Utility Poles, also known as transmission poles, support overhead power lines and various other public utilities, such as cable, fibre optic cable, and related equipment such as transformers and street lights. 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.
Electrical cable is routed overhead on utility poles as an inexpensive way to keep it insulated from the ground and out of the way of people and vehicles. Utility poles can be made of wood, metal, concrete, or composites like fiberglass. They are used for two different types of power lines; subtransmission lines which carry higher voltage power between substations, and distribution lines which distribute lower voltage power to customers.
Utility poles were first used in the mid-19th century with telegraph systems, starting with Samuel Morse who attempted to bury a line between Baltimore and Washington, D.C., but moved it aboveground when this system proved faulty. Today, underground distribution lines are increasingly used as an alternative to utility poles in residential neighborhoods, due to poles' perceived ugliness.

All timber utility poles, need to be treated using a creosote or CCA process in order for them to be protected from pest, insects and fungi infestations. Timber that is in contact with the ground such as the utility pole itself, will need to be H4 treated, while the cross arms will require a H3 treatment. The lesser treatment is due to there being no ground contact.
