PVC electrical insulation tape '> principle of PVC electrical insulation tape: There are many defects in direct application of plastic tape: plastic tape is easy to be misplaced and opened when it is long; When the electrical appliance is under heavy load, the joint heats up and the plastic adhesive tape is easy to melt and Shorten; The power connectors are kneaded with each other in the junction box. When the connectors have burrs, it is very simple to puncture the plastic tape. These hidden dangers will directly endanger personal safety, cause short circuits and form fires. However, the above situation will not be presented by using insulating black adhesive tape. It has certain strength and flexibility, can be tightly wrapped around the joint for a long time, is tightly shaped by the influence of time and temperature, and will not fall off, and flame retardant. In addition, wrapped with insulating black tape and then wrapped with plastic tape can prevent moisture and rust. Of course, the insulating self-adhesive tape also has defects. Although it has good waterproof function, it is easy to break. Therefore, it is necessary to wrap two layers of plastic adhesive tape as a protective layer. The insulating self-adhesive tape of the joint and the joint is not sticky to each other and has better function. Operation method of PVC electrical insulation tape: in the process of using electricity, although people have noticed that the cross-sectional area of power cord data has an impact on the safe use of electricity, they often do not pay attention to the application of insulation tape to joints. The laying of power lines is becoming more and more messy, walking under the wood floor, in the wall, in the partition and in the wet underground or in the water. If the insulating tape is not properly used, it will leak electricity and endanger personal safety. Therefore, we must correctly use the insulating tape, the power cord connector is divided into '' Word connection method, '-'Word connection,' T 'word connection, etc. The joint should be tightly wrapped and lubricated without burrs. Otherwise, before the line head is disconnected, it should be lightly pressed with a wire cutter, then wound to the pressure opening, and then left and right, the thread will be disconnected at the joint. If the joint is in a dry place, first wrap 2 layers with insulating black tape, then wrap 2 layers with plastic tape, and then use insulating self-adhesive tape to lengthen about 200% and wrap 2 ~ 3 layers, wrapped with 2 layers of plastic tape.
