Abstract: With the increasing requirements of enterprise informatization, standardization and lean management, the name tag of electrical equipment has become an important link for managers and front-line production personnel to be familiar with the technical parameters of equipment, master the operation track of equipment and ensure the safe and assured operation of equipment. Most of the traditional cable hangtags are made of PVC. In the process of use, the hangtag will be burned after fire. The traditional cable hangtag has a small area and can not express more content except the basic information of the cable. Strengthen the proper installation of cable hangtag. Identify the cable identity, length, direction and running time through the tag identification. Avoid misoperation, misjudgment and other safety production accidents. Ensure the safe and reliable operation of electrical equipment. Provide reliable guarantee for the operation of production management personnel.
