The superimposed coating is based on polyamide-imide resin.  NOTE A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics. The range of nominal conductor dimensions covered by this standard is:
- width: min. 2,0 mm - max. 16,0 mm;
- thickness: min. 0,80 mm - max. 5,60 mm.
Wires of grade 1 and grade 2 are included in this specification and apply to the complete range of conductors. The specified combinations of width and thickness as well as the specified width/thickness ratio are given in IEC 60317-0-9:2015.

Overview

SIST EN IEC 60317-73:2018 is a European standard developed by CLC that specifies the requirements for particular types of insulated winding wires, specifically polyester or polyesterimide overcoated with polyamide-imide enamelled rectangular aluminium wire, classified as class 200. This dual-coated wire is designed for use in electrical equipment windings, providing high electrical insulation, thermal endurance, and mechanical robustness. It addresses a range of nominal conductor dimensions, ensuring consistent product quality and performance.

The standard forms part of the IEC 60317 series, dedicated to specifications for particular winding wires, complementing test methods (IEC 60851) and packaging standards (IEC 60264). It defines essential characteristics, test methods, and dimensions aimed at manufacturers, engineers, and quality controllers in the electrical and electronics industries.

Key Topics

• Dual coating system: The wire comprises an underlying polyester or polyesterimide resin coating, which may be chemically modified to improve performance while maintaining its fundamental chemical identity, and a superimposed polyamide-imide resin enamel coating.
• Class 200 thermal rating: Ensures a minimum temperature index of 200°C and a heat shock temperature of at least 220°C, suitable for high-temperature applications.
• Dimensional specifications:
  • Width: 2.0 mm to 16.0 mm
  • Thickness: 0.80 mm to 5.60 mm
• Grades: Includes grade 1 and grade 2 wires, covering the entire dimensional range.
• Test and performance requirements: The standard references rigorous testing consistent with IEC 60317-0-9:2015, including electrical resistance, elongation, flexibility, adhesion, heat shock, solvent resistance, breakdown voltage, continuity of insulation, and temperature index.
• Exclusions: Certain tests such as cut-through and resistance to abrasion are deemed inappropriate for this wire type, reflecting its unique construction.
• Standardized terminology: Adopts definitions from IEC 60317-0-9 and ensures consistency with global terminologies maintained by IEC Electropedia and ISO online databases.

Applications

SIST EN IEC 60317-73:2018 insulated aluminium winding wires are extensively used in electrical machines and devices requiring reliable insulative properties combined with resistance to thermal and mechanical stress. Typical applications include:

• Motors and generators where space-saving rectangular conductors are beneficial for efficient winding.
• Transformers and inductors requiring high dielectric strength and thermal endurance.
• High-performance electrical equipment exposed to elevated temperatures up to 200°C.
• Electrical systems benefiting from aluminium’s lightweight and cost efficiencies enhanced by advanced enamel coatings for durability.

The standard ensures that wiring components used in such applications meet stringent quality and reliability criteria, guaranteeing safe and efficient operation.
