It consists of one or more uninsulated electrical cables commonly multiples of three for three phase power suspended by towers or poles.
Wood pole power line.
They are the backbone of overhead line construction and most of these poles are pressure treated with some type of preservative.
These are made of seasoned wood sal or chir and are suitable for lines of the moderate x sectional area and of relatively shorter spans say upto 50 metres.
The many possible uses include barn poles power line poles playground structures golf course netting and light poles.
Such supports are cheap easily available provide insulating properties and therefore are widely used for distribution purposes in rural areas as an economic proposition.
A utility pole is a column or post 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 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.
Also failures in underground lines can take significantly more time to identify and repair compared to overhead line repairs.
Choosing a pole treated with an appropriate wood preservative for the environment can save a utility time frustration and money.
Since most of the insulation is provided by the surrounding air overhead power lines are generally the least.
An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances.
