Advantages of ACSR in overhead transmission lines

ACSR is widely used in overhead transmission and distribution lines. ACSR has simple structure, easy to set up and maintain, low-cost lines, large transmission capacity, and is also conducive to special geographical conditions such as crossing rivers and valleys. It has very good conductivity, sufficient mechanical strength, tensile strength, and the distance between towers can be enlarged.

1. ACSR has good corrosion resistance and thermal stability. The long-term operating temperature is as high as 250 ° C without reducing its mechanical strength Under high temperature working conditions, its gallop has no obvious change. Moreover, it also has sub damping characteristics, which helps to reduce aeolian vibration and line loss of transmission lines.

2. The diameter of ACSR is small. Smaller diameter and smoother outer surface can reduce the aerodynamic coefficient Reduce the harm of breeze vibration and dancing. In turn, the conductor can reduce icing and wind load, have a larger aluminum cross-sectional area, improve the current carrying capacity and reduce line loss. In addition, the smoother outer surface of the conductor can also reduce the level of corona and radio interference.
