Top 12 Longest Transmission Lines In The World

Transmission lines are mostly of AC transmission but they are limited to certain distances so for the long distances the HVDC (High Voltage Direct Current) transmission is used because of fewer components and fewer losses. The longest transmission lines in the world are mostly HVDC technology. The bulk power transmission is easily possible with the HVDC transmission. Below are the longest transmission lines in the world.

12. COLLASAL DC LINE- UNITED STATES OF AMERICA

The Collasal DC line is the longest over head transmission line in the United States. This Transmission line runs between the Celilo near Dellas to Sylmar converter station in Los Angeles. The length of this transmission line is 1361 KM. The Voltage transmitted through this line is approximately 400KV.

11. CAHORA BASSA (SONGO-APOLLO) TRANSMISSION LINK- SOUTH AFRICA
