Wood poles are classified by which of the following criteria?

The classification of wood poles is primarily based on several key criteria, one of which includes height. This categorization helps in determining the appropriate type of pole for specific applications, such as transmission or distribution lines. Height is significant because it influences factors such as load capacity, strength, and the pole’s ability to reach necessary clearance levels for safety and functionality.

While type of wood, preservative treatment, and presence of knots also play important roles in defining the quality and suitability of wood poles, they do not encapsulate the primary classification system. Type of wood affects durability and load-bearing characteristics, preservative treatment helps to protect against decay and pests, and the presence of knots may impact the strength and reliability of the pole. However, for the primary classification, height serves as a more straightforward and critical measure in the industry.
