Overview
IEC 60317-60-1:2020 provides specific requirements for polyester glass-fibre wound fused, unvarnished, bare, or enamelled rectangular copper winding wires with a temperature index of 155. This International Standard, developed by the International Electrotechnical Commission (IEC), is essential for manufacturers, suppliers, and users of electrical equipment that require quality winding wire solutions with enhanced mechanical and electrical performance in demanding environments.
The standard defines the range of nominal conductor dimensions as:
- Width: 2.0 mm to 16.0 mm
- Thickness: 0.80 mm to 5.60 mm
It is part of the IEC 60317 series, which deals with specifications for various types of winding wires used in electrical equipment.
Key Topics
Material and Construction
- Base Material: Rectangular copper conductor
- Covering: Wound with a combination of polyester and glass-fibre yarn, which is fused but unvarnished
- Variants: Available as bare or with enamel insulation in grade 1 or grade 2
Temperature Index
- Rating: The wires have a temperature index of 155, making them suitable for use in applications requiring moderate thermal resistance.
Testing and Requirements
- IEC 60317-60-1 references general test methods and requirements from IEC 60317-0-8.
- Certain tests such as heat shock, cut-through, resistance to abrasion, solvents, and refrigerants are deemed inappropriate for this type of wire.
Dimensional Range
- Widths and thicknesses are specified for consistent manufacturing and application compatibility.
Grades and Combinations
- Wires may be supplied bare or enamelled (grade 1 or 2) and may have one or two layers of glass-fibre covering, with the specific build (PG1, PG2) determined by application requirements.
Applications
IEC 60317-60-1:2020 is widely used in industries where reliable winding wires are critical, especially in demanding electrical, electromechanical, and power device applications. Typical uses include:
- Transformers: Ensures wire integrity and insulation even at elevated operating temperatures.
- Motors and Generators: Provides mechanical strength and thermal stability for windings exposed to dynamic stresses.
- Coils for Industrial Electronics: Suitable for high-reliability coils in instrumentation and control equipment.
- Specialty Electromagnets: Supports requirements for insulation and physical durability in custom electromagnetic devices.
The use of polyester glass-fibre wound wires offers enhanced resistance to mechanical stress, making them ideal for challenging operational conditions where vibration, flexing, or abrasion might occur.
