GB 7947-1997 stipulates the standard for conductor Color or digital identification. The standard clarifies the color and digital identification rules corresponding to different types of conductors, unifies the conductor identification method, and facilitates the quick distinction of conductor functions and uses in the installation and maintenance of electrical systems. It avoids electrical failures or safety hazards caused by confusion of identification, and provides a technical basis for the standardization and accuracy of conductor identification in the electrical industry.
