Abstract

Aerial cable for telecommunications signal transmission along high-voltage networks has a dielectric of pref. foamed or compact polyethylene, and has a core formed by using a coaxial line whose inner conductor is insulated relative to the return conductor so as to be protected against the high voltages, and is connected by capacitors to a corresponding centre. The core has at least 4 coaxial lines, cabled in star formation, with the high-voltage insulating dielectric, and an insulating sheath surrounding the concentric return conductor. The coaxial lines are enclosed by an electrically conducting envelope which is earthed and is surrounded by a traction-protecting armour. The spaces between the coaxial lines within the envelope are filled with a stable material. Pref. each pair of diametrically opposed external conductors constitutes a symmetrical phantom circuit.
