Seabed communication comprehensive cable with modified polypropylene sheath

The invention discloses a seabed communication comprehensive cable with a modified polypropylene sheath. The seabed communication comprehensive cable comprises a wire core, wherein a polyvinyl chloride water-blocking tape coating layer, a zinc-coated steel wire braided shielding sleeve and the modified polypropylene sheath sequentially sleeve the wire core from inside to outside, silica gel is filled between the wire core and the polyvinyl chloride water-blocking tape coating layer, silica gel is filled between the zinc-coated steel wire braided shielding sleeve and the modified polypropylene sheath, and the wire core comprises a first wire, a single-mode optical fiber, a coaxial radio frequency cable line and a second wire. The seabed communication comprehensive cable fabricated by the method has excellent water resistance, electrical conductivity and breakdown resistant performance, and moreover, the fabrication method is simple in step and is easy to promote. 本发明公开了种设有改性聚丙烯护套的海底通信综合电缆，该海底通信综合电缆包括线芯，线芯由内向外依
