Advantages

1. Low installation cost: The installation cost of overhead lines is relatively low and the construction is convenient. Compared with underground cables, overhead lines do not require large-scale earthwork and pipeline laying, saving construction costs and time.

2. Good heat dissipation performance: Overhead lines are exposed to the air, have good heat dissipation performance, and can withstand large current loads. This gives overhead lines certain advantages in transmitting high-power electrical energy.

3. Easy maintenance and overhaul: The structure of overhead lines is simple, which is easy to maintain and overhaul. Fault troubleshooting is easy and the maintenance cost is low. When performing maintenance and overhaul on overhead lines, there is no need to dig the ground, which reduces the impact on traffic and the environment.

4. Strong adaptability: Overhead lines can cross terrain obstacles such as mountains and rivers and have strong adaptability. In some areas with complex terrain, overhead lines are the only option for power transmission.

Scope of Application

1. Rural areas: Overhead lines are widely used in rural areas. Overhead lines can provide reliable power supply for residents and agricultural production in rural areas.

2. Mountainous areas: In mountainous areas, the terrain is complex, transportation is inconvenient, and it is difficult to lay cables underground. Overhead lines can cross terrain obstacles such as mountains and rivers to provide electricity supply to residents and businesses in mountainous areas.

3. Long-distance power transmission: Overhead lines are suitable for long-distance power transmission, especially when transmitting high-power electricity. Overhead lines have good heat dissipation performance and can withstand large current loads, which can meet the needs of long-distance power transmission.
