Abstract
The utility model discloses a full-dry-type low-smoke zero-halogen anti-flaming optical cable and aims to provide the cable with characteristics of green and environmental protection, good water resistance, high flame resistance and prevention of rat bites, facilitate a construction process of cable laying, guarantee transfer characteristics of the cable, and avoid environment pollution. The full-dry-type low-smoke zero-halogen anti-flaming optical cable comprises a cable core formed by at least two loose bushings twisting around a reinforcement component, wherein at least one tight buffer optical fiber is disposed inside the two loose bushings, the outside of the cable core is covered by steel belts, the outside of the steel belts is covered by an inner protection layer, and the outside of the inner protection layer is covered by an outer protection player.
Description
Technical field
The utility model relates to a kind of outdoor optical cable, especially dry type low-smoke non-halogen flame-retardant optical cable.
Background technology
Develop rapidly along with global IT application; Fiber to the home, and technology reaches its maturity; Make the security and the reliability of network seem particularly important, because human, the environmental-protecting performance of optical cable has also been proposed higher more comprehensively requirement the progressively attention of preserving the ecological environment and self is healthy.Traditional fire-retardant cable mostly with PVC as flame retardant plastics owing to contain objectionable impurities such as vinyl chloride in the raw material of igelite production, produce a large amount of cigarette and toxic gas during burning; For anti-sealing infilters in the cable, the mode that generally adopts ointment filling mode or ointment and dry type material water-proof material to mix, because ointment is difficult for shortcomings such as cleaning and poor performance at low temperatures, the construction more complicated.In addition, this type of optical cable scarcely has the mouse bite preventing function, is prone to cause because of animals such as mouse grab sting the communication disruption that causes.
Summary of the invention
The purpose of the utility model is to overcome deficiency of the prior art, and dry type low-smoke non-halogen flame-retardant optical cable is provided.Make that optical cable has environmental protection, water preventing ability is good, anti-flammability is high and characteristic such as mouse bite preventing, make things convenient for the work progress of cable laying, guarantee the transport property of cable, and can not pollute environment.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: dry type low-smoke non-halogen flame-retardant optical cable; Comprise by at least two loose sleeve pipes centering on the stranded cable core that forms of reinforcement that be provided with at least one tight tube fiber in the said loose sleeve pipe, said cable core is coating steel band outward; Steel band is coating sheath outward, and sheath is coating outer jacket outward.
Further, also be filled with waterstop between said cable core and the steel band, make optical cable have block-water performance.
Further, said tight tube fiber also is coated with one deck water blocking yarn outward, makes optical cable under the situation of waterstop breakage, still have block-water performance.
Further, said sheath and outer jacket are halogen-free low-smoke flame retardant material, make sheath and outer jacket have fire resistance, and can not pollute environment.
Further, also be filled with the layer of glass yarn between said sheath and the outer jacket, make optical cable have the characteristic of mouse bite preventing, and further improve the intensity of optical cable.
Further, said steel band is the two-sided plastic-steel that is coated with, and strengthens the mouse bite preventing characteristic of optical cable, and makes said steel band have the characteristic of anti-corrosion.
The beneficial effect of the utility model is: because sheath and outer jacket adopt halogen-free low-smoke flame retardant material, make optical cable have Halogen, hang down cigarette, low toxicity and have good flame retardant property; The steel band of two-sided plastic-coated and the use of glass fiber yarn make optical cable have good rodent-proof characteristic; Because the water blocking yarn and the waterstop that adopt the dry type high-performance to expand between each unit of cable core substitute traditional ointment, not only clean environment firendly, and convenient construction.
Description of drawings
Fig. 1 is the structural representation of the utility model dry type low-smoke non-halogen flame-retardant optical cable.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Among Fig. 1, dry type low-smoke non-halogen flame-retardant optical cable comprises by at least two loose sleeve pipes (2) around the stranded cable core that forms of reinforcement (1); Be provided with at least one tight tube fiber (3) in the said loose sleeve pipe (2), said cable core is coating steel band (7) outward, the outer sheath (8) that coating of steel band (7); Sheath (8) is outer to coat outer jacket (5), also is filled with waterstop (6) between said cable core and the steel band (7), makes optical cable have block-water performance; Said tight tube fiber (3) is outer also to be coated with one deck water blocking yarn (4), makes optical cable under the situation of waterstop breakage, still have block-water performance, and said sheath (8) is halogen-free low-smoke flame retardant material with outer jacket (5); Make sheath and outer jacket have fire resistance; And can not pollute, also be filled with layer of glass yarn (9) between said sheath (8) and the outer jacket (5), make optical cable have the characteristic of mouse bite preventing environment; And further improve the intensity of optical cable; Said steel band (7) is the two-sided plastic-steel that is coated with, and strengthens the mouse bite preventing characteristic of optical cable, and makes said steel band have the characteristic of anti-corrosion.
Because sheath 8 adopts halogen-free low-smoke flame retardant material with outer jacket 5, make optical cable have Halogen, hang down cigarette, low toxicity and have good flame retardant property; The steel band 7 of two-sided plastic-coated and the use of glass fiber yarn 9 make optical cable have good mouse bite preventing performance; Because the water blocking yarn 4 and waterstop 6 that adopt the dry type high-performance to expand between each unit of cable core substitute traditional ointment, not only clean environment firendly, and convenient construction.
