Overhead cables and underground cables are common methods of power transmission. They differ significantly in terms of installation methods, use environments, and technical characteristics.
Overhead cables and underground cables are common methods of power transmission. They differ significantly in terms of installation methods, use environments, and technical characteristics.
Overhead cables refer to the transmission method in which cables such as power lines and communication lines are installed on supports such as power towers and poles. Underground cables refer to the transmission method in which cables are buried underground. The different installation methods of these two methods lead to different characteristics and applicable scenarios.
Overhead cables are simple and convenient to install, and do not require large-scale civil engineering projects. Therefore, they are more common in areas with more ample land conditions. It has the advantages of low installation and maintenance costs, and easy fault detection and repair. However, overhead cables are susceptible to weather factors and the risk of being damaged by external forces.
In contrast, underground cables are complex to install, costly, and require a large amount of civil engineering projects. But they are beautiful, reliable, and pose no threat to the surrounding environment and personnel safety. Underground cables can effectively prevent damage by external forces and are not restricted by weather factors. They are suitable for cities, residential areas, and other places. In addition, underground cables can also reduce electromagnetic radiation and reduce interference with the surrounding environment.
In addition, overhead cables are more prone to failure than underground cables. The maintenance of overhead cables requires regular inspections to ensure their normal operation. However, underground cables are difficult to troubleshoot and repair after failures because they are underground.
In summary, there are obvious differences between overhead cables and underground cables in terms of installation methods, use environments, characteristics, and applicable scenarios. Choosing a suitable cable transmission method requires considering specific environmental requirements and economic costs. Regardless of which method is chosen, effective maintenance and management are required to ensure the normal transmission and supply of electricity.
