Operation method of insulating tape

In the process of using electricity, although people have noticed that the cross-sectional area of power cord materials has an impact on the safe use of electricity, they often do not pay enough attention to the use of insulation tape for joints. The laying of power lines is becoming increasingly complex, including under wooden floors, in walls, in partitions, and in damp underground or underwater environments. If the insulation tape is not used properly, electric leakage will occur, endangering personal safety. So we need to use insulation tape correctly, and the power line joints can be connected using "+", "-", "T", etc. The joint should be tightly wrapped, smooth and free of burrs. Otherwise, before disconnecting the wire head, it should be lightly pressed with a steel wire pliers, then wound to the pressure mouth, and then left and right swing. The wire head will disconnect smoothly at the joint. If the joint is in a dry place, it should be wrapped with 2 layers of insulating black tape first, followed by 2 layers of plastic tape. Then, the insulating self-adhesive tape should be stretched by about 200%, wrapped in 2-3 layers, and finally wrapped in 2 layers of plastic tape.
