Pylons of Cádiz

The crossing consists of 16 pylons: two suspension pylons, both 158 metres (518 feet) tall, that carry the line over the Bay of Cádiz,[1] two strainer portals built of concrete, and at each strainer portal a group of 6 monopolar strainers, which are used to carry the conductors from the strainer portal to the first standard line tower (at the northern end of the span) respectively to the switchyard of Cádiz Substation (at the southern end of the span).

The powerline crossing does not use a ground conductor in the span section despite its great height.

Each tower is a hollow mast resembling a truncated cone (or frustum).

The construction was carried out under the supervision and direction of Remo Scalla, a close friend of Toscano.

The same team of Toscano, the designer, and Scalla, the builder, also joined forces in building the Pylons of Messina which support the lines that span the Strait of Messina, between Calabria, on the mainland of Italy, and the island of Sicily.
