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 electrical tape for the joints. Now the laying of power lines is becoming more and more complicated, and they can be found under wooden floors, in walls, in partitions, and in damp ground or water. If the insulating electrical tape is used improperly, electric leakage will occur, which may endanger personal safety. So we have to use insulating electrical tape correctly.
These hidden dangers will directly endanger personal safety, cause circuit short-circuits, and cause fires. The above situation will not occur with the use of insulating black tape, because it has a certain strength and flexibility, can be tightly wound around the joint for a long time, even if it is affected by time and temperature, it will not easy to fall off, and flame retardant. Furthermore, wrapping it with insulating black tape and then wrapping it with plastic tape can prevent moisture and rust.
