Find a similar 240 cable about 2M~5M long (of course the length depends on the length of the cable loss). Normally, after the cable laying is completed, nothing will be left in the cable trench or trough. Margin, so if the cable is damaged by external force, it is usually not long enough, so a section of cable of the same specifications must be prepared for connection. Then prepare enough terminal heads for making intermediate joints, which can be said to be copper pipes. Start wiring: 1. Check the color code (continued)
2. Then put a large heat shrink sheath on the outermost layer of the cable, and then put the heat shrink sheath of the corresponding color on each phase. Sheath
3. Crimp the middle joint
4. After the middle joint is pressed, wrap the self-adhesive waterproof tape around it, and wrap it all with overlap. The thickness is based on the thickness of each phase on the back. The colored heat-shrinkable sheath just fits.
5. For the first heat shrinkage, heat shrink the colored heat shrinkable sheath on each phase. After completion, use the remaining temperature to wrap the self-adhesive waterproof tape and wrap the heat shrink sheath tightly.
6. Wrap each phase with plastic tape.
7. After bandaging, put the large heat-shrinkable sheath originally put on the outer layer of the cable at the middle joint and heat-shrink it.
8. After heat shrinking, wrap the middle joint with waste cable sheath and fix it with tape for protection.
With such a good joint, there will usually be no problems.
