What is BS EN 60317-5-8:2018

Electric wires and windings are crucial components of electrical machines and appliances. They play a significant role in ensuring the proper functioning of motors, transformers, and various industrial equipment. To maintain safety and quality standards, different regulatory bodies develop and enforce specific guidelines for the production and testing of these wire and winding products. One such important standard is BS EN 60317-5-8:2018.

Understanding BS EN 60317-5-8:2018

BS EN 60317-5-8:2018 is an international standard that sets requirements for the enameled round copper winding wires used in electrical machinery. The standard was developed by the British Standards Institution (BSI) with the aim of ensuring consistent quality and performance of these wires across the industry.

The standard specifies the dimensions, insulation materials, thermal properties, mechanical properties, and electrical properties of enameled round copper winding wires. It covers a wide range of wire sizes commonly used in electrical machines, from the ultra-thin 0.025 mm diameter up to 5.600 mm diameter.

Key Requirements of BS EN 60317-5-8:2018

BS EN 60317-5-8:2018 outlines several key requirements that manufacturers must adhere to when producing enameled round copper winding wires:

1. Dimensional Requirements: The standard specifies the permissible tolerances for the diameter and shape of the wires, ensuring consistency in size for proper fitment in electrical machines.

2. Insulation Materials: The standard defines the types of insulation materials that can be used, including polyvinyl acetal, polyesterimide, and polyurethane, among others. It also provides guidelines for the thickness and adhesion strength of the insulation layer.

3. Thermal Properties: The standard sets requirements for the maximum permissible temperature index (TI) of the wire, which determines its ability to withstand elevated temperatures without degrading its electrical and mechanical properties.

4. Mechanical Properties: BS EN 60317-5-8:2018 specifies the tensile strength, elongation, and flexibility requirements of the wire to ensure it can withstand the mechanical stresses encountered during installation and operation.

5. Electrical Properties: The standard outlines the requirements for conductivity, resistivity, breakdown voltage, and dielectric loss factor of the wire, ensuring proper electrical performance and insulation characteristics.

Benefits of BS EN 60317-5-8:2018

Adhering to BS EN 60317-5-8:2018 brings several benefits to manufacturers and end-users:

1. Consistency: The standard ensures consistent quality and performance of enameled round copper winding wires across different manufacturers, making it easier to compare and select suitable products.

2. Reliability: By following the standard's requirements, manufacturers can produce wires that have improved thermal and mechanical properties, reducing the risk of failures and increasing the lifespan of electrical machines.

3. Safety: By setting stringent requirements for insulation materials and electrical properties, BS EN 60317-5-8:2018 helps in preventing electrical hazards and ensuring the safe operation of machinery and appliances.

4. Compliance: Adhering to BS EN 60317-5-8:2018 helps manufacturers demonstrate compliance with international standards and regulations, boosting credibility and market acceptance.

In conclusion, BS EN 60317-5-8:2018 plays a vital role in ensuring the quality, performance, and safety of enameled round copper winding wires used in electrical machinery. Manufacturers must familiarize themselves with the standard's requirements and comply with them to deliver reliable and high-quality products that meet the needs of industries worldwide.
