Pipes
They are conduits made up of several triple-shaped tubes, designed to house large insulated cables with voltages greater than 1,000 volts. These conduits, which allow avoiding the visual impact of overhead lines, include large underground infrastructures for housing the splices of the cable sections every 700 or 800 meters.
Electrical substations
They are enclosures that include buildings, structures and foundations that house high voltage transformers. They are intended to modify and establish the voltage of high voltage power lines.
