Depending on requirements and the available resources utility poles vary in both size and the material used to make them. An average pole is around 12 metres 40ft in height, and depending on the terrain spaced anywhere between 38 — 91 metres ft apart.
The utility poles used to accommodate overhead lines can be divided by two main criteria: a pole material; and b transmission type. The most common three materials used to make utility poles are wood, concrete, and steel.
In selecting the best material a range of factors need to be considered, including the location, voltage load, and installation and maintenance costs.
Cheap and widely available, wood has historically been a popular choice for line poles, with pine, cedar, and fir varieties especially favoured due to their height and durability.
Wooden poles also need to be treated with a preservative to minimise the risk of fungi, rot, and the damage caused by wildlife.
In modern times there has been a shift away from creosote towards the use of more environmentally-friendly preservatives, such as Pentachlorophenol and Copper Zinc Arsenate.
Poles crafted from wood have a limited voltage capacity and run a fire risk if exposed to extreme heat. In addition, they require regular maintenance to ensure that they are not rotting or otherwise deteriorating e.
Seasoned wooden utility poles have an average lifespan of years. Their eventual deterioration usually results from rot below ground level. As a more durable, environmentally-friendly option with a higher loading capacity, steel is often used as an alternative to wood. Because it can be melted down and reformed, steel also offers flexibility with pole length — enabling taller poles suited to higher voltage loads to be made. Poles crafted from steel are also relatively reliable and easy to install — making them the ideal choice in densely populated towns and cities.
For the heavier duty projects covering a wider area, large steel towers are used in place of poles. Steel electricity towers can transport anywhere up to , volts. However, steel poles are more expensive to manufacture and can be prone to rust.
As there is also a risk of electrocution if a live wire comes into contact with the pole, more robust safety features are necessary for their use.
