1. Starting point for wrapping PVC electrical tape

The starting point of PVC electrical tape is very important. If the starting point of PVC electrical tape is not well selected, it will not only waste electrical tape, but may also affect the final effect of electrical tape. Generally speaking, the wrapping starting point of PVC electrical tape should be 1-2 cm of the wrapping position where the copper wire or aluminum wire is exposed on the line.

2. Surrounding method of PVC electrical tape

Different line joints have different PVC electrical tape surrounding effect methods. According to the wiring method, the surrounding methods of PVC electrical tape include "ten" surrounding connection, "one" surrounding connection, "D" surrounding connection, etc. . Therefore, you must pay attention to the corresponding wrapping method before wrapping the PVC electrical tape.

3. Perform the wrapping operation correctly according to the wrapping method of PVC electrical tape

After understanding the wrapping starting point and wrapping method of PVC electrical tape, electricians can perform wrapping operations. In the wrapping process, they must follow the correct wrapping method.

Take the "one" line connector as an example. When using PVC tape, after ensuring that the beginning of the PVC tape is flat, surround the past from the interspersed end of the wiring diagram to the other end, and try to force the PVC electrical tape to wrap around the line as hard as possible. On the way. Ensure that the PVC electrical tape will not loosen or loosen during the effective period after use.

4. Precautions when wrapping PVC electrical tape

PVC electrical tape cannot directly affect the line joints when it is surrounded. PVC electrical tape is generally used together with electrical insulating black tape. Generally, when wrapping, first use electrical insulating black tape to wrap 2-3 layers on the wire head, and then use PVC electrical tape to wrap 2-3 layers again, and repeat the loop twice to complete the wrapping operation. At the same time, the strength of the surrounding should be maintained as much as possible during the surrounding process, so as to ensure that the PVC electrical tape will not spread, peel off and other phenomena.
