Common faults of control cable lines include mechanical damage, insulation damage, insulation moisture, insulation aging deterioration, overvoltage, and cable overheating. When the above faults occur in the line, the power supply of the faulty cable should be cut off, the fault should be found, the fault should be inspected and analyzed, and then repaired and tested. The power supply can be restored only after the fault is eliminated.

Tianxing Cable tells you what the safety requirements are for buried control cables

Safety requirements for buried control cables

1, when the cable lines cross each other, the high voltage cable should be under the low voltage cable. If one of the cables is protected by pipes or separated by a partition within 1m before and after the crossing point, the minimum allowable distance is 0.15m.

2. When the cable is close to or crossed with the heat pipeline, if there are insulation measures, the small distance between parallel and cross is 0.5m and 0.15m respectively.

3, cable and railway or road crossing should be through the tube protection, the protection tube should extend out of the track or road surface 2m.

4, the distance between the cable and the building foundation, should be able to ensure that the cable buried in the building outside the water; When the cable is introduced into the building, it should be protected through the pipe, and the protection pipe should also be beyond the building water.

5, directly buried in the ground cable and the ground of the general grounding device should be 0.15~0.5m apart; The buried depth of the cable directly buried in the ground should not be less than 0.7m, and should be buried under the frozen soil layer.
