What are the regulations for control cable lines?

I. What are the provisions of the control cable line? The common problems of control cable lines include destruction of mechanical equipment, destruction of insulation, moisture return of insulation, brittle deterioration of insulation, over-voltage, over-temperature of the cable line and so on. When the line produces the said common faults, the switching power supply of the common fault control cable should be disconnected, the common fault points should be searched for, and the common faults should be carried out on a regular basis to check and analyze the common faults, and then carry out the overhaul and testing. The power supply system can be repaired only after fault detection. When the control cable crosses each other type, the high voltage cable line should be smaller than the cable line. When the control cable crosses the rebirth railroad line or road, need to wear pipe maintenance, maintenance pipe should be outreach road track or ground 1 m. Control cable and building basic middle spacing should ensure that the cable line buried in the building sprinkler outside; cable line imported into the building, should be based on the pipeline to carry out the maintenance, maintenance pipe should also be more than the building's outer field.
