What is BS EN 60317-40 –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. The main objective of the BS EN 60317 series is to ensure winding wires offer optimum electric strength and service life, and to minimize risk of product failure.
BS EN 60317-40 is the 40th part of the multi-series that specifies the requirements of glass-fibre braided impregnated, bare, grade 1 or grade 2 enamelled rectangular copper winding wire, temperature index 200.
NOTE: For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot be established. Consequently, a class based on the requirements for temperature index and heat shock temperature cannot be specified.
Who is BS EN 60317-40- Enamelled rectangular copper winding wire for?
BS EN 60317-40 for particular types of winding wires is relevant to:
- Manufacturers of winding wires
- Manufacturers of electrical applications such as generators, transformers, etc
- Manufacturers of enamelled rectangular copper wire
- Manufacturers of wire insulation materials
- Electrical engineers
- Product design engineers
Why should you use BS EN 60317-40- Enamelled rectangular copper winding wire?
Copper is used as an electrical conductor in many types of wiring. Copper wire is used in a variety of applications, including power generation, transmission, and a variety of other electrical equipment.
BS EN 60317-40 provides you with the range of nominal conductor diameters based on wires of two grades. Reference standard for test methods to assess properties such as electrical resistance, elongation, flexibility and heat shock, amongst others, are also covered.
Adopting the specifications for the particular type of winding wire in compliance with BS EN 60317-40 can ensure its properties remain intact for the optimal insulation and performance of your specific electrical application.
This can help make the right production decisions to ensure durability and long service life of enamelled rectangular copper wires, and achieve the necessary electrical strength.
What’s changed since the last update?
BS EN 60317-40:2015 supersedes BS EN 60317-40:1995 which is withdrawn. This edition includes the following significant technical changes with respect to the previous edition:
- Revision to Clause 2, Normative references
- New 3.2.2 contains general notes on winding wire, formerly a part of the scope
- Revision to references to IEC 60317-0-5 to clarify that their application is normative
