What is BS EN IEC 60317-25about?
BS EN IEC 60317-25 is the 25th part of the multi-series that specifies the requirements of enamelled round aluminium winding wires of class 200 with a dual coating. The underlying coating is based on polyester or polyesterimide resin, which can be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is based on polyamide-imide resin.
Who is BS EN IEC 60317-25for?
BS EN IEC 60317-25 on specification of aluminium winding wires is relevant to:
- Aluminium wire manufacturers
- Manufacturers of applications that require electrical transference
- Electrical engineers
- Mechanical engineers
Why should you use BS EN IEC 60317-25?
Enamelled aluminium wire is an insulated electrical conductor used in motors, transformers, and other electromagnetic equipment.
BS EN IEC 60317-25 is useful as it provides specifications of wires that are safe to use and are more resistant to heat than conductive metals.
BS EN IEC 60317-25 provides you with methods to obtain high performance wires with high resistance to heat and optimal electrical conductivity. These features make the wires more durable to perform under extreme conditions.
What’s changed since the last update?
BS EN IEC 60317-25:2020 supersedes BS EN 60317‑25:2010, which is withdrawn. Some of the changes are:
- New 3.2.2 containing general notes on winding wire, formerly a part of the Scope
- Revision to Clause 11 to consider intermediate nominal conductor diameters
- Revision to Clause 7 to indicate that the springiness test is inappropriate
- Revision to Clause 16 to specify only the percentage of extractable matter and the minimum retained dielectric breakdown voltage
