The Transmission line and Distribution line both are used to carry power or electricity from one place to the other. The difference between transmission and distribution line are explained on the basis of the factors like the basic usage of the transmission and distribution line, their working supply phase, voltage level and level of conduction.
The Difference Between Transmission and Distribution Line is given below in the tabulated form.
|BASIS||TRANSMISSION LINE||DISTRIBUTION LINE|
|Usage||Transmission Line helps in the movement of electricity from power plant to the substations.||The Distribution line carries electricity from the substation to the consumer’s end.|
|Phase||It is carried out electricity in three phase supply system.||It requires a single phase supply system for carrying electricity.|
|Voltage level||Carries electricity at a very high voltage. About 11000 volts.||Carries electricity at a very low and safe level of about 220 volts.|
|Current conduction level||They conduct current at 69 kV or more.||They conduct less than 69 kV|
|Thickness||Transmission lines are thick lines.||Distribution line are thin as compared to the transmission line.|
Generation of electricity is a major factor, but how this electricity is transmitted from the power stations to the substations and finally to the consumers is also important. This process is done by transmission and distribution lines.
Transmission lines are a high voltage line that carries electricity from power plant to the substation from it is further distributed to various areas for different purposes. Distribution lines are low voltage lines that carry electricity from the substations to the end users for residential and commercial use.
The Difference Between Transmission and Distribution Line
- Transmission Line helps in the movement of electricity from a power plant or power station to the various substations whereas the distribution line carries electricity from the substation to the consumer’s end. i.e, to the residential and commercial customers.
- Transmission line carries power or electricity in three phase supply system. Distribution system requires a single phase supply system for carrying electricity.
- Transmission line carries electricity at a very high voltage that is of about 11000 volts whereas Distribution lines carries electricity at a very low and safe value level that is about 220 volts.
- Transmission line, conducts current at 69 kilo volts or more, but distribution line conduct current at less than 69 kilo Volt.
- Distribution line are thin as compared to the transmission line.
In this way, transmission line is different from distribution line.

Very interesting post, thank you! What is the difference between the voltage level and the current conduction level, and why are both measured in volts? Thanks!
very well explained!
