Overview

EN IEC 60317-27-4:2020/prA2:2026 is Amendment 2 to the standard specifying requirements for winding wires, focusing on paper tape covered rectangular aluminium wire. Published by CLC, this amendment supports international harmonization in the production and quality assurance of aluminium winding wires used in electrical and electronic equipment. By updating specifications and test procedures, this standard ensures improved performance, uniformity, and safety in various industrial applications.

Key Topics

• Product Identification and Labelling:
  The amendment outlines requirements for clear and consistent labelling of each packaging unit. Essential information includes:

  • Manufacturer's name and/or trademark
  • Wire and paper type (e.g., trade name, IEC specification number)
  • Net mass of wire
  • Nominal conductor diameter and number of paper layers
  • Date of manufacture

• Product Scope:
  Focuses specifically on rectangular aluminium wire covered with paper tape, a preferred choice for certain electro-technical applications.

• Testing Provisions:
  The updated document clarifies that certain tests, specifically those relating to resistance to hydrolysis and transformer oil, are deemed not applicable for this type of wire.

• Compliance and Traceability:
  By requiring detailed and standardized marking on packaging, the amendment enhances traceability, quality control, and communication between suppliers and users.

Applications

Paper tape covered rectangular aluminium wire specified in this standard amendment is critical for:

• Electrical Transformers:
  Used as winding wires due to good insulation, flexibility, and efficient use of transformer space.
• Electric Motors:
  Ensures reliability and performance where specific insulation and conductor profiles are essential.
• Power Distribution Equipment:
  Applied in transmission and distribution systems for optimized electrical characteristics and cost-effectiveness.
• Industrial Machinery:
  Provides robust windings for machinery requiring rectangular profile and enhanced insulation.

This enhanced specification addresses the growing demand for reliable, high-performance wires in modern electrical assemblies. Consistent labelling and documentation help manufacturers, suppliers, and end-users maintain compliance and implement robust inventory management and quality assurance measures.

Related Standards

Organizations seeking to maintain best practices for winding wires and aluminium products should also consider the following standards:

• EN IEC 60317 Series:
  Covers a variety of specifications for winding wires, suitable for different conductor materials, insulation types, and geometries.
• IEC TC 55 Standards:
  Developed by IEC Technical Committee 55, these documents provide a broader framework for winding wire quality, safety, and testing.
• ISO/IEC Directives:
  Reference frameworks ensuring that this and related standards support cohesive international implementation.
• Related Aluminium Conductor Standards (ICS 77.150.10):
  Offer requirements for different types of aluminium products used in electrical engineering.

EN IEC 60317-27-4:2020/prA2:2026 ensures that manufacturers and users have a clear, harmonized approach to production, supply, and use of paper tape covered rectangular aluminium winding wires, supporting efficient operations and international market access.

9 FOREWORD
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
18 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
