Overview

SIST EN IEC 60317-93:2024 is an international standard published by the European Committee for Electrotechnical Standardization (CLC). It specifies the requirements for polyester or polyesterimide enamelled rectangular copper winding wire with an additional overcoat of polyamide-imide enamel, classified as class 220. This dual-coated winding wire is designed to meet stringent electrical, mechanical, and thermal performance criteria, suitable for high-performance electrical applications. The standard covers winding wires with nominal conductor dimensions ranging from 2.0 mm to 25.0 mm in width and 0.80 mm to 10.0 mm in thickness.

This standard complements IEC 60317-0-2:2020, which sets general requirements for enamelled rectangular copper wire and defines specific dimensional and performance parameters.

Key Topics

• Dual Coating System: The wire uses a two-layer insulation system:

  • An underlying coat of polyester or polyesterimide resin, which may be chemically modified but retains its fundamental chemical identity.
  • A top coat of polyamide-imide enamel providing enhanced thermal resistance.

• Thermal Class 220: This classification implies the wire can withstand a minimum temperature index of 220°C and heat shock resistance up to at least 240°C, making it ideal for high-temperature environments.

• Dimension Range and Grades:

  • Width: 2.0–25.0 mm
  • Thickness: 0.80–10.0 mm
  • Includes grade 1 and grade 2 wires, applicable over the entire dimension range.

• Testing and Compliance:

  • Electrical resistance, elongation, flexibility, adhesion, heat shock, abrasion resistance, solvent resistance, breakdown voltage, and solderability are among the specified test requirements.
  • Compliance with these performance tests ensures the wire meets the rigorous safety and durability standards expected for electrical equipment windings.

• Related Normative Reference: IEC 60317-0-2:2020 is referenced to maintain alignment on general wire requirements, dimensions, and test methods.

Applications

SIST EN IEC 60317-93:2024 winding wire is primarily used in the manufacture of electrical winding components requiring exceptional insulation, mechanical strength, and thermal endurance, including:

• Electric motors and generators operating at elevated temperatures.
• Transformers and inductors where rectangular copper wire geometry optimizes space and performance.
• High-performance electromagnetic coils in industrial and automotive equipment.
• Winding applications demanding wires resistant to chemical solvents, abrasion, and hydrolysis.
• Situations requiring enhanced environmental protection through dual insulation layers for prolonged operational life.

Its specification suits industries that require compliance with international electrical safety and reliability standards, including manufacturing, engineering, electronics, and energy sectors.

Related Standards

• IEC 60317-0-2:2020 - General requirements for enamelled rectangular copper wires including dimensions, testing methods, and wire characteristics.
• IEC 60851 series - Test methods for winding wires, providing comprehensive testing procedures to verify wire performance according to IEC 60317-93.
• IEC 60264 series - Packaging of winding wires standard, covering how wires are prepared and shipped to maintain quality.

Together, these standards provide a complete framework ensuring high-quality insulated winding wires that meet international electrotechnical requirements.
