What Are Overhead Power Lines Made Of​

Overhead power lines comprise a complex assembly of components designed to safely and efficiently transmit electrical energy.

Key elements include conductors, typically aluminium conductors steel-reinforced (ACSR) for strength and conductivity; insulators, providing electrical isolation from supporting structures; hardware, encompassing clamps, connectors and suspension systems ensuring mechanical integrity and reliable current flow.

The specific configuration and materials employed vary according to voltage levels, environmental conditions, and transmission distance.  Careful selection and installation of each component are crucial for maintaining system reliability and operational safety.
