Abstract
The utility model discloses a nonmetallic self-supporting optical cable, comprising optical fibers. The central part of the nonmetallic self-supporting optical cable is provided with fiber reinforced plastic (FRP) reinforcing wires, around which the plurality of optical fibers are arranged. Each optical fiber is externally sleeved with a loose tube. Fiber grease is filled between each optical fiber and each loose tube. The loose tubes are externally wrapped by an inner sheath. Waterproof cable compound is filled between the inner sheath and the loose tubes. The inner sheath is externally wrapped by an aramid fiber layer, which is externally wrapped by a PE outer sheath. The fiber reinforced plastic (FRP) reinforcing wires are made of glass fiber reinforced plastics (FRP). Through the addition of the FRP reinforcing wires at the central part of the cable, the nonmetallic self-supporting optical cable of the utility model achieves excellent mechanical performance and environmental performance. The whole cable, free of nonmetallic materials, achieves good insulating performance and can be erected on the same tower with high voltage lines of 200KV or higher. In addition, the inner sheath and the aramid fiber layer are added in the PE outer sheath, so that the shock resistance performance of the optical cable is greatly improved and can reach the bulletproof level.
Description
Technical field:
The utility model relates to field fiber, relates in particular to a kind of without the metal self-support cable.
Background technology:
Existing optical cable mostly is the optical fiber overcoat sleeve pipe, and cooperates the structure of oversheath, and its mechanical property is relatively poor, easily go wrong 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 bumped, be easy to occur the situations such as breakage, fracture by mistake by mistake.Therefore imagination provides a kind of new construction to solve this problem.
The utility model content:
The purpose of this utility model just provides a kind of without the metal self-support cable, the existing optical cable of solution mostly is the optical fiber overcoat sleeve pipe, and the structure of cooperation oversheath, its mechanical property is relatively poor, easily go wrong 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 bumped, be easy to occur the problem of the situations such as breakage, fracture by mistake by mistake.
The technical solution adopted in the utility model is:
A kind of without the metal self-support cable, comprise optical fiber: central part has fibre-reinforced plastics (FRP) line feeder, make a circle in fibre-reinforced plastics (FRP) line feeder week and have some optical fiber, every optical fiber all is set with loose sleeve pipe outward, be filled with fine cream between optical fiber and the loose sleeve pipe, all loose sleeve pipes are wrapped with inner sheath, are filled with the cable cream that blocks water between inner sheath and the loose sleeve pipe, inner sheath is wrapped with the aramid fiber layer, and the aramid fiber layer is wrapped with the PE oversheath.
Described fibre-reinforced plastics (FRP) line feeder is that glass fiber reinforced composite plastics (GFRP) are made.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can make optical cable have good mechanical property and environmental performance by increase the structure of FRP line feeder in section of cable center, and whole cable is without metal material, good insulation preformance, can with 200KV and above high-tension line wiring on the same tower; And in the PE oversheath, increasing inner sheath and aramid fiber layer, its shock resistance strengthens greatly, can reach shellproof rank.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, by embodiment the utility model is described in further detail:
A kind of without the metal self-support cable, comprise optical fiber: central part has fibre-reinforced plastics (FRP) line feeder 1, fibre-reinforced plastics (FRP) 1 week of line feeder makes a circle and has some optical fiber 2, every optical fiber 2 is outer all to be set with loose sleeve pipe 3, be filled with fine cream 4 between optical fiber 2 and the loose sleeve pipe 3, all loose sleeve pipes 3 are wrapped with inner sheath 5, be filled with the cable cream 6 that blocks water between inner sheath 5 and the loose sleeve pipe 3, inner sheath 6 is wrapped with aramid fiber layer 7, aramid fiber layer 7 is wrapped with PE oversheath 8, and fibre-reinforced plastics (FRP) line feeder 1 is made for glass fiber reinforced composite plastics (GFRP).
Above-described embodiment only is better embodiment of the present utility model, and in addition, the utility model can also have other implementations.Need to prove, under the prerequisite that does not break away from the utility model design, any apparent improvement and modification all should fall within the protection domain of the present utility model.
Claims (2)
1. one kind without the metal self-support cable, comprise optical fiber, it is characterized in that: central part has fibre-reinforced plastics FRP line feeder, making a circle in fibre-reinforced plastics FRP line feeder week has some optical fiber, and every optical fiber all is set with loose sleeve pipe outward, is filled with fine cream between optical fiber and the loose sleeve pipe, all loose sleeve pipes are wrapped with inner sheath, be filled with the cable cream that blocks water between inner sheath and the loose sleeve pipe, inner sheath is wrapped with the aramid fiber layer, and the aramid fiber layer is wrapped with the PE oversheath.
