Overview

SIST EN IEC 60317-27-4:2020/oprA2:2026 is an amendment to the international standard governing paper tape covered rectangular aluminium wire, essential for various electrical winding applications. Published and maintained by SIST in alignment with IEC and CENELEC guidelines, this amendment addresses specification requirements for particular types of winding wires, facilitating safer, more efficient, and high-performance electrical equipment manufacturing.

Winding wires like paper tape covered rectangular aluminium conductors are crucial in the construction of transformers, electrical motors, and generators. This amendment ensures uniform requirements and quality in the production, packaging, and identification of such specialty aluminium wires across multiple industries.

Key Topics

• Standardization of Paper Tape Covered Aluminium Wires
  The amendment refines requirements for rectangular aluminium wire covered with paper tape, clarifying details relevant to identification, packaging, and information exchange between the supplier and the user.

• Labeling and Packaging Requirements
  To enhance traceability and quality assurance, labels must be attached to each packaging unit with the following information:

  • Manufacturer’s name and/or trademark
  • Type of wire and type of paper, including trade name or IEC specification number
  • Net mass of wire
  • Nominal conductor diameter and number of paper layers
  • Date of manufacture

• Testing and Suitability
  The amendment also addresses the appropriateness of specific tests (e.g., resistance to hydrolysis and transformer oil), providing clarity on instances where standard tests are not applicable.

• International Harmonization
  Developed by IEC Technical Committee 55 (Winding Wires), this amendment promotes global harmonization of wire specifications, supporting cross-border electrical equipment manufacturing and procurement.

Applications

Paper tape covered rectangular aluminium wire specified in this document is widely applied in:

• Power Transformers: Serves as coil windings due to its excellent insulation and efficient thermal management properties.
• Distribution Transformers: Provides reliable and safe insulation, especially in oil-immersed designs.
• Electrical Motors and Generators: Used where strong dielectric strength and mechanical reliability are critical in windings.
• Specialized Electrical Equipment: Suitable for other custom applications where rectangular aluminium winding wire with paper insulation is required for performance or regulatory compliance.

By defining clear standards for packaging and labeling, manufacturers and suppliers can ensure their products are easily traceable, meet international requirements, and support streamlined logistics and inventory management.

Related Standards

For comprehensive compliance and quality assurance in the use of winding wires and related products, the following standards may be referenced:

• EN IEC 60317-27-4: The parent standard, detailing base specifications for paper tape covered rectangular aluminium wire.
• IEC 60317 Series: General specifications and test methods for winding wires of various materials and coverings.
• ISO/IEC Directives: Procedures and development principles for IEC and ISO standards.
• SIST Standards: Slovenian national standards harmonized with European and international requirements in electrical engineering.

SIST EN IEC 60317-27-4:2020/oprA2:2026 is instrumental in advancing consistency, quality, and safety in the manufacturing and application of paper tape covered rectangular aluminium winding wires for the global electrical industry. By following this amendment, organizations can achieve improved operational safety, regulatory compliance, and international market access for wire products.

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.
