Find a similar 240 cable about 2M to 5M long (of course the length depends on the length of the cable loss). Normally, once the cable installation is complete, there will be nothing left in the trench or cable margin. So, if the cable is damaged by an external force, it is usually not long enough, so a section of cable with the same specifications must be prepared for connection. Then prepare enough terminal heads to make intermediate joints, which can be regarded as copper pipes. Start wiring: 1. Check the color code (continued)
2. Then put a large heat shrink tubing on the outermost layer of the cable, then put the heat shrink tubing of the corresponding color on each phase. . Sheath
3. Crimp the center joint
4. Once the center seam is pressed, wrap the self-adhesive waterproof tape around it and wrap the wholet with an overlap. is based on the thickness of each phase on the back. The colored heat shrink tubing fits perfectly.
5. For the first heat shrink, heat shrink the colored heat shrink tubing on each phase. When finished, take advantage of the residual temperature to wrap the waterproof tape and tightly wrap the heat shrink tubing.
6. Wrap each phase with plastic tape.
7. After bandaging, place the large heat shrink tubing originally laid on the outer layer of the cable at the middle junction and heat shrink it.
8. After heat shrinking, wrap the center joint with used cable jacket and secure it with tape to protect it.
With a seal this good, there will usually be no problems.
