Abstract
The utility model discloses a there is not steamed fire -retardant bearing cable, the low voltage cable used for the rail transit comprises a plurality of wire cores, many sinle silks merge bindes into a cable, and every sinle silk includes conductor and the insulating layer of parcel outside the conductor, the cross -section of every sinle silk is fan -shaped, and many sinle silks are closely arranged and are formed ring shape, and a parcel has or not the steel cable follow ring center of steamed insulating layer to pass, the outer parcel of cable has an insulating sheath, has the aluminium foil layer at insulating sheath's outer parcel, and outer parcel has the dry powder layer on the aluminium foil layer, and it does not have steamed layer to set up outside the dry powder layer. The utility model discloses a there is not steamed fire -retardant bearing cable adopts many sinle silks to combine to form ring shape to the structure of steel cable is lived to the parcel, makes bearing capacity stronger, and has set up the aluminium foil layer, and is little to the signal intensities of light current, has increased the dry powder layer in addition, has improved fire prevention fire behaviour.
Description
Technical field
This utility model relates to a kind of halogen-free flameproof bearing cable.
Background technology
Generally, flame retardant cable on the market, adds the halogenide containing halogen and metal-oxide in its sheath material, evaluates from fire-retardant angle, this is fabulous method, but, owing to these materials containing halogenide, discharge substantial amounts of smog and hydrogen halide when burning, so, low visibility during fire, safe escape and fire-fighting to personnel bring the biggest obstruction, and people dies of asphyxiation for toxic gas the most more.Additionally, after hydrogen halide once reacts with the water in air, i.e. generate " halogenation hydracid ", heavy corrosion instrument and equipment, building cause " secondary disaster ".
It addition, the cross section of existing multicore cable is circle, this makes multicore cable diameter after completing relatively thick, uses heavier, and meanwhile, when cable load-bearing, core is easily deformed.
Or, during house ornamentation hydropower installation at ordinary times, forceful electric power needs at forceful electric power outer layer covers tinfoil with the intersection of light current, not affect the signal transmission of light current.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of halogen-free flameproof bearing cable, it can with the flame-retarding characteristic of cable, and nontoxic smokelessly.
For solving above-mentioned technical problem, the technical solution of this utility model a kind of halogen-free flameproof bearing cable is:
Including many cores, described many cores merging is bundled into a cable, the insulating barrier that every core includes conductor and is wrapped in outside conductor, and the cross section of described every core is fan-shaped, many core close-packed arrays form annular, and a wirerope being enclosed with Halogen insulating barrier passes from circle ring center；The outer layer covers of described cable has insulating sheath, and the outer layer covers at insulating sheath has tinfoil layer, is wrapped with dry powder layer at tinfoil layer, arranges Halogen layer outside dry powder layer.
Described Halogen layer appearance is coated with reflecting coating.
Being provided with conducting strip between described adjacent both threads core, conducting strip is provided with heat-conductive coating, and described conducting strip two ends are connected to be on the fin outside cable.
Integrally formed with anti-torsion skeleton in described Halogen layer, described anti-torsion skeleton includes the many parallel steel wires along wirerope axial distribution, is connected by multiple anti-torsion steel rings along the distribution of wirerope axially spaced-apart between many steel wires.
What this utility model can reach has the technical effect that
Compared with prior art, halogen-free flameproof bearing cable of the present utility model, many cores merging define a cirque structure, place wirerope in circle ring center, and the outer layer at annulus includes insulating sheath, tinfoil layer and Halogen layer successively, wirerope plays load-bearing effect, meanwhile, annulus contacts for arcuate surface between wirerope so that cable of the present utility model is more firm, bearing capacity is bigger, and core is unlikely to deform；
Compared with prior art, halogen-free flameproof bearing cable of the present utility model, add tinfoil layer, when crossing with light current, it is not necessary to additionally wrap up tinfoil；
Compared with prior art, halogen-free flameproof bearing cable of the present utility model, add dry powder layer, improve fire retardant performance；
Compared with prior art, halogen-free flameproof bearing cable of the present utility model, due to the fitting tight between core, this causes radiating effect the best, is provided with conducting strip between adjacent both threads core, and the fin outside conducting strip connection, this improves radiating effect.
