Overview

EN 60317-68:2017/A1:2019 is a European standard that specifies requirements for polyvinyl acetal enamelled rectangular aluminium wire, class 120. Developed by CLC under the framework of the International Electrotechnical Commission (IEC), this standard forms Part 68 of the series on particular types of winding wires. It defines the technical and chemical characteristics of aluminium winding wire coated with a single enamel based on polyvinyl acetal or polyvinyl formal resin, used in electrotechnical applications.

This amendment (A1:2019) updates the 2017 edition by clarifying resin types covered and ensuring alignment with international technical requirements. The standard ensures uniformity and quality consistency across European markets, fostering compatibility and interchangeability of winding wires in electrical machinery.

Key Topics

• Material Specification:
  The wire is rectangular aluminium with an enamel coating based on polyvinyl acetal or polyvinyl formal resin. The resin may be modified chemically but must retain its original identity and meet strict physical and electrical properties for class 120.

• Thermoplastic Resin Details:
  Polyvinyl acetal represents a family of thermoplastic vinyl resins synthesized by condensing polyvinyl alcohol with an aldehyde. This family includes polyvinyl butyral and polyvinyl formal, offering a range of insulation and mechanical properties suited for winding wires.

• Electrical Class 120:
  The enamelled wire falls under insulation class 120, corresponding to thermal endurance and electrical performance suitable for operating temperatures up to 120°C.

• Standard Compliance and Implementation:
  The document is harmonized with IEC 60317-68:2017/A1:2019 globally and mandates national adoption by EU countries, facilitating market consistency and compliance.

Applications

EN 60317-68:2017/A1:2019 aluminium winding wires are primarily used in:

• Electrical Machines:
  Application in stator and rotor windings of motors, generators, and transformers requiring insulation materials with reliable thermal and dielectric properties.

• Electromechanical Components:
  Utilized in coils, relays, solenoids, and inductors where compact rectangular wire geometry improves winding density and efficiency.

• Energy-Efficient Equipment:
  Aluminium rectangular wires provide a lightweight alternative to copper with excellent conductivity and enamel insulation suitable for class 120 thermal rating.

• Industrial Manufacturing:
  Standardized wire ensures interoperability in large-scale production of electrical components where quality and uniformity are critical.

Related Standards

• IEC 60317 Series:
  Covers various enamelled winding wires, providing international benchmarks for different wire shapes, materials, and insulation classes.

• EN 60317-68 (Base Standard):
  The foundation document specifying winding wires coated with polyvinyl acetal enamel; this amendment updates that specification.

• INSULATION CLASS STANDARDS:
  Related standards define testing methods and classification of insulating materials by temperature and electrical endurance to ensure compatibility and safety.

• Aluminium Product Standards:
  Industry standards regulating the chemical and mechanical properties of aluminium materials used in electrical applications.
