Operation and maintenance of wire and cable

[Abstract]:

(1) corrosion monitoring. The surrounding soil near the line should be measured with a special instrument. If it belongs to the anode area, corresponding measures should be taken to prevent electrolytic corrosion of wire and cable metal bushing. The wetting soil around it or the soil covered by domestic refuse often occurs chemical corrosion and microbial corrosion. According to the voltage value in the anode area, proper cathodic protection measures or drainage devices are selected.
(2) insulation supervision. According to the importance of each cable and wire, a preventive test plan is made, and the weak links are found in time to eliminate the defects that may occur. In general, after the preventive test, the external protection layer is also required for the direct current voltage test, as well as the detection and elimination of the defects of the outer protective layer.
(3) load monitoring. Generally, the maximum current value is stipulated according to the sectional area and insulation type of conductor. The main load monitoring measures are measured by various instruments, such as load current or electric skin temperature, so as to prevent the insulation from exceeding the allowable maximum temperature and shorten the cable life.
(4) temperature monitoring. Measurement of temperature should be carried out in summer or at maximum load. When measuring the temperature of a directly buried wire and cable, the temperature of the soil with no other heat source in the same area should be measured.
