Preferably, described cable is followed successively by insulated wire cores, semiconductive waterstop, lead sheath, asphalt corrosion resistant layer, inner sheath from inside to outside.

Further, described inner covering comprises pitch and netted polypropylene rope.

Further, described sleeve pipe is gapless stainless steel tube.

Further, described fiber cable jacket is pe sheath.

As mentioned above, a kind of photoelectric composite submarine cable device of the present utility model, has following beneficial effect: the lead sheath energy radial water-resisting that the utility model adopts, the anticorrosion glue-line of the pitch of lead sheath outside can guarantee effectively that lead sheath is not subjected to the corrosion of seawater, and the utility model is provided with wire armoring, can make the utility model can bear self-weight tension and the external tensile force of sufficient length submarine cable, most importantly this device comprises cable and optical cable simultaneously, in electric energy transmitting, also realized the transmission of the communication information.

Embodiment

The structure that Figure of description illustrates, ratio, size etc., equal contents in order to coordinate specification to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this specification, quote as " on ", the term such as D score, 'fornt', 'back', " centre ", also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the utility model.

Be illustrated in figure 1 the cross section structure schematic diagram of photoelectric composite submarine cable of the present utility model, the utility model is comprised of oversheath and the multi-cable 1 and the optical cable 4 that are positioned at oversheath, at the gap portion of oversheath inside cable 1 and optical cable 4, is provided with non-hygroscopic and fills 3.Described oversheath is followed successively by inner covering 21, wire armoring 22 and serving 23 from inside to outside, and in order to improve waterproof effect, described inner covering 21 comprises pitch and netted polypropylene rope.The cross section structure schematic diagram of optical cable 4 as shown in Figure 3, optical cable 4 comprises optical fiber 41, described optical fiber 41 outer cover have sleeve pipe 43, between optical fiber 41 and sleeve pipe 43, be filled with optical fiber ointment 42, sleeve pipe 43 outsides are equipped with wire armoring 44 and fiber cable jacket 46 successively, between described wire armoring 44 and fiber cable jacket 46, fill dope 45.Utilize this structure to meet of the present utility modelly to block water, the performance of tensile property and lateral pressure resistant power.
