Overview

IEC 60317-62:2020 defines requirements for a specific class of winding wire: polyester glass‑fibre wound, silicone resin or varnish impregnated, bare or enamelled rectangular copper wire with a temperature index of 200. The standard covers conductor geometry, fibre covering construction, impregnating agents and which routine or special tests apply (or are inappropriate) for this wire type. It replaces the 2012 edition and refines the title, scope and glass‑fibre covering requirements.

Key scope points:

Conductor dimensions: width 2.0 mm to 16.0 mm; thickness 0.80 mm to 5.60 mm (width/thickness ratios per IEC 60317‑0‑8).
Covering: combination of polyester and electrical‑grade continuous‑filament glass fibres (polyester content ≤ 50% by weight).
Impregnation: silicone‑containing resin or varnish with a minimum temperature index of 200.
Defined covering grades: PG1 (one fibre layer) and PG2 (two fibre layers); combined with enamel grades Grade 1 or Grade 2 where applicable.

Key Topics

Materials and construction: polyester glass‑fibre yarn specification, glass‑fibre type, and maximum polyester content.
Temperature index: enamel and impregnating agent must provide a temperature index ≥ 200; temperature index depends on the impregnating agent.
Dimensional limits: nominal widths and thicknesses and reference to IEC 60317‑0‑8 for permitted combinations and ratios.
Testing applicability: many standard winding‑wire tests (heat shock, cut‑through, abrasion, solvent resistance, solderability, dielectric dissipation factor, etc.) are declared inappropriate for this wire type; where tests apply, IEC 60317‑0‑8 test clauses are referenced.
Grades & marking: distinctions between bare and enamelled conductors combined with PG1/PG2 coverings and Grade 1/Grade 2 enamel levels.

Applications

IEC 60317‑62:2020 targets manufacturers, designers and procurement specialists working with winding materials used in:

Transformers, inductors and chokes
Electric motors and generators
Power supplies and magnetics for industrial equipment
Custom coil winding and insulation systems

Who uses the standard:

Winding wire manufacturers for product specification and quality control
Motor/transformer OEMs and coil winders specifying wire for insulated windings
Test laboratories and conformity assessors referencing applicable tests and exclusions
Purchasing and compliance teams ensuring material meets temperature index and dimensional requirements
