Overview
IEC 60317-0-6:2020 defines the general requirements for glass-fibre wound resin or varnish impregnated, bare or enamelled, round copper winding wires. These specialized winding wires are produced for electrical and electronic applications where enhanced mechanical and thermal resistance is required. The wire types covered include those with one or two layers of glass-fibre covering, either over a bare conductor or over enamel insulated conductors.
This second edition replaces the previous edition and its amendment with technical revisions, including updated requirements for appearance, revisions to maximum overall diameters for certain wire grades, and clarification of elongation measurement.
IEC 60317-0-6 is a key standard in the winding wire and magnet wire manufacturing industry, ensuring quality, safety, and global compatibility across electrical equipment applications.
Key Topics
- Scope of Application: Covers glass-fibre wound resin or varnish impregnated, bare or enamelled, round copper wires, with conductor diameters specified in related sheets.
- Conductor and Covering Grades: Specifies types and grades for enamelled wires and glass-fibre coverings such as Grade 1 (single) or Grade 2 (double) glass-fibre layers.
- Dimensional Requirements: Provides details on nominal conductor diameters, tolerances, the increase in diameter due to glass-fibre covering, and allowed maximum overall diameters for both single and double covered wires.
- Mechanical Properties: Addresses important characteristics such as elongation (minimum defined by conductor diameter), springiness for larger diameters, and flexibility/adherence of the glass-fibre covering under stress.
- Electrical Properties: Outlines breakdown voltage requirements for both bare and enamelled wires with glass-fibre coverings, ensuring suitability for insulation and voltage withstand applications.
- Packaging and Identification: Guidance on agreed packing methods, spool/container labeling, and traceability information to maintain product quality during storage and transportation.
- Testing Methods: Relies on IEC 60851 series for standardized procedures covering dimensions, electrical resistance, breakdown voltage, elongation, and more.
Applications
Glass-fibre wound, resin or varnish impregnated copper winding wires are crucial in applications where reliable insulation and enhanced mechanical protection are required under elevated temperature and demanding conditions. Typical uses include:
- Transformers: High reliability windings where thermal endurance and dielectric strength are critical.
- Rotating Electrical Machines: Motors and generators, especially where vibration and heat are significant operational factors.
- Electrical Reactors and Coils: Used where robust mechanical protection of the winding is needed.
- Industrial Electronics: Suitable for inductive components in environments requiring mechanical toughness and longevity.
By adhering to IEC 60317-0-6:2020, manufacturers, designers, and procurement engineers ensure compatibility and safety, minimize risk, and enable easier sourcing of winding wires for global applications.
