Power Line Industry

The electric power industry provides the production and delivery of electric energy, often known as power, or electricity, in sufficient quantities to areas that need electricity through a grid connection. The grid distributes electrical energy to customers. Electric power is generated by central power stations or by distributed generation.
Many households and businesses need access to electricity, especially in developed nations, the demand being scarcer in developing nations. Demand for electricity is derived from the requirement for electricity in order to operate domestic appliances, office equipment, industrial machinery and provide sufficient energy for both domestic and commercial lighting, heating, cooking and industrial processes.
This industry is filled with hard working men called lineman. Linemen are known for the long hours they work and the sometimes tough conditions they work in. These men are often a very close nit group because they all know the dangers the job entails and the risks that the job comes with. Safety is the absolute number one priority in the job and must never be overlooked in the job. The lineman is a certain breed of man, and they are known for their selfless work ethic and are a respected group of people.

Overhead Construction

Electricity distribution is the final stage in the delivery of electricity to end users. A distribution system's network carries electricity from the transmission system and delivers it to consumers. Typically, the network would include medium-voltage (1kV to 72.5kV) power lines, substations and pole-mounted transformers, low-voltage (less than 1 kV) distribution wiring and sometimes meters. Conductors for distribution may be carried on overhead pole lines, or in densely-populated areas where they are buried underground. Urban and suburban distribution is done with three-phase systems to serve both residential, commercial, and industrial customers. Distribution in rural areas may be only single-phase if it is not economical to install three-phase power for relatively few and small customers. Building overhead lines takes several steps before the task is complete. You must first set your pole, and then frame whatever structure is needed for the specific job. Then you sag in your line, and then tie in you conductor. Then you are ready for…
