Description

Flame-proof damp-proof data cable
Technical field
The invention relates to field of cable technology, is specifically related to flame-proof damp-proof data cable.
Background technology
Data cable is the transmission medium of current known ideal broadband access network, and it has low cost of manufacture, structure is simple, expandability good and be convenient to the advantages such as network upgrade.
The common problem that existing data cable ubiquity anti-flammability is poor, and along with the whole society's improving constantly the attention degree of safety and environmental protection, for occasions such as such as skyscraper, public venue, public entertainment facility, subway, station, airport and oil, hospital's chemical industry and even nuclear power stations, the common data cable without fire resistance will be faded out gradually.
In addition, also has water to the threat of data cable, except being affected except being intake by data cable crust, also have data cable beginning water-immersed possibility, the twisted wire of data cable inner tight can promote that capillary is reacted, and can the water outside great distances be sucked in data cable, destroy the electrical characteristic of data cable, thus data cable may be caused to lose transmittability, once break down, loss will be no longer cable itself.
Therefore, the data cable tool that exploitation had not only had desirable high flame retardant effect but also had an excellent humidity resistance is of great significance.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art and provides a kind of fire resistance and humidity resistance excellence, and the flame-proof damp-proof data cable that signal attenuation is little, laser propagation effect is good.
The object of the invention is achieved through the following technical solutions:
Provide flame-proof damp-proof data cable, comprise sheath and be arranged at the cable core in sheath, also comprise the insulated wire cores with different colours, the insulated wire cores of every two different colours is stranded is a pair insulated wire cores, every eight pairs of insulated wire cores wrap up into one group of insulated wire cores with the protective flame-retardant high temperature chromatographic band of different colours respectively, described cable core is twisted into by four groups of insulated wire cores, described protective flame-retardant high temperature chromatographic band comprises color polyester film and the polyethylene squeeze film of superposition bonding mutually, color polyester film and polyethylene squeeze film are all impregnated with one deck phosphor nitrogen combustion inhibitor, waterstop is surrounded with between sheath and cable core, sheath is low-smoke bittern-free highly fire-proof polyolefin jacket.
Wherein, between described sheath and waterstop, aluminium-plastic tape screen is provided with.
Wherein, between described sheath and aluminium-plastic tape screen, tinned copper wire woven shield is also provided with.
Wherein, described tinned copper wire woven shield is be the tinned copper braid of 85% ~ 92% by the count of the first braid and the second braid weaving.
Wherein, the ovality of described flame-proof damp-proof data cable is less than 0.3mm.
Wherein, described insulated wire cores comprises copper wire and is sheathed on the insulating sleeve with different colors outside copper wire.
Wherein, the copper wire of described copper wire to be diameter be 0.10 ~ 0.16mm.
The beneficial effect of the invention:
The flame-proof damp-proof data cable of the invention, chromatographic band for identifying insulated wire cores adopts protective flame-retardant high temperature chromatographic band, this protective flame-retardant high temperature chromatographic band color polyester film and polyethylene film squeeze film is bonded together by epobond epoxyn, and with color polyester film and polyethylene squeeze film for matrix impregnates one deck phosphor nitrogen combustion inhibitor, color polyester film increases the pull resistance of protective flame-retardant high temperature chromatographic band entirety, phosphor nitrogen combustion inhibitor has efficient flame retardant effect, and it is nontoxic, do not produce thick smoke and poison gas during burning, environmentally safe, it is a kind of environmental type efficient flame-retarding agent, protective flame-retardant high temperature chromatographic band is made to reach fire-retardant effect, coordinate low-smoke bittern-free highly fire-proof polyolefin jacket, data cable is made to have excellent fire resistance, waterstop is surrounded with between sheath and cable core, effective deadening steam, avoid data cable inner moist, data cable is made to adapt to wet environment.Aluminium-plastic tape screen, greatly improve the shield effectiveness of data cable, avoid electromagnetic interference, signal attenuation is little, coordinates highdensity tinned copper wire woven shield, improves the shield effectiveness of data cable further, ensures good transmission effect.

Embodiment
With the following Examples the invention is further described.
The flame-proof damp-proof data cable of the invention, as depicted in figs. 1 and 2, is sheath 1, tin-coated copper woven shield 2, aluminium-plastic tape screen 3 and waterstop 4 from outside to inside successively, is wrapped in cable core in waterstop 4.Wherein, sheath 1 is low-smoke bittern-free highly fire-proof polyolefin jacket, for fire protection flame retarding.Tin-coated copper woven shield 2 be preferably by the count of the first braid and the second braid weaving 85% ~ 92% tinned copper braid, to provide good shield effectiveness.
Cable core is twisted into by four groups of insulated wire cores 6, often organizes insulated wire cores 6 and comprises eight pairs of insulated wire cores 6, and protective flame-retardant high temperature chromatographic band 5 wrapping respectively by different colours forms, as shown in Figure 2.The often pair of insulated wire cores 6 then by the insulated wire cores 6 of two different colours twist combined into.The insulating sleeve 7 that insulated wire cores 6 comprises copper wire 8 and is sheathed on outside copper wire 8, insulating sleeve 7 has different colors, makes different insulated wire cores 6 have different colors.Preferably, insulating sleeve 7 is high density polyethylene (HDPE) insulating sleeve, and copper wire 8 adopts diameter to be the copper wire of 0.10 ~ 0.16mm.
