What is BS EN 60317-47 – Polyimide enamelled rectangular copper winding wire about?
This part of IEC 60317 forms an element of a series of standards that deals with insulated wires used for windings in electrical equipment.
BS EN IEC 60317-47 is the 47th part of the multi-series that specifies the requirements of enamelled rectangular copper winding wire of class 240 with a sole coating of aromatic polyimide resin.
Who is BS EN 60317-47 - Polyimide enamelled rectangular copper winding wire for?
BS EN 60317-47 on particular types of winding wire is relevant to:
- Copper wire manufacturers
- Manufacturers of applications that require electrical transference
- Manufacturers of electrical applications
- Telecommunication organisations
- Electrical engineers
- Mechanical engineers
Why should you use BS EN 60317-47 - Polyimide enamelled rectangular copper winding wire?
Winding wires are largely used in the construction of applications such as transformers, motors, and generators. The main purpose of a winding wire is to interchange electrical energy with magnetic energy.
BS EN 60317-47 includes guidance on winding wires with fibre covering of a layer of polyimide that provides two grades of thickness for coating.
BS EN 60317-47 covers appearance and dimension parameters, elongation, springiness the assessment of which is essential to determine whether electrical properties are compromised.
Adopting the specifications for the particular type of winding wire in compliance with BS EN 60317-47 will ensure properties such as mechanical strength, temperature and heat resistance remain intact for the optimal performance of your specific application. This can help make the right production decisions based on thickness and grades, to ensure durability and the long service life of rectangular copper winding wires.
