IEC 60317-52:2014 specifies requirements for tape wrapped round copper winding wire of temperature index 220. The insulation consists of one or more wrappings of aromatic polyamide (aramid) tape of various thicknesses. The range of nominal conductor diameters covered by this standard is: – 1,600 mm up to and including 5,000 mm; – the nominal conductor diameters are given in Table 1. This second edition cancels and replaces the first edition published in 1999. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – new 3.2.2 containing general notes on winding wire, formerly a part of the scope; – new 3.3, containing requirements for appearance; – modification to Clause 15 to delete the note on revisions to IEC 60172; – new Clause 23, Pin hole test. Keywords: tape wrapped round copper winding wire of temperature index 220, aromatic polyamide (aramid) tape<\/p>\n
