This standard specifies the requirements for enamelled rectangular copper wire of class 120, singly coated based on polyvinyl acetal resin, which may be modified. However, the copper wire must have the chemical homogeneity of the resin prototype and meet all specified wire requirements. Classification grade 120 is a thermal grade that requires a minimum temperature index of 120 and a thermal shock temperature of 155 ℃ or higher. The corresponding temperature index is The temperature in degrees Celsius is not necessarily the recommended temperature at which the wire will run, and is determined by a variety of factors, including the type of equipment involved. The ranges of nominal conductor sizes covered by this standard are as follows:
——Width: 2.0 mm and above 16.0 mm. mm or less - Thickness: 0.80 mm or more and 5.60 mm or less. Class 1 and 2 conductors are included in this standard, which applies to the entire conductor range. The sum of specified widths and thicknesses and specified width/thickness ratios are given in IEC 60317-0-2. do.?
