In the process of using electricity, although people have noticed that the size of the cross-sectional area of the power cord material has an impact on the safe use of electricity, they often pay insufficient attention to the use of insulating tape for the joints. The laying of power lines is becoming more and more complicated, and it can be found under the wooden floor, in the wall, in the partition, and in the damp ground or water. If the insulation tape is used improperly, electric leakage will occur, endangering personal safety. Therefore, we must use insulating tape correctly. The power cord connectors are divided into “+” word connection, “-” word connection, and “T” word connection. The joint should be tightly wound, smooth and free of burrs. Otherwise, before the thread is disconnected, first use wire cutters to press it lightly, then wind to the pressure port, and then swing left and right, the thread will be compliantly disconnected at the joint. If the joint is in a dry place, first wrap 2 layers of insulating black tape, then 2 layers of plastic tape, and then stretch it about 200% with insulating self-adhesive tape, wrap 2 to 3 layers, and finally wrap 2 layers of plastic tape.
