Abstract
The utility model discloses a direct-buried loose tube layer stranded optical cable with prevention of a rodent. The optical 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 arranged around the metal reinforcing element in a circle. The plurality of optical fibers are sleeved with PBT loose tubes. Fiber paste is filled between the optical fibers and the PBT loose tubes. 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 an aluminum-plastic composite belt which is wrapped by a PE inner protection layer. The PE inner protection layer is wrapped by a water blocking layer which is wrapped by a corrugated steel-plastic composite belt which is wrapped by a PE sheath. The water blocking layer is formed by coiling a polyethylene belt. According to the utility model, a structure with double sheaths in coordination with longitudinal covering of double metal belts is added and employed, drawing resistance and side compression resistance ability is strong, flexibility and bending resistance ability of the optical cable is good, the optical cable has the capacity of preventing bites of the rodent at the same time, the water blocking cable paste is filled outside the reinforcing element and in a cable core, the water blocking layer is added, moisture resisting and water blocking effects are ensured, and the use of the cable is not influenced even an outer sheath has small damage.
Description
Technical field:
The utility model relates to field fiber, relates in particular to a kind of anti-rodentine direct-burried loose sleeve layer strand type optical 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, 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; Do not possess simultaneously the ability that anti-rodent is destroyed, local in a single day laying that has this kind animal to haunt is easy to the destruction that bitten.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 anti-rodentine direct-burried loose sleeve layer strand type optical 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; 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; Do not possess simultaneously the ability that anti-rodent is destroyed, the local problem that is easy to bitten and destroys of in a single day laying that has this kind animal to haunt.
The technical scheme that the utility model adopts is:
A kind of anti-rodentine direct-burried loose sleeve layer strand type optical cable, comprise optical fiber: central part has metal reinforcement, and metal reinforcement is wrapped with the PE bed course; Making a circle in metal reinforcement 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 the bundle layer, prick between layer and the PBT pine sleeve pipe and are filled with the cable cream that blocks water, and prick layer and are wrapped with aluminium-plastic tape; Aluminium-plastic tape is wrapped with the PE sheath; The PE sheath is wrapped with water blocking layer, and water blocking layer is wrapped with the wrinkle composite steel-plastic belt, and the wrinkle composite steel-plastic belt is wrapped with the PE sheath.
Said water blocking layer is that the coiling of tygon band forms.
Compared with prior art, the beneficial effect of the utility model is:
The utility model increases the structure that adopts the vertical bag of two sheaths cooperation bimetallic strips, its stretch-proof, and lateral pressure resistant is very capable, and optical cable pliability and counter-bending ability are good, possess the ability that anti-rodent bites simultaneously; Be full of the cable cream that blocks water outside the reinforcement and in the cable core, and be added with water blocking layer, guarantee protection against the tide, block-water effect, even oversheath has tiny breakage also not influence use.
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 anti-rodentine direct-burried loose sleeve layer strand type optical cable, 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 PE sheath 9; PE sheath 9 is wrapped with water blocking layer 10; Water blocking layer 10 is wrapped with wrinkle composite steel-plastic belt 11, and wrinkle composite steel-plastic belt 11 is wrapped with PE sheath 12, and water blocking layer 10 forms for the coiling of tygon band.
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.
Claims (2)
1. an anti-rodentine direct-burried loose sleeve layer strand type optical cable comprises optical fiber, and it is characterized in that: central part has metal reinforcement; Metal reinforcement is wrapped with the PE bed course, makes a circle in metal reinforcement week to have some optical fiber, and some optical fiber all are set with PBT pine sleeve pipe outward; Be filled with fine cream between optical fiber and the PBT pine sleeve pipe, all PBT pine sleeve pipes are wrapped with the bundle layer, prick between layer and the PBT pine sleeve pipe and are filled with the cable cream that blocks water; Prick layer and be wrapped with aluminium-plastic tape, aluminium-plastic tape is wrapped with the PE sheath, and the PE sheath is wrapped with water blocking layer; Water blocking layer is wrapped with the wrinkle composite steel-plastic belt, and the wrinkle composite steel-plastic belt is wrapped with the PE sheath.
