Hello, I am looking for someone to write an article on Construction and Maintenance of Transmission Lines. It needs to be at least 2500 words. Lastly, the discussion will use a case study involving an actual accident case involving transmission towers and overhead cables. The case study will be essential in relating the information outlined in the earlier sections of the paper especially in relation to the Health, Safety, and Environment.
A transmission tower is typically a structure that is used to support overhead power cables. The tower can also be referred to as a hydro tower or electricity pylon depending on the functions served and the location. Transmission towers are used largely where high voltage AC and DC systems are involved and usually, they are often available in varying sizes and shapes. The towers are typically tall with heights ranging up to 55 meters. Transmission towers are mostly constructed using steel although other materials such as concrete and wood are used in various parts of the world (Saravanan, 2012).
Overhead power cables, on the other hand, are structures used in distributing electrical energy along long distances over the land. The cables are usually supported by the transmission towers described above or in some cases, by poles. Overhead power lines are very popular for the transmission of electricity in most parts of the world primarily due to their economic nature as compared to the underground cables. This is largely attributed to the lesser insulation required in overhead power cables since most of it (insulation) is provided by air. In most cases of use of overhead power cables, aluminum is the material used to make them although they can also be reinforced using other materials such as carbon, steel and glass fiber. The choice of materials used to make overhead power cables largely depends on the amount of voltage the cables are expected to carry and the distance of transmission. Overhead power cables are classified into five main categories depending on the amount of voltage that they carry. low voltage, medium voltage, high voltage, extra-high voltage and ultra-high voltage cables.
