Improve further in, be provided with gasket for packing in described steel band, the side of described gasket for packing is provided with steel wire.
Improve further in, described outer jacket includes sheath and insulation screen.
Improve further in, be additionally provided with reinforced core in described cable core, described reinforced core is peripheral stranded and is wrapped in described cable core.Reinforced core is set so that the bending resistance of communication cable improves, additionally, reinforced core is peripheral stranded and is wrapped in cable core so that the cable in insulating barrier becomes as a whole, further improve the communications cable radially counter-bending/distortion performance.
Improve further in, described reinforced core is arranged at intervals with some radially protrusion and separate reinforcement.Interval arranges the effect of reinforcement and is in that so that pullling communication cable in the longitudinal direction, this pulling force of the more effective reply of internal core；Separate reinforcement, it is therefore an objective to reinforcement is set cable can not be hindered to arrange in insulating barrier.
Improve further in, described reinforcement is in cross in terms of cross section, and described reinforced core is centrally located.
Improve further in, the upper surface of described jointing is provided with flexible clamp piece, and the lower surface of described jointing is provided with connection draw-in groove, and the rear end face of described connection draw-in groove forms inclined-plane.
Improve further in, the rear end of described communication cable-end is provided with protection suite.
Compared with prior art, the invention has the beneficial effects as follows: by power line, optical cable and data wire are placed jointly, not only convenient construction, save raw material, also reduce cost, it is ensured that the transmission of each unit signal does not interfere with each other, excellent properties when each self-sustaining is individually transmitted；Effectively reducing signal attenuation and interference, efficiency of transmission is higher；In addition; PVC flame-retardant sheath is set and is possible to prevent ignition of cable; in PVC flame-retardant layer, it is provided with medium density polyethylene layer simultaneously; improve uvioresistant and the antioxidative effect of cable, and be provided externally with PBT pine pipe box layer at optical fiber, because optical fiber is the filament pulled into by quartz; because of its very fragile, frangibility; so pine tube layer is for protecting the effect of optical fiber, and in cable core, it is filled with steel wire and gasket for packing, effectively strengthens the intensity of optical cable；Interval arranges the effect of reinforcement and is in that so that pullling communication cable in the longitudinal direction, this pulling force of the more effective reply of internal core；Separate reinforcement, it is therefore an objective to reinforcement is set cable can not be hindered to arrange in insulating barrier.
