IEC 60317-0-10:2017

Overview

IEC 60317-0-10:2017 sets forth the general requirements for polyester glass-fibre wound fused, unvarnished, or resin or varnish impregnated, bare or enamelled round copper winding wires. Published by the International Electrotechnical Commission (IEC), this standard forms part of the comprehensive IEC 60317 series, which provides specifications for winding wires commonly used for electrical windings in transformers, motors, and similar equipment.

This document ensures that insulated wires for windings meet consistent international requirements, supporting quality, reliability, and interoperability across various electrical and electronic applications. Key coverage includes definitions, dimensions, appearance, electrical properties, mechanical performance, and guidelines for packaging.

Key Topics

• Wire Construction: Covers round copper wires that are either bare or enamelled, with a covering of polyester and glass-fibre, which may be fused, unvarnished, or resin or varnish impregnated.
• Grades and Covering Types:
  • Bare or enamelled copper in grade 1 or grade 2
  • Single or double glass fibre covering (PG1 or PG2)
  • Combinations such as enamelled grade 1 or grade 2 wire with either single or double polyester glass fibre covering
• Dimensional Requirements: Specifies a broad range of nominal conductor diameters and outlines detailed tolerances and increases in diameter due to covering for both single and double covering types.
• Mechanical and Electrical Performance:
  • Minimum elongation levels depending on wire diameter
  • Tests for breakdown voltage according to the type of wire and covering
  • Mandrel winding and adherence tests to ensure flexibility and coverage integrity
• Appearance and Quality: Requires a smooth, damage-free fibrous covering, as verified on original packaging, aligning with commercial best practices.
• Packaging and Marking: Highlights packaging best practices, spool/container specifications, and labeling requirements-ensuring traceability and maintaining wire properties during storage and transportation.

Applications

IEC 60317-0-10:2017 applies to insulated wires used for windings in various electrical devices where mechanical resilience, thermal resistance, and insulation quality are paramount. Key application areas include:

• Power and Distribution Transformers: Ensures long-term reliability and performance where winding insulation is critical.
• Electric Motors and Generators: Applicable to both industrial and consumer products, supporting efficient electromagnetic coil function.
• Relays, Solenoids, Inductors, and Chokes: Ideal for electromagnetic components that require precise winding and insulation specifications.
• Specialty Electronics and High-Voltage Coils: Used in electrical equipment where glass-fibre-reinforced insulation offers enhanced protection and durability.
