<p>The structure for carrying power cables consists of a base-section (10) which is anchored to a concrete plinth (11), this section comprising hollow tubes (12) joined together to form the four sides of a square-based pyramid. At the bottom of the base section is a bedplate (14) which houses the foot of two hollow masts (15,16) which slope away from each other. These masts have, on their upper part, supports (15A,16A) to which the power cables (20,21) are attached. Guys are fastened to the masts to make them more stable.</p> |
