Description
Technical field
The utility model relates to a kind of indoor and outdoor all dielectric environmental protection flame retardant termite-proof optical cable, belong to communication cable field, mainly can cable shaft between outdoor environment, building, in communication base station, use in communications equipment room, there is Signal transmissions and termite-proof dual-use function.
Technical background
Along with the development of optical-fibre communications, the use of optical cable is more and more universal, and different environments for use requires different to optical ca ble protection.In the area that some termites of south are more serious, often there is the situation that optical cable is bitten broken by termite, bring great difficulty to line upkeep.
Major measure termite-proof at present have chemistry termite-proof, physics is termite-proof.Chemistry is termite-proof mainly adds some repellent agent in cable sheath material, and as Niran, dieldrite etc., chemical termite-proof meeting pollutes surrounding environment, and the termite-proof term of validity still be can not determine; The object that physics is termite-proof mainly utilizes the smoothness in the hardness of plastics and cable just face to reach, conventional plastics have semirigid PVC, modification high-density polyethylene, but semirigid PVC is not suitable for indoor environment because can produce a large amount of poisonous and hazardous gas when burning, modification high-density polyethylene is same because not fire-retardant being also not suitable for uses in indoor scenarios.
Utility model content
For above-mentioned technical matters, technical problem to be solved in the utility model is to provide a kind of indoor and outdoor all dielectric environmental protection flame retardant termite-proof optical cable, effectively can solve the defect that existing termite-proof optical fiber is not suitable for indoor environment use.
For solving the problems of the technologies described above, technical solution of the present utility model is achieved in that a kind of indoor and outdoor all dielectric environmental protection flame retardant termite-proof optical cable, described optical cable comprises cable core and sheath, wherein said cable core is by non-metal reinforcement member 3 built-in fiber 1 and fill out that core 2 is stranded to be made, described optical fiber 1 and fill out core 2 also around center part 4, wherein said sheath comprises inner sheath 5 and oversheath 6.
Further, described optical fiber 1 is bare fibre, coated fiber or tightly packaged fiber;
Further, the quantity of described optical fiber 1 is one or more;
Further, described reinforcement 3 is one or more in organdy fiber, glass fiber tape, aramid fiber or basalt fibre;
Further, described center part 4 is FRP, KFRP or GFRP;
Further, the material of described inner sheath 5 is low smoke halogen-free flame-retardant polyolefin, low cigarette zero halogen fire retardant polyolefin or flame retardant polyurethane;
Further, the material of described oversheath 6 is high rigidity environmental-protection fire-resistant nylon;
Further, the external diameter≤7mm of described optical cable.
The beneficial effects of the utility model: oversheath of the present utility model is protected as ground floor, adopt nylon or high density polyethylene that hardness is high, replace in protecting sleeve of optical cable, adding repellent agent in prior art.Not only effectively extend the optical cable termite-proof life-span, and to zero environmental.
Enhancement Layer of the present utility model adopts glass fibre to protect as the second layer, termite gnaw bite touch glass layer time, glass dregs stimulates termite oral cavity, thus effectively prevents termite from continuing to destroy optical cable.
The version that the utility model adopts all dielectric fire-retardant, replaces in optical cable, arranging the high metal armor layers of intensity in prior art.Not only in indoor use, but also can lay under built on stilts, buried condition, anti-lightning strike safe and reliable.Meet uvioresistant, oil resistant, the environmental requirement such as corrosion-resistant, fire-retardant, can resist electromagnetic interference (EMI), meet safety standard, electrical isolation safety produces without electric spark.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of indoor and outdoor of the present utility model all dielectric environmental protection flame retardant termite-proof optical cable.
Embodiment
Below in conjunction with drawings and Examples, structure of the present utility model and principle of work are described in further detail.
As shown in Figure 1, all dielectric environmental protection flame retardant termite-proof optical cable of indoor and outdoor disclosed in the utility model, it has cable core and sheath.Wherein cable core is by non-metal reinforcement member 3 built-in fiber 1 with fill out that core 2 is stranded to be made, optical fiber 1 and fill out core 2 also around center part 4; Wherein sheath comprises inner sheath 5 and oversheath 6.
The quantity of optical fiber 1 can be one or more, and in the present embodiment, the quantity of optical fiber 1 is two; Alternatively, optical fiber 1 is bare fibre, coated fiber or tightly packaged fiber.
Reinforcement 3 is one or more in organdy fiber, glass fiber tape, aramid fiber or basalt fibre.Reinforcement 3 is as second layer protective seam, and glass material is pre-termite-proof erosion effectively; Center part 4 is FRP, KFRP or GFRP.
And then around cable core extrusion molding inner sheath 5 and oversheath 6 successively.Alternatively, the material of inner sheath 5 is low smoke halogen-free flame-retardant polyolefin, low cigarette zero halogen fire retardant polyolefin or flame retardant polyurethane; The material of oversheath 6 is high rigidity environmental-protection fire-resistant nylon.Because oversheath 6 adopts the environmental-protection fire-resistant nylon of high rigidity as ground floor protective seam, and optical cable smooth surface, termite is had no way of end opening, and then effectively can resist the destruction of termite tooth.Simultaneously because choosing in this optical cable has inner sheath 5 and the oversheath 6 of environmental protection flame retardant, optical cable can not produce toxic and harmful when burning, this optical cable not only can be used in outdoor environment, also can cable shaft between building, in communication base station, in communications equipment room in use.Preferably, the cable outer diameter that the utility model provides is less than or equal to 7mm.
The embodiment that the utility model is recorded, only for being described the utility model, does not form the restriction to right.Other equivalent in fact substituting, all in protection domain of the present utility model that those skilled in that art can expect.
