Transmission Line: Definition and Importance

Transmission Line: Definition and Importance


A transmission line is a set of conductors used to transport electrical power from one place to another. It is an essential component of the electrical power system that plays a vital role in delivering electricity to homes, businesses, and industries.

 

The primary function of a transmission line is to transfer electrical power at high voltage over long distances with minimum power loss. The reason for transmitting power at high voltage is to minimize the energy loss that occurs due to resistance in the conductors. This is achieved through the use of transformers that step up the voltage to very high levels, typically in the range of 110 kV to 765 kV, for long-distance transmission.

 

Transmission lines are typically made of either aluminum or copper conductors that are suspended from high towers using insulators. The towers are spaced at regular intervals to support the weight of the conductors and maintain the required distance between the conductors and the ground or other objects. The spacing between the conductors is critical to prevent electrical arcing and ensure safe operation.

 

Transmission lines can be either overhead or underground. Overhead transmission lines are the most common type of transmission line and are used to transport power over long distances. Underground transmission lines are used in urban areas and other sensitive locations where the aesthetic and environmental impact.

World's tallest power transmission towers

World's tallest power transmission towers

The world's second tallest power transmission towers, built by Haldia Energy Limited (HEL), has come up in West Bengal.

The 236-metre-long twin towers, located at HEL's 600-MW capacity plant at Haldia and Raichak across the river Hooghly, are the tallest in the country.
The 236-metre-long twin towers, located at HEL's 600-MW capacity plant at Haldia and Raichak across the river Hooghly, are the tallest in the country.

Covering a span of 1.5 km, the twin towers weigh 1,800 tonnes.

"The power evacuation network is the most sophisticated one. The twin towers are the second tallest ones in the world and the tallest in India. It is something we are very proud of," Sanjiv Goenka, chairman of the RP-Sanjiv Goenka Group, told reporters here today.

HEL is a wholly-owned subsidiary of CESC Limited


Generation of power would begin from next month in the plant.

The tallest power transmission towers in India till date were located at Rihand lake in Uttar Pradesh with a height of 185 metres.

Company officials said the towers are designed by Elias Ghannoum, an international expert on designing transmission lines.

The 400 KV twin circuit twin moose transmission line is specially designed to withstand wind force on the conductors as well, as these are in a high wind zone.

The world's highest transmission tower (370 metres) is located at Mount Damaoshan in China.
