Overview

EN IEC 60317-27-3:2019/prA2:2026 is an amendment to the international standard specifying requirements for particular types of winding wires, specifically paper tape covered rectangular copper wire. Published by the European Committee for Electrotechnical Standardization (CLC) and prepared by IEC Technical Committee 55 (Winding Wires), this amendment addresses updated specifications for the production and packaging of these copper winding wires used extensively in electrical manufacturing and power distribution sectors.

This amendment is relevant for manufacturers, suppliers, and users of winding wires, as well as for those involved in conformity assessment and quality assurance in electrical and electronic engineering.

Key Topics

• Product identification and labeling: The amendment introduces requirements regarding the labeling of packaging units for paper tape covered rectangular copper wire. Labels must be attached to each packaging unit and include:

  • Manufacturer's name and/or trade mark
  • Type of wire and paper, including trade name and/or relevant IEC specification number
  • Net mass of the wire
  • Nominal conductor diameter and the number of paper layers
  • Date of manufacture

• Testing requirements: The amendment replaces the clause on resistance to hydrolysis and transformer oil, specifying that this particular test is deemed inappropriate for this wire type under the updated specification.

• International alignment and consensus: The document is prepared within the ISO/IEC Directives framework, ensuring international harmonization and consensus on the technical requirements for these wires.

• Scope of application: Focus is placed on paper tape covered rectangular copper wires, which are used where precise insulation and specific geometric wire configurations are critical to performance.

Applications

The specifications and requirements defined in EN IEC 60317-27-3:2019/prA2:2026 have broad applications across industries where high-quality, reliable winding wires are essential:

• Transformer manufacturing: The winding of power and distribution transformers often uses rectangular copper wire insulated with paper tape for enhanced dielectric strength and efficient use of winding space.

• Electrical machinery and equipment: Motors, generators, and reactors benefit from paper tape covered wires where enhanced insulation and controlled conductor shape are important for performance and longevity.

• Quality assurance and procurement: Consistent and clear labeling as mandated by the standard aids in traceability, inventory management, and quality checks, ensuring users receive products that meet agreed-upon requirements.

• Conformity assessment: Manufacturers and third-party testers can reference these specifications to verify wire quality and compliance, minimizing risks during installation and operation.

Related Standards

Several standards are related to and provide context or complementary requirements for EN IEC 60317-27-3:2019/prA2:2026:

• EN IEC 60317 series: Covers various winding wire types, materials, and forms, each with specific insulation and conductor properties.
• IEC 60317-27-3: The primary standard detailing paper tape covered rectangular copper wire, to which this amendment refers.
• ISO/IEC Directives: Governs standard development processes, ensuring consistency across international and European applications.
• IEC 60104: Specifies test procedures for electrotechnical winding wires.
• Product-specific standards covering transformer and motor construction, which typically reference the EN IEC 60317 series for wire selection and specifications.

---

By adhering to EN IEC 60317-27-3:2019/prA2:2026, stakeholders can ensure uniform quality, improved traceability, and compliance with international best practices for paper tape covered rectangular copper winding wires. Implementing these standards contributes to safety, reliability, and efficiency in electrical equipment manufacturing and operation.

10 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
11 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
12 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
13 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
14 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
15 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
16 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
17 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
