utility pole is a column or post usually made out of wood used to support overhead power lines and various other public utilities, such as electrical cable, fiber optic cable, and related equipment such as transformers street lights. 01 WHAT IS A UTILITY POLE? Utility poles form the backbone of electrical infrastructure in the U.S. These mid-19th century inventions originally carried telegraph lines but were later adapted to support overhead power distribution lines as an overwhelming demand for electricity swept through the nation. Most utility poles operate as joint poles. What's on an Electric Power Pole? This is an illustration of basic equipment found on a typical distribution pole and can vary by location. Insulators prevent energized wires from coming in contact with each other or the utility pole. A crossarm holds the wires up on the pole. Residential utility pole diagrams are essential for understanding the infrastructure that provides electricity, telephone, and internet services to homes. These diagrams provide a visual representation of the connections and components that make up the utility pole, such as transformers, meters, and cables.

Most utility poles are known in the jargon of the business as "joint poles," because they carry the hardware of two or more companies. Vertical zones on joint poles are dedicated to various power distribution, cable and telephone service uses, usually in descending order. • Trenches for multiple utility apparatus must be installed to provide the correct depth of cover in line with the current version of the SWUK Guidelines on Positioning and Colour Coding of Underground Utilities Apparatus. The diagram below shows the depths of cover and dimensions for each utility. Electric Mains Cables - Open Trench

Basics of Overhead Line Safety OSHA provides the following safety tips concerning overhead lines and equipment: Electrical hazards can cause burns, shocks and electrocution (death). Assume that all overhead wires are energized at lethal voltages. Never assume that a wire is safe to touch even if it is down or appears to be insulated. A power pole is a post used to support overhead power lines and public utilities, such as power lines and related equipment such as transformers.
