1. First, make a visual inspection to determine the number, size and distribution of embedded points, and mark the positions. Serious need to be repaired in time.

2. Use insulation resistance meter to carry out lug test and open circuit test of cable outer shield, and check whether the shield layer is faulty.

3. Embedding is light. When the power unit is overhauled, gently pull it out or tap it for molding with a simple device. Do not use sharp tools.

4. If it is seriously buried, the damaged parts at both ends of the cable can be cut off and reconnected. Check the conductor for damage.

5. Carry out withstand voltage test after remediation to ensure that the insulation performance of the cable meets the requirements.
