What is BS EN IEC 60317-0-8- Polyester glass-fibre wound copper wire about?
This part of IEC 60317 forms an element of a series of standards which deals with insulated wires used for windings in electrical equipment. The main objective of the series is to ensure winding wires offer optimum electric strength and service life and minimize risk of product failure.
BS EN IEC 60317-0-8 specifies the general requirements of polyester glass-fiber wound fused, unvarnished, or resin or varnish impregnated bare, or grade 1 or grade 2 or enamelled rectangular copper winding wires.
BS EN IEC 60317-0-8 covers conductor dimensions that specify:
- Widths: 2,00 mm up to and including 16,00 mm
- Thicknesses from 0,80 mm up to and including 5,60 mm
Who is BS EN IEC 60317-0-8- Polyester glass-fibre wound copper wire for?
BS EN IEC 60317-0-8 on particular types of winding wires is relevant to:
- Manufacturers of copper winding wires
- Manufacturers of electrical applications such as generators, transformers, etc
- Electrical engineers
- Mechanical engineers
Why should you use BS EN IEC 60317-0-8- Polyester glass-fibre wound copper wire?
Winding wires are largely used in the construction of applications such as transformers, motors, and generators. The main purpose of a winding wire is to interchange electrical energy with magnetic energy.
BS EN IEC 60317-0-8 includes winding wires with fibre covering of a combination of polyester and glass fibres and provides two grades of thickness for coatings. BS EN IEC 60317-0-8 provides nominal cross-sectional areas based on width and thickness that determines the resistance of the wire. As a result, you can ensure winding wires meet the needs of the specific application. BS EN IEC 60317-0-8 provides specifications on appearance, dimensions and physical properties of wending wires including elongation, durability, resistance, and pliability.
Compliance with BS EN IEC 60317-0-8 can ensure, through standardised methods, the extent of the materials’ resistance to bending, flammability at elevated temperatures, humidity resistance, and resistance to chemical and biological effects. This enables you to make the right production decisions to ensure durability and long service life of winding wires. BS EN IEC 60317-0-8-compliant polyester glass-fibre wound copper wire can thus improve dielectric strength and mechanical properties.
