Advantages of the use of underground cables

Underground power cables are cables used to transmit and distribute electrical energy. Power cables are often used in urban underground power grids, power station outgoing lines, internal power supply of industrial and mining enterprises, and underwater transmission lines across the river and sea. In power lines, the proportion of cables is gradually increasing.

Power cable lines are generally laid underground or underwater, and there are also power cable lines laid overhead. Power cable lines are mainly composed of cables, cable intermediate joints, cable terminal heads, etc. Some power cable lines also have accessories, such as pressure tanks, pressure and temperature warning devices, etc. Underground power cable lines also include corresponding civil construction facilities, such as cable trenches, pipes, shafts, tunnels, etc.

2. Maintenance workload is small and frequent inspections are not required;

3. No need to erect towers;

4. Helps improve the power factor.
