FIELD: electrical engineering.
EFFECT: provision of the possibility of distinguishing the functions of tubular cables after they are combined and in the convenience of identifying these cables. The tubular cable enclosed in a sheath with a coloured identification tape contains armour-protective tubes and a protective sheath layer. After the formation of each armoured tube, a hollow channel is formed in the centre of this tube. The hollow channel contains a wire cable, optical fibre or oil pipe. The protective sheath layer covers these armoured tubes. Several armour-protective tubes are located in one protective sheath layer. At the circumferential boundary of each armoured tube, at least one group of coloured identification tapes is suitably located.
SUBSTANCE: logging cables.
