A cable for rail transit relates to the technical field of cable structures. The cable for rail transit of the utility model includes three sets of wire cores, and on the outside of the three sets of wire cores, a water-blocking tape wrapping layer, an aluminum-plastic composite tape longitudinal wrapping layer, a halogen-free polyolefin inner sheath, a copper tape armoring layer, The first flame-retardant tape layer and the environmental protection polymer outer sheath; a filling layer is set between the three sets of wire cores and the water-blocking tape wrapping layer; An insulating layer and a second flame-retardant tape layer are sequentially arranged on the outer side of the stranded conductor. The utility model has the advantages of simple and reasonable structure, long service life and high safety, and is suitable for cables used in modern urban rail transit.
Description
Technical field
The utility model relates to the technical field of the construction of cable, particularly a kind of cable for rail transit.
Background technology
Along with the high speed development of urban rail transit in China cause, the demand of cable for rail transit is also in continuous increase.According to data, in the coming years, China will have more than 20 city plan to build subway and light rail, always run mileage to track traffic in 2015 and will reach more than the 2400km, and newly-increased rail intersection road, 2011-2015 years cities length compound growth rate is 21%.The raising of track traffic technical equipment, to having proposed new problem for its supporting electric wire performance, structure, the cable that particularly adapts to the modern city track traffic is particularly important.
Summary of the invention
The utility model is for overcoming the deficiency of existing cable technology, a kind of cable for rail transit with excellent electrical properties, fire resistance, water resistance and physical and mechanical properties being provided.
The utility model comprises three groups of cores, sets gradually waterstop lapping layer, aluminum plastic composite belt longitudinal covering, halogen-free polyolefin sheath, copper strips armour, the first inhibiting tape belting layer and environmental protective polymer outer jacket in described three groups of cores outside; Between described three groups of cores and waterstop lapping layer, packed layer is set; Described every group of core comprises respectively copper wire bundle strand conductor, sets gradually insulating barrier and the second inhibiting tape belting layer in the described copper wire bundle strand conductor outside.
The utility model is simple and reasonable, and long service life is safe, adapts to the modern city cable for rail transit.
