FIELD: means for assembly of sleeves on the supports of the power line at suspension of a ground-wire cable with a built-in optical cable or dielectric optical cable from them. SUBSTANCE: the sleeve has joints of optical fibers located in the cradles at least of one holder installed on a metal bracket fixed in the holes of two bushes welded with their ends to the flat base of the sleeve that is closed with a blind cover. Sleeve sealing is made with the aid of two sealing gaskets tightened at bolting of the sleeve flat base and the cover flange. The joined ends of the ground-wire cable with the built-in optical cable or the ends of the suspended dielectric optical cable are inserted in the sleeve through the inlet branch pipes of the rectangular flat base. Made in each branch pipe for assembly of the ends of the ground-wire cable is a fastening of the wires of the ground-wire cable, which is ensured by the use in the inner cylindrical cavity of the inlet branch pipe of a tapered bush and four steel cams, whose teeth when screwed in the inlet branch pipe by the inner stop nut holding on the steel wires of the ground-wire cable, reliably fix them. For convenience of assembly, before installation and screwing-in of the inner stop nut, the cams are freely inserted in the inner cavity of the branch pipe from its end on the wires of the ground-wire cable, and then fixed by the inner stop nut through a V-ring. EFFECT: reduced weight of the device components simultaneously lifted on the support of the power line, enhanced reliability of fixing of wires of the ground-wire cable, synthetic threads or glass plastic rods of the optical cable in the sleeve inlet branch pipes. 13 cl, 6 dwg
