With the development of the times, some things are sufficient to be displayed on the ground alone, and sometimes it can also affect the appearance of the city. Therefore, manufacturers have started to rely on underground transportation. There are subways installed underground, underground drainage channels, and inspections. Below, we will reveal the advantages of placing cables underground.
1. Can enhance the reliability of urban power grids
Exposed metal wires in cities are easily corroded by acidic, alkaline gases, and water vapor in the atmosphere, posing significant risks to overhead lines. Therefore, it is very necessary and particularly important to use overhead lines to enter the ground in cities. Underground cables can completely bring reliability and higher safety to the city's power supply.
2. Can enhance the transmission capacity of urban lines
Usually, overhead transmission lines transmit electricity in one direction using two towers, with only 2 to 4 overhead transmission lines. The cable lines buried underground can reach up to 20 circuits. Furthermore, underground ultra-high voltage cables generally have more efficient copper conductors, allowing them to efficiently transmit electricity to end users, greatly reducing power transmission losses.
3. Can eradicate visual pollution and beautify urban environment
The massive and spider web covered urban overhead lines have greatly damaged the urban landscape, disrupted the traditional and modern building facades, and caused serious visual pollution. By placing overhead lines on the ground, the urban road space can be restored to a pure state, creating a comfortable and beautiful visual experience for people, and allowing the city to immerse itself in beauty for a pleasant experience.
4. Can enhance the utilization value of urban land
Land is a valuable but scarce resource, especially in the central areas of modern cities. Due to the higher spatial safety distance requirements of overhead lines compared to underground pipelines, there are more restrictions on the use of adjacent land, which greatly reduces the utilization value of land. Changing to underground cable lines can improve the utilization value of land.
