Designing an overhead distribution line is a multifaceted process that involves balancing several critical factors to ensure optimal performance and safety. The primary factors include:

• Electrical Parameters: The design must account for the line's voltage level, current-carrying capacity (ampacity), and expected power losses. The conductor size and material (e.g., ACSR, AAAC) are selected based on these electrical requirements.

• Mechanical Parameters: This involves calculating the forces on the line and its supporting structures. Key mechanical considerations include the sag and tension of the conductors, the strength of the poles, and the effect of external loads from wind and ice.

• Environmental and Geographical Factors: The design must be adapted to the specific conditions of the project location. This includes the topography of the land, local weather patterns, and soil conditions, which all impact the selection of pole types and foundation design.

• Safety and Regulations: The design must adhere to strict national and international electrical safety codes. This includes maintaining the required clearance distances to the ground, buildings, and other infrastructure to prevent accidents.
