What is BS EN 60317552018

Introduction

The BS EN 60317-5-5:2018 is a technical standard that focuses on the specifications and requirements for the enamelled round and rectangular copper winding wires. This article aims to provide a thorough understanding of this standard, explaining its significance in various industries and highlighting key points regarding the wire's manufacturing process, properties, and testing.

Manufacturing Process

The manufacturing process of enamelled copper winding wires involves several essential steps. It begins with the selection of high-quality copper rods, which are then drawn into the desired diameter. The next step involves cleaning the copper surface to remove any impurities. Subsequently, an enamel coating is applied to the wire by either an extrusion method or through various dipping processes. The coated wire is then cured at high temperatures to ensure proper adhesion of the enamel.

Properties and Specifications

The BS EN 60317-5-5:2018 standard defines specific properties and requirements for enamelled copper winding wires. These properties include thermal class, conductor resistance, mechanical properties, insulation thickness, and breakdown voltage among others. The standard ensures that the wire's performance is reliable and consistent across different applications and environments. It provides guidance on the permissible deviations in dimensions and tolerances for various wire sizes.

Testing and Compliance

To ensure compliance with the BS EN 60317-5-5:2018 standard, manufacturers perform rigorous testing on the enamelled copper winding wires. Various tests are conducted to assess properties such as electrical resistance, thermal endurance, coating abrasion resistance, flexibility, and adhesion strength. Compliance with this standard signifies that the wire meets the necessary requirements for optimal performance and safety.
