Description

Irregular hexagonal low-friction pipeline composite cable

Technical Field

The utility model relates to a composite cable especially relates to a composite cable of irregular hexagon low friction pipeline belongs to the communication equipment field.

Background

Due to the specific application scene of the composite cable for the pipeline, in the laying process of the composite cable in the pipeline, the friction force between the composite cables is large due to the close contact between the composite cables, and certain difficulty is brought to the laying of the composite cables. In the prior art, the cross sections of the optical cable and the electric cable are circular, after more optical cables and electric cables are laid in the pipeline, certain extrusion exists between the optical cables and the electric cables, so that the friction force between the optical cables and the electric cables is high, the composite cable can pass through the pipeline by large external force, and the construction efficiency is reduced.

Disclosure of Invention

The utility model aims at providing a can reduce compound cable of frictional force between the compound cable, be applicable to the pipeline and use the scene.

In order to achieve the purpose, the utility model adopts the following technical scheme:

An irregular hexagonal low-friction pipeline composite cable comprises a central reinforcing part which is placed in the central position and used for improving the tensile strength of the composite cable, a plurality of optical fibers are arranged around the central reinforcing part, sleeves are arranged outside the central reinforcing part and the optical fibers, water-blocking materials are filled in the sleeves, an outer sheath is arranged outside each sleeve, the outer sheath is integrally arranged to be an irregular hexagon, the long side and the short side of the irregular hexagon are preferably arranged alternately, and a round hole is formed below the short side of the outer sheath and used for placing a copper wire; the long edge of the outer sheath is provided with a tearing opening.

Preferably, the central reinforcing member is a glass fiber material.

Preferably, the sleeve is a double-layer sleeve made of PBT material and PC material.

Preferably, the optical fiber is a silica glass single mode optical fiber.

Preferably, the water-blocking material is prepared by blending a gelling agent, a preservative, a viscosity regulator and a hydrogen removing agent.

The beneficial effects of the utility model reside in that, the design of the irregular hexagon of oversheath reduces the surperficial friction of compound cable, makes laying of compound cable degree of difficulty reduce, has reduced construction cost simultaneously, has improved the efficiency of construction. And placing the copper conductor in a sharp corner outside the sheath, and twisting the sleeve at the vacant position to increase the optical communication capacity of the composite cable.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown, an irregular hexagonal low-friction conduit composite cable 100 is provided, in order to reduce the friction between the composite cable and external equipment, particularly other composite cables, as it traverses the conduit, and is generally configured as an irregular hexagon in the outer sheath 104 of the composite cable 100, preferably with alternating long sides and short sides.

The round hole 105 is formed in the lower portion of the short side of the outer sheath 104, the round hole 105 is used for placing a copper wire, and the composite cable outer sheath 104 has the advantages that one more space is formed in the composite cable outer sheath 104, a sleeve can be stranded, and optical communication capacity of the composite cable is increased.

The tearing opening 106 is formed in the long edge of the outer sheath 104, the tearing rope is matched with the tearing opening 106 to work, the sheath is torn conveniently during engineering construction to obtain a cable core, construction time is greatly saved, and working efficiency is improved.

The interior of composite cable 100 includes a central strength member 107 centrally disposed therein for increasing the tensile strength of the composite cable, the central strength member 107 being a fiberglass material; a plurality of optical fibers 101 are arranged around the central reinforcing member 107, and the optical fibers 101 are quartz glass single-mode optical fibers; a sleeve 103 is arranged outside the central reinforcing member 107 and the optical fiber 101, a water blocking material is filled in the sleeve 103, and an outer sheath 104 is arranged outside the sleeve 103. The sleeve 103 is a double-layer sleeve made of PBT material and PC material.

The water blocking material 102 in the sleeve 103 is formed by mixing a gelling agent, a preservative, a viscosity regulator and a dehydrogenation agent.
