This standard specifies the requirements for paper tape-covered right-angle copper wire. This covering consists of two or more layers of paper tape covered in the same direction, and is mainly used for oil-immersed transformer coil windings. The ranges of nominal conductor diameters to which this standard applies are as follows:
——Width 2.0 mm to 16.0 mm - Thickness: 0.80 mm to 5.60 mm Paper tapes to which this standard applies are specified in IEC 60554-1 and are limited to tapes with a thickness of 25 μm to 125 μm. When referring to windings according to this standard, the information below is provided in the manual. - References to this standard - Nominal conductor dimensions, millimeters (width x thickness) - Increase in nominal dimensions due to paper?
