IEC 60317-7:1997 PDF

Scope: This International Standard specifies the requirements of enamelled round copper winding wire of class 220 with a sole coating based on polyimide resin. Class 220 is a thermal class that requires a minimum temperature index of 220 and a heat shock temperature of at least 240 ℃. 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, inclu-ding the type of equipment involved. The range of nominal conductor diameters covered by this standard is: - Grade 1: 0,020 mm up to and including 2,000 mm; - Grade 2: 0,020 mm up to and including 5,000 mm. The nominal conductor diameters are specified in clause 4 of IEC 60317-0-1.
