Electricity as most of us know, are conveniently utilized as we plug our appliances and machines to our power sockets. However, the origin of that very electricity though may actually be as far as hundred and even thousand of kilometers away. These are from power plants and other power generating stations.
A generating plant will be useless unless its generated energy (power) in millions and even thousands of billions of watts will be delivered to its consumers, to us. These electrons traveled in speed approaching that of light, through a medium called transmission and distribution lines.
Electricity might be transmitted and distributed in either on the following ways(click on link for pics):
The choice and selection of methods of construction would usually vary on the philosophy of the personalities and circumstances involved. These would refer to the owner of the lines, the engineering team and the culture, practice and applicability wherein the transmission lines are located.
The most common type of transmission and distribution lines there is, are the overhead types. These are conductors, bare and insulated those are attached to supporting structures, usually poles and towers. It could be attributed to the fact that it would be cheaper in first cost, maintenance and repair as compared to that of underground.
The main selling point of an underground system is in its aesthetics. Certain customers or situation would require a use of underground cables in distributing power. Common cases would be the impracticality of putting overhead lines due to existing aerial obstruction. Submarine cables are common in inter-island grid interconnection.
