Can PVC electrical tape directly touch wires?

 PVC electrical tape can directly contact wires. PVC electrical tape is used for 380v wires. Normally, the electrical tape used in single-phase tape is 220V. In fact, each pair of 380V wires is also 220V. PVC electrical tape is divided into high pressure tape and low pressure tape. And distinguish waterproof tape and ordinary tape.

How to use PVC electrical tape?



Before the thread is disconnected, the thread should be pressed lightly with the wire pliers, and then wound to the mouth, and then swing left and right, and then the thread will be smoothly disconnected at the joint. If the joint is in a dry place, it should be wrapped in two layers of insulating black cloth, then two layers of plastic tape (also called PVC adhesive tape), and then two or three layers of insulating self-adhesive tape stretched by about 200%. Two layers of plastic tape. Because if the plastic tape is used directly, there are more certainties: the plastic tape is prone to dislocation of the raw rubber and the time of the glue opening for a long time. When the electrical load is heavy, the joint will generate heat, and the plastic electrical tape is easy to melt and shrink. The power connectors are pressed against each other in the junction box. When the connectors have burrs, it is easy to puncture the plastic tape. These hidden dangers directly endanger personal safety, cause short circuits or find abnormalities, and cause fires.

However, the above situation will not occur with the use of PVC electrical tape. Because it has a certain strength and flexibility, it can be tightly wrapped around the joint for a long time, and it will be dry and fixed under the influence of time and temperature, will not fall off, and it is flame-retardant. In addition, the use of insulating black tape and then tape can have the characteristics of moisture-proof and rust-proof.

Therefore, learn how to use PVC electrical tape and use it correctly to prevent leakage and reduce harm.
