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 60317-72 is the 72nd part of multi-series specifies the requirements of polyester glass-fibre wound, resin or varnish impregnated bare, grade 1 or grade 2 enamelled rectangular copper winding wires, 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.
BS EN IEC 60317-72 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.
BS EN IEC 60317-72 includes winding wires with fibre covering of a combination of polyester and glass fibres and provides six grades of thickness for coatings.
BS EN IEC 60317-72 covers appearance and dimension parameters, the assessment of which is essential to determine whether electrical properties are compromised. You can find the reference standard for these specifications in BS EN IEC 60317-72.
Adopting the specifications for the particular type of winding wire in compliance with BS EN IEC 60317-72 will ensure properties such as mechanical strength, temperature and heat resistance remain intact for the optimal performance of your specific application. This can help make the right production decisions based on thickness and grades, to ensure durability and long service life of rectangular copper winding wires.
