Overview

EN 60317-80/prA1:2026, issued by CLC, is an amendment to the standard defining technical specifications for polyvinyl acetal enamelled rectangular copper wire, class 120, with a bonding layer. This amendment falls under the broader umbrella of standards on winding wires, which are crucial in electrical engineering sectors for manufacturing electrical coils, transformers, and motors. The amendment reflects the latest consensus in the industry and aims to ensure enhanced quality, performance, and safety of winding wires with polyvinyl acetal insulation.

Key Topics

• Polyvinyl Acetal Enamelled Wire: This standard targets copper wires coated with polyvinyl acetal - a family of thermoplastic vinyl resins created via condensation of polyvinyl alcohols with aldehydes (e.g., polyvinyl formal, polyvinyl butyral).
• Class 120 Thermal Endurance: The classification indicates the wire's ability to maintain performance at a specified temperature (120°C) over time, vital for reliability in demanding electrical applications.
• Rectangular Copper Wire: Specifies the shape (rectangular cross-section) of the conductor, which is commonly used for improved packing density and thermal management in windings.
• Bonding Layer: Highlights the additional bonding layer on the insulation, which aids coil manufacturing processes by allowing wires to be fused or bonded in-situ, thus enhancing mechanical stability.
• Testing Procedures: Amendment updates certain clauses, such as the appropriateness of the cut-through test, aligning with technological advances and current best practices.

Applications

EN 60317-80/prA1:2026 applies to sectors and products where high-quality, thermally resilient, and mechanically robust winding wires are critical, including:

• Electric Motors: Used in the stator and rotor windings due to the combination of thermal endurance and precise wire geometry.
• Transformers: Enables compact, high-efficiency coil designs where insulation integrity and bonding are essential.
• Generators: Ensures reliability and durability in continuous-operation environments.
• Relays and Contactors: Suitable for components requiring stable coil formation and enhanced layer adhesion.
• Automotive and Industrial Electrification: Essential in devices operating at elevated temperatures and under mechanical stress.

The inclusion of a bonding layer enhances the wire's utility in automated coil-winding processes, supporting higher production efficiency and consistent quality.

Related Standards

The following standards are closely related to EN 60317-80/prA1:2026 and provide additional guidance for winding wires and copper conductor products:

• EN 60317-80: The base document for specifications on polyvinyl acetal enamelled rectangular copper wire.
• IEC 60317 Series: International standards covering specifications for a wide range of winding wires, including different insulation materials and shapes.
• EN 60317-0-1: General requirements for winding wires, applicable to all types within the EN 60317 series.
• EN 60216: Methods for evaluating the thermal endurance properties of electrical insulating materials.
• EN 13601: Technical requirements for copper and copper alloy rods, wires, and sections used for electrical purposes.

By following EN 60317-80/prA1:2026 and related standards, manufacturers and users can ensure compliance, product reliability, and safe operation across a broad spectrum of electrical equipment and systems. This amendment represents a commitment to harmonization and continual improvement in electrical insulation technology.
