Introduction to Overhead Cable
Overhead cables are an essential part of the electrical power distribution and communication infrastructure. They are designed to be suspended above the ground, typically supported by poles or towers. These cables are used to transmit electricity over long – distances, from power generation plants to substations and then to consumers. In the field of communication, overhead cables are used for telephone lines, cable TV, and broadband internet connections. Overhead cables offer several advantages, such as relatively low installation costs compared to underground cables, easy maintenance, and the ability to be easily inspected for damage. However, they are also more vulnerable to environmental factors like storms, lightning, and extreme temperatures. Overhead Cable
