DANSK DSF/PREN IEC 60317-27-4 PDF

This part of IEC 60317 specifies the requirements of paper tape covered rectangular aluminium winding wires. This covering consists of two or more layers of paper tape and is primarily intended for winding coils for oil immersed transformers. The range of nominal conductor dimensions covered by this standard is: – width: min. 2,00 mm max. 16,0 mm; – thickness: min. 0,80 mm max. 5,60 mm. The paper tapes included in this standard are restricted to those specified in IEC 60554-1 and IEC 60554-3-5. NOTE – IEC TC 15 is investigating the incorporation of requirements in IEC 60641 for presspaper and pressboard into IEC 60554.
