What is BS EN 60317-57 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 IEC 60317 series is to ensure winding wires offer optimum electric strength and service life, and to minimize risk of product failure.
BS EN 60317-57 is the 57th part of the multi-series that specifies the requirements of an enamelled round copper winding wire of class 220 with a sole coating based on polyamide-imide resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements.
Who is BS EN 60317-57 for?
BS EN 60317-57 on particular types of winding wires is relevant to:
- Manufacturers of winding wires
- Manufacturers of electrical applications such as generators, transformers, etc
- Manufacturers of polyamide-imide enamelled round copper wire
- Manufacturers of wire insulation materials
- Electrical engineers
- Product design engineers
Why should you use BS EN 60317-57?
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. In this regard, class 220 is a thermal class that requires a minimum temperature index of 220 and a heat shock temperature of at least 240 ºC.
BS EN 60317-57 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 60317-57 can ensure properties such as temperature and heat resistance remain intact for the optimal insulation and performance of your specific application.
This can help make the right production decisions to ensure durability and long service life of polyamide-imide enamelled round copper wires, and achieve the necessary electrical strength.
