Specifications for particular types of winding wires - Part 46: Aromatic polyimide enamelled round copper wire, class 240

IEC 60317-46:2013 specifies the requirements of enamelled round copper winding wire of class 240 with a sole coating of aromatic polyimide resin. The range of nominal conductor diameters covered by this standard is: - grade 1: 0,020 mm up to and including 2,000 mm; - grade 2: 0,020 mm up to and including 5,000 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - deletion of the 'in some countries' statement in the scope; - new subclause containing general notes on winding wire, formerly a part of the scope; - new subclause containing requirements for appearance; - revision to the notes in Clause 19, Dielectric dissipation factor; - new Clause 23, Pin-hole test. Keywords: requirements of enamelled round copper winding wire, class 240, sole coating of aromatic polyimide resin

Overview

EN 60317-46:2014 (IEC 60317-46:2013) specifies the requirements of enamelled round copper winding wire, class 240, with a sole coating of aromatic polyimide resin. It is a technical revision (second edition) that replaces the 1997 edition and is intended for insulated wires used for windings in electrical equipment. The standard covers nominal conductor diameters for two grades:

• Grade 1: 0.020 mm up to and including 2.000 mm
• Grade 2: 0.020 mm up to and including 5.000 mm

Class 240 denotes a thermal class requiring a minimum temperature index of 240 and a minimum heat shock temperature of 260 °C. EN 60317-46 is to be read in conjunction with IEC 60317-0-1:2013 (general requirements for enamelled round copper wire).

Key Topics and Requirements

• Material & coating: Sole coating of aromatic polyimide resin on round copper conductor.
• Thermal performance: Temperature index ≥ 240 and heat shock temperature ≥ 260 °C.
• Dimensions & electrical properties: Conductor diameters, electrical resistance and continuity requirements reference IEC 60317-0-1.
• Mechanical properties: Tests for elongation, springiness, flexibility, adherence (peel test uses K = 90 mm), cut-through and resistance to abrasion.
• Electrical tests: Breakdown voltage, dielectric dissipation factor (notes revised), continuity of insulation.
• Chemical & process resistance: Resistance to solvents, refrigerants, transformer oil; solderability; heat or solvent bonding.
• Quality & inspection: New subclause for appearance and a new pin‑hole test (Clause 23). Also includes loss of mass and packaging requirements.
• Test method references: Test methods are defined in IEC 60851 series and general wire requirements in IEC 60317-0-1.

Applications

EN 60317-46 applies to enamelled round copper winding wire used in electrical windings where class 240 thermal performance and a robust aromatic polyimide enamel are required. Typical application areas include windings in motors, transformers, coils and other electrical equipment exposed to elevated temperatures or demanding thermal cycles. The standard ensures consistent material, mechanical and electrical performance for manufacturing, testing and design.

Who uses this standard

• Manufacturers of enamelled winding wire and copper products
• Motor, transformer and coil designers specifying high-temperature wire (class 240)
• Quality assurance and testing laboratories performing conformity and type tests
• Procurement and compliance teams requiring clear material and test criteria

Related Standards

• IEC 60317-0-1:2013 - General requirements for enamelled round copper wire (normative reference)
