An overground cable system, in particular an overground electric power transmission system, comprises a series of spaced upright supports between which extend at least two cables or conductors (22,22') each of which is prone to rotation about its own longitudinal central axis on the accretion of wet snow and ice thereon, the individual cables being mutually restrained by, for example, spacer means (24) reacting between adjacent cables or conductors (22,22') at intervals therealong. |
