Specifications for particular types of winding wires - Part 36: Solderable polyesterimide enamelled round copper wire, class 180, with a bonding layer

IEC 60317-36:2013 specifies the requirements of solderable enamelled round copper winding wire of class 180 with a dual coating. The underlying coating is based on polyesterimide resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is a bonding layer based on a thermoplastic 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 diameters covered by this part is:  - Grade 1B: 0,020 mm up to and including 1,600 mm;  - Grade 2B: 0,020 mm up to and including 1,600 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 1992, Amendment 1:1997 and Amendment 2:1999. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:  - new 3.2.2 containing general notes on winding wire, formerly a part of the scope;  - revision to references to IEC 60317-0-1:2013 to clarify that their application is normative;  - consolidation of 17.1 and 17.2 of the solderability requirements;  - new Clause 23, Pin hole test. Keywords: requirements of solderable enamelled round copper winding wire, class 180, dual coating

Overview

EN 60317-36:2014 (identical to IEC 60317-36:2013) specifies the requirements of solderable enamelled round copper winding wire, class 180, with a dual coating. The wire combines a polyesterimide-based underlying enamel (which may be chemically modified while retaining its identity) with a thermoplastic bonding layer on top to provide solderability and bonding for winding applications. The standard covers nominal conductor diameters for Grade 1B and Grade 2B from 0.020 mm up to and including 1.600 mm and replaces earlier editions with a technical revision.

Key topics

EN 60317-36 defines mechanical, electrical and processing requirements and normative test methods (often referencing IEC 60317-0-1:2013 and IEC test series). Major technical topics include:

• Coating chemistry and construction
  • Polyesterimide underlying enamel (modifiable within limits)
  • Thermoplastic bonding (solderable) top layer - dual coating (bonding layer)
• Dimensional and conductor requirements
  • Nominal diameters per IEC 60317-0-1
• Electrical and mechanical properties
  • Electrical resistance, elongation, springiness, flexibility and adherence
  • Breakdown voltage and continuity of insulation
• Thermal and aging characteristics
  • Temperature index and resistance to refrigerants and transformer oil
• Processing and assembly performance
  • Solderability (consolidated requirements)
  • Heat and solvent bonding performance (coil bond strength)
  • New pin hole test (Clause 23) to detect coating defects
• Durability and resistance tests
  • Heat shock, cut-through, resistance to abrasion and solvents, dielectric dissipation factor, loss of mass

Applications

This standard is targeted at components and processes where reliably solderable insulated copper windings are required:

• Manufacturers of motors, transformers, inductors, relays and solenoids that require solderable enamel for assembly
• Winding wire producers specifying product performance, coating system and diameters
• Design and procurement engineers selecting class 180 winding wire with a bonding layer for automated or manual soldering and bonding processes
• Test laboratories and certification bodies performing acceptance and conformity testing

Practical benefits include predictable solderability, defined bonding strength for heat/solvent bonding, uniform insulation performance, and compatibility with automated winding and soldering processes.

Related standards

• IEC/EN 60317-0-1:2013 - General requirements for enamelled round copper wire (normative reference)
• IEC 60851 series - Test methods for winding wires
• IEC 60264 series - Packaging of winding wires
• Other parts of the IEC 60317 series covering alternative wire types and classes
