Overview
IEC 60317-0-8:2012 sets forth the general requirements for specific types of winding wires used in electrical and electronic applications. This International Electrotechnical Commission (IEC) standard focuses particularly on polyester glass fibre wound, resin or varnish impregnated (or not), bare or enamelled rectangular copper wire. Winding wires conforming to this standard ensure performance and reliability in electrical equipment by meeting strict specifications related to their construction, dimensions, and electrical properties.
This standard forms part of the broader IEC 60317 series, which details specifications for various winding wires. It is essential for manufacturers, designers, and testing labs involved in electrical machinery and transformer production, ensuring product quality and international consistency.
Key Topics
- Material Composition: Polyester glass fibre winding, with or without resin or varnish impregnation, applied on bare or enamelled rectangular copper wire conductors.
- Dimensional Specifications:
- Conductor sizes and tolerances to maintain precise dimensions critical for winding efficiency.
- Corner radii and dimensional changes due to insulation coatings.
- Electrical Properties:
- Resistance values ensuring optimal conductivity.
- Testing for continuity of insulation and breakdown voltage to guarantee performance under electrical stress.
- Mechanical Characteristics:
- Elongation and flexibility assessments such as the mandrel winding test.
- Adherence quality of coverings and resistance to abrasion, solvents, solderability, and heat shock.
- Testing Methods: References IEC 60851 for test methods, incorporating rigorous procedures for evaluating coating integrity, dielectric properties, and soldering compatibility.
Applications
Winding wires that comply with IEC 60317-0-8:2012 are predominantly used in:
- Electric Motors and Generators: Offering reliable insulation and conductor properties required for electromagnetic windings.
- Transformers: Ensuring effective energy transfer through quality wire insulation and dimensional precision.
