The enameled copper strip is a kind of cable, and its specifications are expressed in terms of the diameter of the bare copper wire, and the unit is mm. The measurement of the enameled wire specification is actually the measurement of the diameter of the bare copper wire, generally measured with a micrometer, and its accuracy can reach 0.01mm. There are direct measurement methods and indirect measurement methods for the measurement of enameled wire specifications.
enameled rectangular aluminum wire should be measured three times with different numbers or parts no matter it is direct measurement method or indirect measurement method to ensure accurate measurement. If there is a big difference between the three measurements, it may be a parallel wire, which should be carefully analyzed. Regardless of the measurement, the wire must be straightened before the measurement to ensure the accuracy of the measurement. When the three measurement data differ greatly, it may be caused by the line not being straightened. In addition, the direct measurement method is used for the measurement of the old wire, and the indirect measurement method is used for the measurement of the new winding, which will be convenient and fast.
