What is the primary function of an electrical overhead line?

2025-08-13

The primary function of an electrical overhead line is to efficiently transmit and distribute electrical energy from power generation plants to substations and, ultimately, to end-users like homes and businesses. These lines act as the "highways" of the electrical grid, moving large volumes of power over long distances at high voltages.


The function of an overhead line can be divided into two main categories:

  1. Transmission: Large-scale, long-distance transport of high-voltage electricity from a power plant to major substations.

  2. Distribution: The local, shorter-distance delivery of lower-voltage electricity from a substation to consumers.

Overhead lines are generally the most cost-effective method for this purpose because the air serves as a natural insulator, reducing material costs. We provide the essential OHTL wire cable conductor tension stringing equipment to build and maintain both types of lines, ensuring they function reliably.
