Abstract

The utility model discloses a loose tube layer stranded waterline cable which comprises fibers. A central part is provided with a central phosphorized steel wire which is wrapped by a PE cushion layer. A plurality of fibers are arranged around the central phosphorized steel wire. The plurality of fibers are sleeved by PBT loose tubes. Fiber paste is filled between the fibers and the PBT loose tubes. All PBT loose tubes are wrapped by an aluminum-plastic composite belt. Water blocking cable paste is filled between the PBT loose tubes and the aluminum-plastic composite belt. The aluminum-plastic composite belt is wrapped by a first PE sheath which is wrapped by a water blocking belt. The water blocking belt is wrapped by a corrugated steel-plastic composite belt which is wrapped by a secondary PE sheath. A plurality of phosphorized steel wires are arranged around the secondary PE sheath in a circle. The phosphorized steel wires are wrapped by an MDPE outer sheath. According to the utility model, through adding the phosphorized steel wires, the steel-plastic composite belt and the aluminum-plastic composite belt in the MDPE outer sheath, high strength side pressure and stretching can be resisted, shock resistance capacity reaches a bulletproof level, the water blocking cable paste is filled outside a reinforcing element and in a cable core, moisture resisting and water blocking effects are ensured, at the same time, a water blocking belt layer is added in the MDPE outer sheath, and the cable can be integrally installed under water.

Description

A kind of loose sleeve layer strand type Water line optic cable

Technical field:

The utility model relates to field fiber, relates in particular to a kind of loose sleeve layer strand type Water line optic cable.

Background technology:

Mostly existing optical cable is that optical fiber is with sleeve pipe outward, and cooperates the structure of oversheath, and its mechanical property is relatively poor; Go wrong easily when growing apart from backguy, secondly cable outer sheath adopts the PE sheath usually, and its pressure-proof and snap-resistent ability is relatively poor; In case dug or bump by mistake by mistake; Be easy to occur situation such as breakage, fracture, do not have waterproof ability simultaneously, can't use when setting up under water.Therefore imagination provides a kind of new construction to solve this problem.

The utility model content:

The purpose of the utility model just provides a kind of loose sleeve layer strand type Water line optic cable, solves existing optical cable and is mostly that optical fiber is with sleeve pipe outward, and cooperate the structure of oversheath; Its mechanical property is relatively poor, goes wrong easily when growing apart from backguy, and secondly cable outer sheath adopts the PE sheath usually; Its pressure-proof and snap-resistent ability is relatively poor, in case dug or bump by mistake by mistake, is easy to occur situation such as breakage, fracture; Simultaneously do not have waterproof ability, the problem that can't use when setting up under water.

The technical scheme that the utility model adopts is:

A kind of loose sleeve layer strand type Water line optic cable comprises optical fiber: central part has center phosphatization steel wire, and center phosphatization steel wire is wrapped with the PE bed course; Making a circle in center phosphatization steel wire week has some optical fiber, and some optical fiber all are set with PBT pine sleeve pipe outward, is filled with fine cream between optical fiber and the PBT pine sleeve pipe; All PBT pine sleeve pipes are wrapped with aluminium-plastic tape; Be filled with the cable cream that blocks water between PBT pine sleeve pipe and the aluminium-plastic tape, aluminium-plastic tape is wrapped with the PE sheath one time, and one time the PE sheath is wrapped with waterstop; Waterstop is wrapped with the wrinkle composite steel-plastic belt; The wrinkle composite steel-plastic belt is wrapped with secondary PE sheath, and secondary PE sheath periphery makes a circle and has some phosphatization steel wires, and the phosphatization steel wire is wrapped with the MDPE oversheath.

Said waterstop forms for the polyethylene film material coiling.

Compared with prior art, the beneficial effect of the utility model is:

The utility model is through increasing the structure of phosphatization steel wire and composite steel-plastic belt, aluminium-plastic tape in the MDPE oversheath, pliability and counter-bending ability are good, can resist high strength side pressure and stretching, and impact resistance reaches level of ballistic protection; Be full of the cable cream that blocks water outside the reinforcement and in the cable core, guarantee protection against the tide, block-water effect, increased water blocking tape layer in the MDPE oversheath simultaneously, but made the cable integral erection under water.

Description of drawings:

Accompanying drawing 1 is the utility model structural representation.

Embodiment:

Below in conjunction with accompanying drawing, the utility model is done further explain through embodiment:

A kind of loose sleeve layer strand type Water line optic cable comprises optical fiber: central part has center phosphatization steel wire 1, and center phosphatization steel wire 1 is wrapped with PE bed course 2; Make a circle in 1 week of center phosphatization steel wire and have some optical fiber 3; The some optical fiber 3 outer PBT pine sleeve pipes 4 that all are set with are filled with fine cream 5 between optical fiber 3 and the PBT pine sleeve pipe 4, and all PBT pine sleeve pipes 4 are wrapped with aluminium-plastic tape 6; Be filled with the cable cream 7 that blocks water between PBT pine sleeve pipe 4 and the aluminium-plastic tape 6; Aluminium-plastic tape 6 is wrapped with 8, PE sheaths 8 of a PE sheath and is wrapped with waterstop 9, and waterstop 9 is wrapped with wrinkle composite steel-plastic belt 10; Wrinkle composite steel-plastic belt 10 is wrapped with secondary PE sheath 11; Secondary PE sheath 11 peripheries make a circle and have some phosphatization steel wires 12, and phosphatization steel wire 12 is wrapped with MDPE oversheath 13, and said waterstop 9 forms for the polyethylene film material coiling.

The foregoing description is merely the preferred implementation of the utility model, and in addition, the utility model can also have other implementations.Need to prove that under the prerequisite that does not break away from the utility model design, any conspicuous improvement and modification all should fall within the protection domain of the utility model.
