TELECOMMUNICATION LINES CARRIED ON OVERHEAD TRANSMISSION LINES

Covers telecommunication lines which are carried on supports of OH high voltage lines. These regulations are not valid for constructions of conductors or cables with integrated optical fibres independent from their function which do not have simultaneously the function of a conductor or an earth wire.
