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 the risk of product failure.
BS EN 60317-69 is the 69th part of a multi-series that specifies the requirements of enamelled rectangular aluminium winding wire of class 220 with a dual coating based on polyesterimide or polyester resin which can be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements.
Note: A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics.
BS EN 60317-69 on particular types of winding wires is relevant to:
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 60317-69 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 60317-69 can ensure properties such as temperature and heat resistance remain intact for the optimal performance of your specific application.
This can help make the right production decisions to ensure durability and long service life of polyamide-imide enamelled rectangular aluminium wires, to achieve the necessary electrical strength.
