Description
Technical field
The utility model patent relates to cable technology field, particularly, relates generally to the composite braided shielded flexible cable of a kind of urban track traffic fire-resistant moving control of LSOH anti-flaming.
Background technology
Urban track traffic is the major measure that traffic environment is improved in current international big city, and due to the particularity of track traffic, security, reliability requirement to power system are high. And subway, light rail cable lay circumstance complication, prior art products often can not meet the various harsh requirement of laying simultaneously; Urban light rail subway mostly is densely populated underground by the environment for use of cable, once breaking out of fire, the environment of underground sealed brings very large difficulty to personnel escape and fire-fighting work. Therefore fire resistance is had relatively high expectations, fire resistance will meet the requirement of A level in GB/T18380.3. Meanwhile, when burning, the release of smog and toxic gas can hinder firemanic carrying out, and sour gas all can damage people and equipment, and during therefore to burning, the burst size of smog and toxic gas also has higher requirement; Urban light rail subway is the effect due to environment and meteorologic factor with cable, likely the long period is laid under moist environment cable, hydrone likely immerses cable, invade cable inside, be insulated absorption and absorb, cause the decline of electric property, can cause oxidation, the corrosion of conductor, not only affect the electrical property of cable, and abnormal broken line accident can occur when serious, cable will have water-proof function; Urban light rail subway is laid in underground for a long time with cable, be easily subject to the attack of toy (as muroid, ant class), affects the performance of cable, and cable should have termite-resistant rodent-resistant function; If urban light rail subway is not to use in subway with cable cable, but be laid in elevated railway, so just may stand for a long time the test of solar radiation and various meteorological conditions, the sheath of cable is for a long time by solar radiation, easily there is color fading, the mechanical and physical performance even phenomenon such as cracking that declines, cable should have anti-ultraviolet function; Urban light rail subway cable laying limited space, one side requires direct current cables lightweight, flexible, radius of turn is little. On the other hand, the cable type that lays in roughing-in is many, quantity is many, need the outside diameter of cable little, easily lay; Urban light rail subway is except a large amount of power cable of needs, also need to 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 measurement cable are processed separately, are laid respectively, this not only brings difficulty to construction, has also increased use and construction cost; And because the wire core diameter of control, signal, protection and measurement cable is less, tensile strength is lower, easily abrades or break in laid processes.
