![]() ![]() Utility poles were first used in the mid-19th century in America with telegraph systems, starting with Samuel Morse, who attempted to bury a line between Baltimore and Washington, D.C., but moved it above ground when this system proved faulty. The first poles were used in 1843 by telegraph pioneer William Fothergill Cooke, who used them on a line along the Great Western Railway. ![]() They are used for two different types of power lines: sub transmission lines, which carry higher voltage power between substations, and distribution lines, which distribute lower voltage power to customers. ![]() Utility poles can be made of wood, metal, concrete, or composites like fiberglass. A Stobie pole is a multi-purpose pole made of two steel joists held apart by a slab of concrete in the middle, generally found in South Australia.Įlectrical wires and cables are routed overhead on utility poles as an inexpensive way to keep them insulated from the ground and out of the way of people and vehicles. It can be referred to as a transmission pole, telephone pole, telecommunication pole, power pole, hydro pole, telegraph pole, or telegraph post, depending on its application. A pair of shoes can be seen hanging from the wires (center-left, far right)Ī 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 and street lights. We encourage members to check their property for potential livestock and guy-wire interactions.Post used by public utilities to support overhead wires and related equipment Utility pole supporting wires for electrical power distribution, coaxial cable for cable television, and telephone cable. For example, cattle rubbing on a guy-wire will cause a utility pole to shake and move, decreasing the stability of the pole which could result in a power outage.īattle River Power Coop members who have cattle pastured or corralled where a guy-wire is present can improve the reliability of their own electricity and the safety of their herd, by installing a fence post on either side of the guy wire. We are now issuing another caution about guy-wires relating to livestock. Annually, we remind farmers during seeding and harvest to check your surroundings all day/every day and be certain that they can safely navigate around the power poles, power lines, or guy wires.Īdditionally, we have cautioned members who are snowmobilers in rural areas to watch out for guy-wires, as snow depth and weather conditions (in particular snow glare on a sunny day) can compromise the visibility of these guy-wires. However, not all free-standing poles or structures may have reflectors. The lower end where the cable enters the ground is often encased in a length of yellow or orange plastic reflector to make it more visible so that people or vehicles do not run into it. Some utility poles buried in the ground have sufficient strength to stand on their own, but others need guy-wires to support loads and to resist ground movement. Distribution System Operator Services (DSO)Ī guy-wire, guy-line, or guy-rope, also known as simply a guy, is a tensioned cable designed to add stability to a free-standing structure.Electric Utilities Act Code of Conduct Regulation Compliance Plan. ![]()
