Description
Technical field
Patent of the present invention relates to field of cable technology, specifically, relates generally to the fire-resistant dynamic control composite cable of a kind of urban track traffic LSOH anti-flaming.
Background technology
Urban track traffic is the major measure that traffic environment is improved in current international big city, due to the particularity of track traffic, high to the fail safe of electric power system, reliability requirement.And subway, light rail cable lay circumstance complication, prior art products often can not meet the various rigors laid simultaneously; The environment for use of urban light rail subway cable mostly is densely populated underground, once breaking out of fire, the environment of underground sealed brings very large difficulty to personnel escape and fire-fighting work.Therefore require higher to fire resistance, fire resistance will meet the requirement of A level in GB/T18380.3.Meanwhile, during burning, the release of smog and toxic gas can hinder firemanic carrying out, and sour gas all can damage people and equipment, therefore also has higher requirement to the burst size of smog during burning and toxic gas; Urban light rail subway cable is due to the effect of environment and meteorologic factor, cable likely lay in a humidity environment by the long period, hydrone likely immerses cable, invade cable inside, absorbed by insulation absorption, cause the decline of electric property, the oxidation of conductor, corrosion can be caused, not only affect the electrical property of cable, and time serious, abnormal broken line accident can occur, cable will have water-proof function; Urban light rail subway cable is laid in underground for a long time, and be easily subject to the attack of toy (as muroid, ant class), affect the performance of cable, cable should have termite-resistant rodent-resistant function; If urban light rail subway cable cable is not use in subway, but be laid in elevated railway, so just may stand the test of solar radiation and various meteorological condition for a long time, the sheath of cable is for a long time by solar radiation, easily there is color fading, mechanical and physical performance declines the even phenomenon such as cracking, and cable should have anti-ultraviolet function; Urban light rail subway cable laying limited space, requires direct current cables lightweight on the one hand, flexible, radius of turn is little.On the other hand, the cable type laid in roughing-in is many, quantity is many, need the outside diameter of cable little, easily lay; Urban light rail subway is except needing a large amount of power cables, also need use a large amount of control, signal, protection and measure cable, prior art is owing to considering the factor of electric interfering field, often power cable and control, signal, protection and measure cable and process separately, lay respectively, this not only brings difficulty to construction, too increases use and construction cost; And due to control, signal, protection and to measure the wire core diameter of cable less, tensile strength is lower, easily abrades or break in laid processes.
Summary of the invention
The object of this invention is to provide and a kind of there is higher insulation property, fire-retardant A level, low smoke and zero halogen, fire-resistant, waterproof, termite-resistant rodent-resistant, antiultraviolet, anti-electric jamming, good bending property, compact conformation, and play the fire-resistant dynamic control composite cable of urban track traffic LSOH anti-flaming of electric energy transmitting and control, signal, protection and measurement simultaneously.
The fire-resistant dynamic control composite cable of a kind of urban track traffic LSOH anti-flaming of the present invention, comprises insulation DC electric cable cable core and at least two control conductor.Described control conductor comprises control conductor conductor, control conductor insulation, and control conductor concentric stranding forms control line sandwich layer outward at insulation DC electric cable cable core; Described insulation DC electric cable cable core comprises insulation DC electric cable conductor, the insulation DC electric cable insulation extruded, the first fire-resistant inner restrictive coating of extruding from inside to outside successively; Described control line sandwich layer comprise successively from inside to outside outward the first wrapped inhibiting tape, vertical bag aluminium-plastic tape, extrude the second fire-resistant inner restrictive coating, wrapped copper strips armouring, the second wrapped inhibiting tape, the external sheath layer that extrudes.
Further improvement, is filled with flame-retardant gasket for packing between described control conductor.
