This International Standard specifies the requirements of paper tape covered rectangular copper winding wires. This covering consists of two or more layers of paper tape, all in the same direction and is primarily intended for winding coils for oil immersed transformers.
The range of nominal conductor dimensions covered by this standard is
- width: min. 2,0 mm max. 16,0 mm;
- thickness: min. 0,80 mm max. 5,60 mm.
The paper tapes covered by this standard are restricted to those specified in IEC 60554-1 having thicknesses in the range 25 μm to 125 μm inclusive.
When a reference is made to winding wire according to this standard, the following information shall be given in the description:
- reference to IEC 60317-27;
- nominal conductor dimensions in millimetres (width × thickness);
- nominal increase in dimensions due to paper.
Example: IEC 60317-27 4,00 × 1,00 + 0,20
