The height range of the majority of distribution poles typically falls between 35 to 55 feet. This height range is optimal for effectively carrying the overhead electrical distribution lines that supply power to residential and commercial areas. At this height, the poles can maintain adequate clearance from the ground and ensure safety from potential hazards, such as vehicles and trees, while also allowing for effective distribution of electric power over varying distances.

Distribution poles are designed to provide enough strength and stability to support the equipment and lines attached to them, as well as to withstand environmental conditions such as wind and ice loads. Poles lower than this range may not be sufficient to achieve the necessary height for electrical safety clearances, while poles much higher than this range are typically associated with transmission lines rather than distribution networks. Therefore, the chosen range of 35 to 55 feet aligns well with industry standards for distribution infrastructure.
