This ultimate guide on Power transmission and distribution provides all fundamental information you need to understand about Electric power transmission and distribution.
Electric Power Transmission and distribution refers to the stage of carrying electric power over poles and wires from power stations to homes or industries.
After the generation of electricity, a system of electrical wires carries the electricity from the power stations to our homes. Transmission and distribution lines are two responsible for carrying the generated power from plants to our homes.
Methods of Electric Power Transmission and Distribution
Electric power can be transmitted either by overhead transmission lines or by underground lines. Overhead transmission lines are employed for transmission purposes while underground transmission lines are preferred inside urban areas where look and public safety.
Components of Overhead Transmission Lines
Conductors are the wires which carry electric power from the sending end power station to the receiving end
station. Power lines employ different types of conductors of which the ACSR is most popular type of insulator.

On the basis of length, the transmission lines are classified into three types: short, medium, and long.
Pole or Pylon
It is the main structure that is responsible for carrying transmission lines conductors. They are responsible for keeping the conductors at a suitable level above the ground.
If conductors were directed connected to pylon they were shorted all together. Rather insulators are attached to transmission lines and then conductors from the ground. Learn about different types of insulators.
Different between HVAC and HVDC Transmission/Distribution
Electric power can either be transmitted by employing AC or DC. As name indicates HVDC uses direct current for the bulk transmission of electrical power while HVAC system uses Alternating current for power transmission purposes.
