Specifications for particular types of winding wires - Part 22: Polyester or polyesterimide enamelled round copper wire overcoated with polyamide, class 180
Specifications for particular types of winding wires - Part 22: Polyester or polyesterimide enamelled round copper wire overcoated with polyamide, class 180
IEC 60317-22:2004+A1:2009 specifies the requirements of enamelled round copper winding wire of class 180 with a dual coating.
The underlying coating is based on polyester or polyesterimide resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is based on polyamide resin.
Class 180 is a thermal class that requires a minimum temperature index of 180 and a heat shock temperature of at least 200 °C. The temperature in degrees Celsius corresponding to the temperature index is not necessarily that at which it is recommended that the wire be operated and this will depend on many factors, including the type of equipment involved.
The range of nominal conductor diameters covered by this standard is as follows:
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1.
The main changes with respect to the previous edition are listed below:
This consolidated version consists of the third edition (2004) and its amendment 1 (2009). Therefore, no need to order amendment in addition to this publication.
