Abstract
The utility model relates to a novel low-smoke halogen-free fire resistant railway digital traffic signal cable comprising a conductor, an insulating layer, a shielding layer and a protective sleeve. The novel low-smoke halogen-free fire resistant railway traffic digital signal cable is characterized in that the outer surface of the conductor is provided with the insulating layer; a wire group of two conductors provided with the insulating layers is sequentially provided with a wrapping layer and an inner shielding layer so as to form a wire group cable; and a cable core formed by stranding of a plurality of wire group cables is sequentially provided with a water-blocking tape layer, an outer shielding layer, an oxygen barrier layer, an armor layer, a protective sleeve cracking resistant layer and a protective layer. The novel low-smoke halogen-free fire resistant railway traffic digital signal cable has the advantages of good shielding effect, high signal transmission capacity, long service life, fire resistance, water resistance and good sun-proof performance.
Description
Technical field
The utility model belongs to technical field of communication cables, particularly relates to a kind of novel low-smoke non-halogen flame-retardant track traffic digital signal cable.
Background technology
At present, along with improving constantly of China's development of economic construction and transport information degree, greatly developing information technology and extensive use electronic computer has been the modern important symbol of track traffic.Communication cable is the important component part in the rail traffic signal system, fast development along with China's track traffic, the environment of cabling is also more and more diversified, thereby the every performance requirement of track traffic with communication cable also improved constantly, and digital signal cable of the prior art does not all have the performance of waterproof and antiultraviolet.So, be badly in need of a kind of environmental protection of exploitation, waterproof, fire-retardant and the track traffic digital signal cable of performance such as antiultraviolet arranged.
Summary of the invention
The utility model provides the novel low-smoke non-halogen flame-retardant track traffic digital signal cable of a kind of environmental protection, waterproof, antiultraviolet, fire-retardant and long service life for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of novel low-smoke non-halogen flame-retardant track traffic digital signal cable, comprise conductor, insulating barrier, screen and sheath, it is characterized in that: the outer surface of described conductor is provided with insulating barrier, on the line group of two conductors that are provided with insulating barrier, set gradually belting layer and internal shield, constitute line group cable with this, be provided with water blocking tape layer, outer shielding layer, oxygen barrier layer, armour, protective jacket cracking layer and restrictive coating on the stranded cable core that forms of several line group cables successively.
The utility model can also adopt following technical scheme:
Gap location between the line group of the described conductor that is provided with insulating barrier and the gap location between the line group cable are equipped with filler.
Described internal shield adopts metal wire knitted to form.
Described outer shielding layer is an aluminium-plastic tape.
Described insulating barrier, oxygen barrier layer and restrictive coating are made by the halogen-free polyolefin material.
Described line group cable is the 2-61 root.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, be that cable comprises inside and outside two screens, and internal shield is formed by metal wire knitted, outer shielding layer is an aluminium-plastic tape, not only increase shield effectiveness, improve cable and carry the ability of digital signal, can also improve the water-resisting ability of cable; Insulating barrier, oxygen barrier layer and restrictive coating are made by the halogen-free polyolefin material, except that the fire retardancy that strengthens cable, also make cable have the ability of antiultraviolet, can prevent effectively that the cable cable is because of the sheath cracking that is exposed to the sun in the sun, prolong the useful life of cable, and good environmental protection; Be provided with protective jacket cracking layer between armour and the restrictive coating, can reduce the slit that forms between armour and the restrictive coating, thereby reduce the interior shear stress of sheath, prevent the sheath cracking.
