Power poles are pole-shaped or lattice structures that support overhead power transmission lines and overhead ground wires, maintaining a specific distance between them and the ground. Lattice structures are the most commonly used and are the primary structures for ultra-high voltage power lines. They can be categorized as self-supporting towers and guyed towers, with grounding methods including horizontal extension grounding and deep-buried grounding electrodes.

Based on their functions and positions in the power lines, there are six structural types: straight poles (also known as intermediate poles), tension poles (also known as load-bearing poles), angle poles, terminal poles, crossing poles, and branching poles. The pole tower structure is a hyperstatic structure, subjected to loads such as wind, ice and snow, seismic, and conductor self-weight loads, all of which are dynamic loads that vary over time.
