Introduction to Overhead Cable
Overhead cables are an essential part of the power transmission and distribution infrastructure. They are used to carry electrical energy over long distances, from power generation plants to substations and ultimately to consumers. These cables are suspended on poles or towers, which makes them a cost - effective solution compared to underground cables, especially in rural and suburban areas. Overhead cables are designed to withstand various environmental conditions, including extreme temperatures, high winds, and heavy snowfall. They are typically made of materials such as aluminum, copper, or a combination of both, and may be insulated or bare, depending on the application.
