Power cables are often used in urban underground power grids, power station outgoing lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across the river.
The Main Advantage
1. Occupies less land. Generally buried in the soil or indoors, in trenches, tunnels, the insulation distance between the lines is small, no poles are used, and it occupies a small area and basically does not take up space on the ground.
2. High reliability. Affected by climatic conditions and surrounding environment, stable transmission performance and high reliability.
3. It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and superconducting power cables.
4. The distributed capacitance is large.
5. Less maintenance workload.
6. The possibility of electric shock is small.
