The operation of power cable lines is extremely important in the entire power production process. Because the safety of cable lines is directly related to the production safety of enterprises and the safety of people’s lives and properties, it is extremely important to understand the operation and maintenance of power cables and lines. Things.
Contrary to China, Japan has a lot of overhead wires. Whether it is from anime or Japanese dramas, we can observe that the streets and cities of Japan are densely covered with lines, which looks extremely untidy, but Japan has to choose this as a last resort. Because of the frequent occurrence of earthquakes in Japan, underground cable lines are extremely vulnerable to damage, and the maintenance cycle will be very long, so that overhead lines in Japan are more affordable and convenient. The interference of trees along the route can also beautify the city and avoid the risk of electric shock for urban people.
After understanding the concept of Quadruplex Aerial Bundled Cable lines, let's talk about the operation precautions of cable lines. First, do not run the line under load for a long time, because this will cause abnormal temperature of the line, which will damage the line and reduce the service life of the line. Secondly, the cable line feeder protection should not be used for reclosing. After the feeder of the cable line is tripped, do not ignore the inspection of the cable, and it should be noted that) the cable line must be re-tested before it can be put into use when it resumes operation after being out of service.
In line maintenance, the main task is to do a good job in three aspects: load monitoring, cable metal sheath corrosion monitoring and insulation monitoring, to keep the cable equipment always in good condition and prevent sudden cable accidents.
