This part of IEC 6031 7 specifies requirements for tape wrapped rectangular copper winding wire of temperature index 220. The insulation consists of one or more wrappings of aromatic polyamide (aramid) tape of various thicknesses.
NOTE The heat shock test is inappropriate for this type of wire, and therefore a heat shock temperature cannot be established. Consequently, a class based on the requirements for temperature index and heat shock temperature cannot be specified.
The range of nominal conductor dimensions covered by this standard is:
– width: min. 2,00 mm max. 1 6,00 mm;
– thickness: min. 0,80 mm max. 5,60 mm.
The specified combinations of width and thickness as well as the specified ratio width/thickness are given in Table 1 .
