FIELD: means for underground laying of composite cable including a fiber-optic cable and electric communication and/or control cables. SUBSTANCE: the sleeve has a body with a tray placed in it, secured on it are the reserve stock of optical modules and joints of optical fibers, and assemblies of connection of copper cores, protective metal detachable jacket, in which in a spaced relation positioned is the body made of polymeric material and consisting of the central part and cylindrical cap. The space between the jacket and the body is filled with foamed polyurethane hermetic. The central part has the first branch pipe for hermetic input of sections of the composite cable and several additional branch pipes for branching off the electric cables. The additional branch pipes are made for installation of caps in them. The cross-section of the hole of the first branch pipe is oval. Installed inside the body is a bracket made in the form of two metal rods, with the bearing member made in the form of transverse cross-pieces fastened on their first ends. The second ends of the rods are fixed in the holes of the central part, at a certain distance from the second ends the rods are bent so that the bearing member is positioned at a distance from the axis of symmetry of the cylindrical cap. The metal cores and the assemblies of connection of the copper cores are attached to a metal grate that is installed on the first side of the bearing member, and the tray is attached to the second side of the bearing member. The aluminum sheath of each section of the composite cable is connected to the copper wire to make a cross-piece inside the body, or to the copper core of the insulated sealed wire for making grounding outside the jacket, the central part and the cylindrical cap are made with annular flanges, with a thermosetting tube fitted on them. EFFECT: enhanced strength and reliability of the sleeve and expanded its functional potentialities due to the fact that the cable taps are made with copper cores, and the connection of composite cables of various types in it. 9 cl, 4 dwg
