IEC 60317-89:2023

Overview

IEC 60317-89:2023 is an international standard published by the International Electrotechnical Commission (IEC) that defines the specifications for particular types of winding wires, focusing specifically on polyesterimide enamelled round aluminium wire, class 200. This standard applies to aluminium winding wires coated with polyesterimide resin or its modified variants, provided they preserve the chemical identity of the original resin and comply with the detailed performance requirements. Covering a broad range of nominal conductor diameters, IEC 60317-89 ensures consistent quality and performance criteria for aluminium wires used in various electrical winding applications.

This standard is intended to be used in conjunction with IEC 60317-0-3:2008 and its amendments, which provide general requirements for enamelled round aluminium wires. IEC 60317-89 aligns with existing test methods and definitions while specifying unique parameters for class 200 polyesterimide enamelled wires.

Key Topics

• Scope: Defines the properties and requirements for polyesterimide enamelled round aluminium winding wire of class 200, covering conductor diameters from 0.250 mm up to 5.000 mm based on the grade.
• Thermal Class: Class 200 wires meet a minimum temperature index of 200 °C and a heat shock temperature of at least 220 °C, making them suitable for high-temperature electrical applications.
• Wire Coating: Sole coating with a polyesterimide resin that may be chemically modified to enhance performance without losing its fundamental resin characteristics.
• Mechanical & Electrical Tests: Includes specifications for electrical resistance, elongation, flexibility, adherence, heat shock resistance, resistance to abrasion and solvents, breakdown voltage, solderability, and more.
• Dimensions: Nominal conductor diameters and related tolerances are in accordance with IEC 60317-0-3:2008 and its amendments.
• Test Requirements: Tests such as abrasion resistance, dielectric dissipation, pinhole tests, and resistance to transformer oil are clearly outlined to ensure wire durability and reliability.
• Packaging: Packaging specifications are included to maintain wire quality during transport and storage.

Applications

IEC 60317-89 polyesterimide enamelled round aluminium wires, class 200, are primarily engineered for use in:

• Electrical winding components: Motors, transformers, generators, inductors requiring high thermal endurance.
• High-temperature environments: Applications where wires must withstand operating temperatures up to 200 °C or exposure to heat shock conditions.
• Electrical and electronic manufacturing: An ideal choice for insulation in electrical machines due to their abrasion resistance, solvent resistance, and excellent mechanical properties.
• Energy-efficient devices: Aluminium wires provide a lightweight and cost-effective alternative to copper for winding purposes.
• Refrigeration and HVAC equipment: Thanks to their tested resistance to refrigerants and transformer oil, these wires are suitable for industrial cooling and heating devices.
