Motors and generators (stator/rotor windings)
• Power and distribution transformers
• Inductors, chokes and solenoids
• High-temperature or high-reliability coil windings where class 180 thermal performance and bonded coatings are required

Using enamelled round copper wire conforming to EN 60317-37:2014 helps ensure reproducible insulation performance, reliable bonding for automated winding and impregnation, and consistent electrical/mechanical properties under service conditions.

Who should use this standard

• Wire and enamel manufacturers (product specification and quality control)
• OEMs of motors, transformers and coils (material procurement and qualification)
• Test laboratories and certification bodies (type testing and compliance verification)
• Design engineers specifying winding materials for high-temperature applications

Related standards

• IEC/EN 60317 series - Specifications for particular types of winding wires
• IEC 60317-0-1:2013 - General requirements for enamelled round copper wire (normative reference)
