Conductors: materials that serve as a means of transporting energy, from the beginning to the end of the line. They offer little resistance to the flow of energy so that it can circulate without difficulty. In a transmission line, the number of conductors will depend on the number of circuits per phase. Copper is typically used, though over time it has been replaced, given its lightness and the same resistance capacity.
Support structures: these are usually reticular structures that support the overhead lines and cables of an electrical transmission line.
Insulators: these elements mechanically fasten the conductors, keeping them isolated from each other and the ground.
Ground wires: these are used in high voltage lines to protect the rest of the conductors against possible atmospheric incidents, such as lightning strikes.
