Specifications for Particular Types of Winding Wires - Part 53: Aromatic Polyamide (Aramid) Tape Wrapped Rectangular Copper Wire, Temperature Index 220
|Publication Date:||1 April 1999|
|ICS Code (Wires):||29.060.10|
This part of IEC 60317 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 - For this type of wire, the heat shock test is inappropriate 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 temperature in degrees Celsius corresponding to the temperature index is not necessarily that at which the wire is recommended to be operated and this will depend on many factors, including the types of equipment involved.
The range of nominal conductor sizes covered by this standard is:
- width: min. 2,00 mm max. 16,00 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.
When reference is made to winding wire according to this standard, the following information should be given:
- reference to IEC 60317-53;
- dimensions of the conductor;
- reference should also be made to the number and thickness of the papers used and to the degree of overlap, as agreed between purchaser and supplier.
