Abstract
The utility model discloses a loose tube layer stranded optical cable with an aluminum-plastic composite belt. The cable comprises fibers. A central portion is provided with a metal reinforcing element which is wrapped by a PE cushion layer. A plurality of optical fibers are around the metal reinforcing element in a circle. The plurality of optical fibers are sleeved with PBT loose tubes. Fiber paste is filled between each optical fiber and each PBT loose tube. All PBT loose tubes are wrapped by a yarn layer. Water blocking cable paste is filled between the yarn layer and the PBT loose tubes. The yarn layer is wrapped by the aluminum-plastic composite belt which is wrapped by a corrugated steel-plastic composite belt. The corrugated steel-plastic composite belt is wrapped by a PE sheath. The PE sheath is bonded outside the corrugated steel-plastic composite belt. According to the utility model, a plastic-aluminum composite belt longitudinal wrapping electric core is added, stretching resistance and side compression resistance ability is strong, flexibility and bending resistance ability of the cable are excellent, the water blocking cable paste is filled outside the reinforcing element and in a cable core, and moisture proofing and water blocking effects are ensured.
Description
Technical field:
The utility model relates to field fiber, relates in particular to a kind of loose sleeve layer strand type optical cable with aluminium-plastic tape.
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, 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, be easy to occur situation such as breakage, fracture by mistake.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 optical cable with aluminium-plastic tape, 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; Go wrong easily when growing apart from backguy, 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, be easy to occur the problem of situation such as breakage, fracture by mistake.
The technical scheme that the utility model adopts is:
A kind of loose sleeve layer strand type optical cable with aluminium-plastic tape, comprise optical fiber: central part has metal reinforcement, and metal reinforcement is wrapped with the PE bed course; Make a circle in metal reinforcement week and have some optical fiber; Some optical fiber all are set with PBT pine sleeve pipe outward, are filled with fine cream between optical fiber and the PBT pine sleeve pipe, and all PBT pine sleeve pipes are wrapped with the bundle layer; Prick between layer and the PBT pine sleeve pipe and be filled with the cable cream that blocks water; Prick layer and be wrapped with aluminium-plastic tape, aluminium-plastic tape is wrapped with the wrinkle composite steel-plastic belt, and the wrinkle composite steel-plastic belt is wrapped with the PE sheath.
Said wrinkle composite steel-plastic belt is bonded with the PE sheath outward.
Compared with prior art, the beneficial effect of the utility model is:
The utility model increases aluminum plastic composite belt longitudinal bag electricity core, its stretch-proof, and lateral pressure resistant is very capable, and optical cable pliability and counter-bending ability are good; 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.
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 optical cable with aluminium-plastic tape, comprise optical fiber: central part has metal reinforcement 1, and metal reinforcement 1 is wrapped with PE bed course 2; Making a circle in 1 week of metal reinforcement has some optical fiber 3, and 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; All PBT pine sleeve pipes 4 are wrapped with pricks layer 6; Prick between layer 6 and the PBT pine sleeve pipe 4 and be filled with the cable cream 7 that blocks water, prick layer 6 and be wrapped with aluminium-plastic tape 8, aluminium-plastic tape 8 is wrapped with wrinkle composite steel-plastic belt 9; Wrinkle composite steel-plastic belt 9 is wrapped with PE sheath 10, the wrinkle composite steel-plastic belt 8 outer PE sheaths 10 that are bonded with.
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.
