Abstract
The ducting has a U-section duct (2) with a cover (9). At least one side (3) of the duct has a series of holes formed in it. These holes are arranged in several series forming lines along the duct and columns along its depth. Each line of perforations is identified by a distinctive line and each successive column by a sign, a figure for example. The ends of the duct are adapted to connect with similar ducts. The internal faces of the duct and cover are metal coated, so that the interior volume constitutes a Faraday cage, thus eliminating interaction between conductor located in the duct and those located in neighbouring ducts.
