Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of effectively increase railway power supply ability, and the railway tunnel power consumption power cable of available protecting cable internal structure.
The present invention is a kind of railway tunnel power consumption power cable, comprise outer jacket, and be arranged on the layer of resist of outer jacket inside, and be arranged on the protective layer of layer of resist inside, and be arranged on the flame-retardant layer of protective layer inside, and be arranged on the tensile layer of flame-retardant layer inside, and be arranged on the fibrage of tensile layer inside, and be arranged on the rubber layer of fibrage inside, and be arranged on conductor and the wire of rubber layer inside, described wire is aramid fiber rope, and wire is positioned at the central authorities of rubber layer, described conductor is provided with more than two, described fibrage is glass fibre, and tensile layer inside is provided with plural fibrage.
As preferably, described rubber layer is fireproof silica gel, effectively avoids conductor to use for a long time and produces heat and cause dieseling.
As preferably, described flame-retardant layer is neoprene, can effectively prevent this cable from burning because of external environment on fire.
As preferably, described protective layer inside is provided with glue powder polyphenyl particle, and the central authorities of protective layer are also provided with steel wire, allows protective layer effectively can protect internal structure, avoids causing damage because external world's extruding.
As preferably, described layer of resist inside is provided with polytetrafluoroethylene, the effective internal corrosion increasing this cable, the effective useful life increasing this cable.
The invention has the beneficial effects as follows: because fibrage is provided with two or more, each fibrage inside is provided with rubber layer, and each rubber layer inside is provided with plural conductor, the electric power of railway is allowed enough to be carried by conductor, the effective power supply ability to transmit electricity increasing this cable; And the setting of wire, rubber layer, fibrage, tensile layer, flame-retardant layer, protective layer, layer of resist and outer jacket can effectively be protected this cable; cable is effectively avoided to occur spontaneous combustion on fire, corrosion and ageing in use or cause damage because of external environment; increase the useful life of this cable greatly, extend the service time of this cable.
Accompanying drawing explanation
