This part of IEC 60317 forms an element of a series of standards which deals with insulated wires used for windings in electrical equipment.
BS EN IEC 60317-73 is the 73rd part of a multi-series that specifies the requirements of enamelled rectangular aluminum winding wire of class 200 with a dual coating. The underlying coating is based on polyester or polyesterimide resin, which can be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. 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 IEC 60317-73 on 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. In this regard, polyester or polyesterimide resin-based coating on wires is critical for electrical insulation purposes.
BS EN IEC 60317-73 provides you with the range of nominal conductor diameters based on two grades. You can also find the values for resistance to abrasion for these two grades along with reference to standards for recommended dimensions, temperature index, electrical resistance, elongation, appearance, and flexibility.
As a manufacturer, compliance with BS EN IEC 60317-73 ensures polyester or polyesterimide rectangular aluminium winding wires offer high resistance to heat and ductility, thus enhancing performance of the end-application. With best industry practices recommended by BS EN IEC 60317-73, you can make the right production decisions based on thickness and grade, to ensure durability and the long service life of polyester or polyesterimide rectangular aluminium wires.
