Electricity is considered as one of the most important components necessary for leading a comfortable and happy life. It is the main source of energy for running a wide range of tools, machines, appliances and equipments which are used for various purposes such as manufacturing products on a large scale, creating comfortable living conditions and making food items. Electricity is mainly produced in large quantities at power plants. However, one of the major problems faced by people was the transfer of the energy produced at power plants to the areas where it was necessary. This called for the need of electrical transmission lines for transmitting electricity to different places such as homes, offices, construction sites, etc.
Transmission lines are of the most common ways of transferring electrical energy over long distances. Transmitting electricity is not an easy task at all. Utmost care should be taken while installing the lines and connections in order to prevent electrical hazards which are extremely dangerous. The condition and quality of the transmission line hardware should also be inspected properly before using them for the desired purpose. Bulk amounts of electrical energy are transferred from the power plants generating electricity to the electrical substations which are situated in close proximity to the demand centers. These lines are extremely different from the wires that are used locally for transmitting electricity from the high voltage electrical substances to the customers. Transmission networks are formed by interconnecting different kinds of lines.
Over head transmission lines are one of the most commonly used ways of transmitting electricity conveniently over large distances. Overhead power lines are structures utilized for transmitting and distributing electricity across large distances. They are manufactured using a number of conductors which are supported by utility poles or towers. Over head transmission lines are considered as one of the cheapest modes of transmitting large quantities of power because a large portion of the insulation requirements are provided through the air. The towers or poles used for sustaining these lines are usually manufactured from wood, steel, aluminium, concrete or reinforced plastics. While aluminium is mainly used for manufacturing the exposed wire conductor
