Structure

Structure is an abstract class whose attributes are inherited by features that support electrical transmission and distribution equipment. Structures can be located overhead, on ground surface, or underground.

Overhead structures are designed to support mechanical loads imposed by conductors and equipment as well as additional loads presented by wind, ice, and/or snow. ANSI-provided specifications and dimensions rate poles, which are grouped into classes based on their circumference six feet from the butt. Poles of a certain class and length are designed to have about the same load-carrying capacity.

Overhead structures, such as poles, H-frames, and towers, vary in material, height, and guying and/or bracing requirements based on the combination of anticipated vertical and horizontal loads. Surface structures house equipment on the ground including pedestals, enclosures, and pads.
