The advantages of blank lines are mainly reflected in the following aspects:
Improving transmission efficiency: The span of overhead lines is relatively large, and the distance between wires is relatively stable, which will not affect each other due to weather or environmental differences. Moreover, due to the high height of overhead lines, they will not be affected by land cover, resulting in higher power transmission efficiency.
Relieve line load: The span of overhead lines is relatively large and the distance between them is far, which can alleviate the load pressure borne by the lines to a certain extent. Meanwhile, overhead power lines have the advantage of air cooling, which can save costs and reduce usage pressure.
Reduce safety risks: Overhead power lines do not come into contact with the ground or buildings, and their strength and safety can be effectively guaranteed, making it safer for people to walk and stay near overhead power lines.
Easy to maintain: Overhead power lines are exposed to the air, and defects can be detected in a timely manner through regular patrols. When there are faults, they are easy to repair and maintain.
Convenient construction: The construction period of overhead power lines is short, the construction is convenient, and it is easy to detect faults and facilitate maintenance.
Multi circuit co pole installation: Overhead lines can support multi circuit co pole installation, improving the utilization rate of the lines.
