Abstract
The utility model relates to a conduction macromolecule sheath run-through earth wire for a special line for passenger trains, which comprises an intertwisted conductor which is intertwisted by a plurality of copper wires and at least one alarming line, wherein, the alarming line is arranged at the surface of the intertwist conductor, and a conduction macromolecule sheath is arranged outside the intertwist conductor. A corrosion prevention conductive coating is coated between the outer surface of the intertwist conductor and the conduction macromolecule sheath, and the noncorrosibility of the conductor is improved. The conduction macromolecule sheath comprises an inner sheath which is firstly extruded and is arranged outside the corrosion prevention conductive coating, and an outer sheath which is secondly extruded and is arranged at the periphery of the inner sheath. The conduction macromolecule sheath is made by adopting oxidation resistant conduction polymer material, so the service life of the earth wire is prolonged. The conduction macromolecule sheath run-through earth wire has environment protection without pollution, low cost, good bending property, convenient construction, continuous alarming line, and long service life.
Description
Technical field
The utility model relates to railway art, specifically is a kind of conductive high polymer sheath run-through ground wire that is used for special line for passenger trains.
Background technology
Development along with many Lines for Passenger Transportation of railway and high-speed railway, train running speed is more and more faster, thereby automation and fail safe to the railways train operation commander are had higher requirement, requirement is laid Through ground wire along the trunk railway total length, form the integrated ground system, so that each working point earthing potential of the signalling arrangement of whole system is consistent and satisfies the backflow needs, guarantee that the system equipment security of operation is reliable and stable.
Present employed Through ground wire is the sheath copper cash, but plumbous meeting cause severe contamination to environment.And alarming line all is arranged on the inside or the centre of stranded conductor in the present Through ground wire, and maintenance construction continues very inconvenient.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of conductive high polymer sheath run-through ground wire that is used for special line for passenger trains, its environment friendly and pollution-free and easy construction.
The technical solution of the utility model is: be used for the conductive high polymer sheath run-through ground wire of special line for passenger trains, comprise by many copper cash and at least one stranded stranded conductor that forms of alarming line; Described alarming line is arranged on the surface of stranded conductor; Described stranded conductor is provided with conductive high polymer sheath outward.
Like this, alarming line is convenient to construction and is continued, and adopt conductive high polymer sheath to avoid environmental pollution, and cost is low, good bending property, is convenient to construction.
In this Through ground wire, be coated with anticorrosion conductive coating between described stranded conductor outer surface and the conductive high polymer sheath, improved the anti-corrosive properties of conductor.
In this Through ground wire, described conductive high polymer sheath comprises and is arranged on the outer protective sleeve that the internal layer sheath that anticorrosion conductive coating extrudes the outer first time and the second time that is positioned at internal layer sheath periphery extrude.Conductive high polymer sheath extrudes at twice like this, guarantees that sheath is tight, rounding, has reduced the internal stress of conductive high polymer sheath, avoids causing easy cracking because unbalanced stress is spared.
In this Through ground wire, conductive high polymer sheath adopts oxidation resistant conducting polymer composite to make, and prolongs the useful life of Through ground wire.
The beneficial effects of the utility model are: it is environment friendly and pollution-free, and antiseptic property is good, and cost is low, good bending property, the continuing of convenient construction and alarming line; Long service life.
