IEC 60317-68:2017+A1:2019 specifies the requirements of enamelled rectangular aluminium winding wire of class 120 with a sole coating based on polyvinyl acetal resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The range of nominal conductor dimensions covered by this standard is
Width: minimum 2,0 mm and maximum 16,0 mm
Thickness: minimum 0,80 mm and maximum 5,60 mm
Wires of grade 1 and grade 2 are included in this part of IEC 60317 and apply to the complete range of conductors. The specified combinations of width and thickness as well as the specific ratio width/thickness are given in IEC 60317-0-9:2015. This consolidated version consists of the first edition (2017) and its amendment 1 (2019). Therefore, no need to order amendment in addition to this publication.
