Overview

SIST EN 60317-28:2014/oprA2:2026 is an amendment to the international standard that defines the specifications for polyesterimide enamelled rectangular copper wire, class 180, specifically designed for winding applications. Issued by the Slovenski inštitut za standardizacijo (SIST), this amendment aligns with the requirements set out by IEC Technical Committee 55, focusing on the electrical and electronic industries' needs for reliable winding wires.

The standard is recognized as identical to EN 60317-28:2014/prA2:2026 and falls under the International Classification for Standards (ICS) codes 29.060.10 (Wires) and 77.150.30 (Copper products). Its primary audience includes manufacturers, quality assurance professionals, and technical committees involved in electric transmission, distribution, and the safety of electrical apparatus.

Key Topics

• Polyesterimide Enamelled Rectangular Copper Wire: Properties and specifications of copper conductors with a polyesterimide (Class 180) enamel coating, intended for use in electrical windings.
• Amendment Content: Updates and clarifies requirements, including changes to resistance to hydrolysis and transformer oil, reflecting evolving operational demands.
• International Harmonization: Developed in line with ISO/IEC directives, ensuring the standard is applicable both regionally and globally.
• Committee Collaboration: Emphasizes involvement by international technical committees and parallel voting procedures with CENELEC, supporting European and global market acceptance.

Applications

Polyesterimide enamelled rectangular copper wires specified in this amendment are essential for a variety of electrical and electronic applications, especially where high thermal resistance is crucial:

• Electrical Transformers: Used as winding wire for coils due to their robust insulation and thermal class 180 rating, suited for applications demanding high reliability and longevity.
• Electric Motors and Generators: Ensures efficient performance under thermal and electrical stress, reducing failure risks.
• Other Electromechanical Devices: Relevant for any equipment requiring form-wound coils with rectangular wire profiles, such as inductors and certain advanced power electronics.
• Transmission and Distribution Equipment: Supports safe and efficient electricity distribution by maintaining insulation integrity under various environmental conditions.

Key benefits include:

• Reliable insulation performance at elevated operating temperatures (Class 180)
• Improved process stability and consistency in winding applications
• Compatibility with established manufacturing and testing protocols for winding wires

Related Standards

This amendment is part of a wider portfolio of standards for winding wires and related materials, which include:

• EN 60317 Series / IEC 60317 Series: Comprehensive specifications for a variety of winding wire types including round or rectangular, copper or aluminum, and diverse enamel coatings.
• IEC TC 55: The technical committee responsible for international standardization of winding wires, ensuring global alignment.
• ISO/IEC Directives, Part 1 and Part 2: Governing frameworks for preparing and drafting international standards, ensuring consistency and quality.
• EN 60317-28:2014: The principal standard for polyesterimide enamelled rectangular copper wire, to which this amendment applies.

For businesses and professionals in the electrical industry, compliance with SIST EN 60317-28:2014/oprA2:2026 and its related standards ensures not only operational safety and performance, but also market acceptance throughout Europe and many other regions. By following these specifications, manufacturers can meet regulatory requirements and support international trade in winding wire products.

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.
