Abstract

The utility model belongs to the technical field of cables and particularly relates to a cold-resistant shield cable. An inner shielding layer, an ethylene propylene rubber insulating layer, an outer shielding layer and a braiding layer are sequentially coated on the external surface of a tin-plated steel wire conductor to form a main wire core, and three main wire cores are in triangle arrangement. A rubber filling core is arranged in the middle of the three main wire cores, and a control core or an optical fiber control core is arranged between the adjacent main wire cores. The main wire cores, the control core and the optical fiber control core are twisted and extruded with a non-woven fabric layer. An inner sheath, a first conductive belt, a second conductive belt and an outer sheath are sequentially coated outside the non-woven fabric layer. Grounding wires are uniformly distributed between the first conductive belt and the second conductive belt. The control core is characterized in that the external surface of the conductor is coated with a fluoroplastic insulating layer to form a wire core; the filling cores are arranged among the twisted three wire cores and on the external surfaces to form the control core; the filling core layer is coated outside the optical fiber to form the optical fiber control core. The utility model can feed the signal back in real time in case of fault or abnormal conditions of a shield machine.
