Abstract
The utility model discloses a fireproofing optical cable, include the cable core, the cladding has the fire prevention insulating layer outside the cable core, and the fire prevention insulating layer is equipped with the fire prevention sheath outward, and the cable core has two 1 kinds, and one kind is used the protection tube to be using central reinforcing element as the axle center as cable core, another kind, strands the cable core of compriseing many protection tubes on every side, contains one or multifiber and optic fibre oleamen in the protection tube, and wrap -around fire prevention insulating layer wraps or wraps from north to south for winding outside the cable core, the utility model discloses can not be burnt under the naked light state, more can do not not produced the harmful substance of smog and toxin, when tunnel, market, office building, when the conflagration appears in densely populated place such as public, when stopping harmful substance and produce, guarantee communication and transmission of digital informations.
Description
Technical field
Optical cable, particularly a kind of fireproof cable that the densely populated places such as the utility model relates in tunnel, market, office building, public place use.
Background technology
Along with the development of China's economy, urban infrastructure project constantly rises to, at present in tunnel, the optical cable that uses of market, office building, the densely populated place such as public place mainly adopts low-smoke halogen-free flame-retardant sheath optical cable, but this optical cable is be in fired state when naked light, the communication of optical cable, data transmission are by along with burned and occur the communication of optical cable, the interruption of data transmission, this optical cable is the smog that can produce some when burned simultaneously, brings certain harmfulness to fire control and disaster rescue.Therefore, a kind of optical cable that can not be burned under naked light state is needed.
Utility model content
In order to overcome the above problems, the utility model provides a kind of fireproof cable.
The technical solution adopted in the utility model is:
A kind of fireproof cable, comprise cable core, described cable core is coated with fire proof heat-insulation layer; be provided with fireproof outside described fire proof heat-insulation layer, described cable core has two 1 kinds, and one take protection tube as cable core; another kind is with center reinforcing element for axle center, around the stranded cable core be made up of many protection tubes.
Containing one or more optical fiber and optical fiber ointment in described protection tube.
The fire proof heat-insulation layer of described cable core outer cladding is wrapped or vertical bag.
The utility model has the advantages that: can not be burned under naked light state, more can not produce the objectionable impurities of smog and toxin, when fire appears in tunnel, market, office building, the densely populated place such as public, stopping while objectionable impurities produces, to ensure the transmission of communication and data.
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 the utility model protection tube;
Fig. 2 is the stranded structural representation of the utility model center reinforcing element and protection tube;
The structural representation of Fig. 3 to be the utility model with protection tube be cable core;
Fig. 4 is that the utility model is with center reinforcing element and the stranded structural representation for cable core of protection tube.
Wherein: 1, optical fiber; 2, optical fiber ointment; 3, protection tube; 4, center reinforcing element; 5, fire proof heat-insulation layer; 6, fireproof.
Embodiment
As Figure 1-4, a kind of fireproof cable, comprise cable core, cable core is coated with fire proof heat-insulation layer 5, its material is polymeric material, fireproof 6 is provided with outside fire proof heat-insulation layer, its material is polymeric material, described cable core has two 1 kinds, one is for cable core (as Fig. 3) with protection tube 3, the material of protection tube is metal or nonmetal, metal is generally copper, aluminium, stainless steel, nonmetal is PBT or other polymerizable material, another kind is for axle center with center reinforcing element 4, the stranded cable core (as Fig. 4) be made up of many protection tubes around, the material of center reinforcing element is metal or nonmetal, containing one or more optical fiber 1 and optical fiber ointment 2 in protection tube, the fire proof heat-insulation layer of cable core outer cladding is wrapped or vertical bag, the utility model can not be burned under naked light state, more can not produce the objectionable impurities of smog and toxin, work as tunnel, market, office building, when there is fire in the densely populated place such as public, while stopping objectionable impurities generation, ensure the transmission of communication and data.
