Embodiment Construction

[0024] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0025] Such as figure 1 As shown, the full-section water-blocking and sealing multi-signal composite cable includes a cable core 1, an inner sheath 2, a shielding layer 3, and an outer sheath 4. The cable core 1 is provided with a wrapping tape 5, and the wrapping tape 5 is extruded outside Polyurethane inner protective layer 2 with a thickness of 1.5mm and polyurethane outer protective layer 4 with a thickness of 2mm. Between the outer protective layer 4 and the inner protective layer 2 is a shielding layer 3 braided by galvanized steel wires with a diameter of 0.3mm. The shielding layer 3 and There is also a wrapping tape 5 between the outer sheath 4, and...

Abstract

The invention discloses a total cross-section water-stop sealing multi-signal composite cable including a cable core, an inner protection layer, a shielding layer and an outer protection layer. The cable core is externally provided with a wrapping tape. The inner protection layer and the outer protection layer are formed outside the wrapping tape through extrusion. The shielding layer is formed ina braiding manner between the outer protection layer and the inner protection layer. A wrapping tape is also arranged between the shielding layer and the outer protection layer. The cable core is formed by twisting an optical unit, a power line, a coaxial line, a twisting pair and a filler rope in a spiral manner. The twisting gap of the cable core and the gap in the shielding layer are both filled with filler glue. Each of the power line, the coaxial line, the twist pair and the outer protection layer in the composite cable is therein provided with a braided shielding layer, water-resistingand wear-resisting chemical material is adopted for a sheath, and the gaps among the different units are filled with water-stop filler glue. Therefore, the composite cable provided by the invention has a capability of total cross-section high pressure resistance and water leakage prevention. In underwater application, the composite cable can provide optical fibers for transmitting optical signalsand can also provide a power line for transmitting control signals, a coaxial line for transmitting radio frequency signals and a twisting pair for transmitting communication signals. Besides, the composite cable provided by the invention is small in product size, diversified in functions and stable in transmission.

Description

Technical field [0001] The invention relates to the technical field of fiber optic cable and cable preparation, in particular to a full-section water-blocking and sealing multi-signal composite cable and a preparation process thereof. Background technique [0002] my country is a major maritime development country, and it is very active in maritime transportation, offshore oil fields, offshore power generation and maritime communications. In today's society, the development and utilization of water resources has become the development direction and trend of all countries in the world. More and more equipment is used in underwater operations, not only in military fields such as submarines, aircraft carriers, warships, and manned submersibles, but also in civilian tunnels. , Underwater monitoring systems, ships, water power plants, island communications, water platform communications and other fields also need a communication optical cable product that can be used at a depth of 500...
