Specifications for particular types of winding wires - Part 70-1: Polyester glass-fibre wound unvarnished and fused, bare or enamelled round copper wire, temperature index 155

IEC 60317-70-1:2020 specifies the requirements of polyester glass-fibre wound unvarnished and fused bare, grade 1 or grade 2 enamelled round copper winding wires, temperature index 155. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-10:2017. NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot be established. Consequently, a class based on the requirements for temperature index and heat shock temperature cannot be specified.

Les diamètres nominaux des conducteurs sont spécifiés à l'Article 4 de l'IEC 60317-0-10:2017. NOTE Pour ce type de fil, l'essai de choc thermique ne s'applique pas et la température de choc thermique ne peut donc pas être définie. Par conséquent, une classe fondée sur les exigences d'indice de température et de température de choc thermique ne peut pas être spécifiée.

Overview

EN IEC 60317-70-1:2020 (CLC/CENELEC adoption of IEC 60317-70-1:2020) specifies requirements for polyester glass‑fibre wound, unvarnished and fused round copper winding wire, supplied as bare or enamelled (grade 1 or grade 2) with a temperature index of 155. The standard covers material composition, test requirements and general conditions for these particular winding wires used in electrical equipment. Nominal conductor diameters are referenced to IEC 60317-0-10:2017. Important: the heat shock test is considered inappropriate for this wire type, so no heat shock temperature or combined class based on heat shock/temperature index is specified.

Key Topics and Technical Requirements

• Material and construction
  • Polyester + glass fibre covering (glass = electrical‑grade continuous filament; polyester = high‑grade PET from ethylene glycol and terephthalic acid).
  • Maximum polyester content in the yarn: 50% by weight.
• Wire types covered
  • Bare round copper conductor, or enamelled round copper (grade 1 or grade 2).
  • Fibre covering wound, fused and left unvarnished.
• Referenced dimensions and tolerances
  • Nominal diameters per Clause 4 of IEC 60317‑0‑10:2017.
• Test and performance topics included (standardizes test methods, acceptance criteria or references):
  • Dimensions, electrical resistance, elongation, springiness
  • Flexibility and adherence, cut‑through, resistance to abrasion
  • Resistance to solvents, breakdown voltage, continuity of insulation
  • Temperature index (155), resistance to refrigerants, solderability
  • Heat/solvent bonding, dielectric dissipation factor
  • Resistance to hydrolysis and transformer oil, loss of mass, pin hole test
  • Packaging requirements
• Notable exception
  • Heat shock test is inappropriate for this wire construction; no heat shock temperature is established.

Applications and Practical Use

• Used for windings in electrical machines and devices where a temperature index of 155 is required, for example:
  • Motors, transformers, coils, actuators, and other electromagnetic windings.
• Typical users and stakeholders:
  • Winding wire manufacturers (specification & quality control)
  • Motor and transformer designers and OEMs (material selection)
  • Procurement and QA teams (compliance checks)
  • Test laboratories and certification bodies (conformance testing)
• Practical procurement tip: specify EN IEC 60317-70-1:2020 plus required enamel grade and conductor diameter (referencing IEC 60317‑0‑10) to ensure compatibility and traceability.

Related Standards

• IEC 60317 (series) – Specifications for particular types of winding wires
• IEC 60317‑0‑10:2017 – General requirements and nominal diameters for polyester glass‑fibre wound wires
• IEC 60851 (series) – Test methods for winding wires
• IEC 60264 (series) – Packaging of winding wires

Using EN IEC 60317‑70‑1:2020 ensures consistent material composition, test coverage and interchangeability for polyester glass‑fibre wound copper wires in electrical winding applications.
