The main function of PVC electrical tape is to insulate, bind and fix the circuit and line. Therefore, the protective characteristics of PVC electrical tape should be highlighted when using PVC electrical tape. The correct use method of PVC electrical tape is determined according to the specific protection effect and the type of power cord. However, in general, the correct use method and process of PVC electrical tape should be as follows:
1. Determine the wrapping starting point of PVC electrical tape
It is very important to specify the wrapping starting point of PVC electrical tape. If the wrapping starting point of PVC electrical tape is not properly selected, it will not only cause waste of PVC electrical tape, but also may affect the effect of the end Z of PVC electrical tape. Generally speaking, the wrapping starting point of PVC electrical tape shall be 1-2 cm of the sheath where the copper wire or aluminum wire is exposed.
2. Define the winding method of PVC electrical tape
Different line joints have different winding methods of PVC electrical tape. According to the connection method of the line, the winding methods of PVC electrical tape also include "cross" winding method, "one" winding method, "T-" winding method, etc. Therefore, we must pay attention to the corresponding winding method before winding PVC electrical tape.
3. Perform winding operation correctly according to the winding method of PVC electrical tape
Only after the wrapping starting point and winding method of PVC electrical tape are clear, can the electrician carry out the winding operation. During the winding process, pay attention to the correct winding method.
Take the "I-shaped" line connector as an example. When using PVC tape, after ensuring the flatness of the PVC tape at the beginning, wind it from the cross end of the wiring diagram to the other end, and use as much force as possible to make the PVC electrical tape tightly wound on the line. Ensure that the PVC electrical tape will not become loose or loosened within its effective period after use.
4. Precautions for winding PVC electrical tape
When PVC electrical tape is wound, it cannot directly act on the line joint. PVC electrical tape is generally used together with electrical insulating black tape. Generally, the electrical insulating black tape is used to wind 2-3 layers on the wire head first, and then PVC electrical tape is used to wind 2-3 layers again. In this way, the winding operation is completed after repeated winding twice. At the same time, the winding strength shall be maintained as much as possible during the winding process to ensure that the PVC electrical tape will not stretch, release and other phenomena.
