Operation And Maintenance of Photovoltaic Cables To Pay Attention To What

Recently, I learned that the normal operation of photovoltaic cables and the overall power production operations are closely related, because the normal operation of the cable line is directly related to the production safety of enterprises and the safety of employees' lives. Therefore, it is important to understand the operation and maintenance of power lines and wiring problems when they occur.

In the power industry, the so-called cable line actually refers to the line used to transmit electrical energy through the cable. It usually consists of cables, cable glands and wire ends, and it also includes laying related projects such as cable trenches, pipes and shafts, and tunnels, etc. Depending on the construction requirements of different geographical environments, the cable line will be adapted to local conditions.

Cable lines have many advantages over overhead lines.

One of them is that they are not affected by natural disasters, such as heavy rain and snow and hail, and cable lines can better isolate these factors, and the second advantage is that they make the city look neater, and the construction of cable lines is not disturbed by city trees and beautifies the city, avoiding the risk of electric shock to the city residents.

In contrast to China, Japan has many overhead power lines. Whether in anime or Japanese theater, we can see that Japanese streets and cities are covered with dense lines that look very messy, but Japan had to choose this as a last resort. Because Japan is prone to earthquakes, underground cable lines are highly susceptible to damage, and maintenance cycles are long, so overhead lines in Japan are cheaper and relatively more convenient.

After understanding the concept of laying photovoltaic cable lines, let's talk about the operating precautions for cable lines. First, do not overload the lines for a long time, as this can lead to temperature anomalies that can damage the lines and shorten their service life. Second, the cable feeder protection device should not be used for reclosing. After the cable feeder has tripped, please do not neglect to check the cable, and it is worth noting that the cable must be retested before it can be used again after it has stopped and resumed operation. In the whole process of PV cable line maintenance, the main task is to do a good job in three areas: load monitoring, cable metal sheath corrosion monitoring and insulation monitoring, in order to keep the cable equipment in good condition and prevent sudden cable accidents.

Well, the above is about the "operation and maintenance of photovoltaic cables to pay attention to what" is introduced, I hope it can help you! We recommend to continue to pay attention to XSD Cable, to learn more information.
