Abstract
The invention discloses a high-inflaming-retarding strong-current-interference-prevention environment-friendly railway signal cable which comprises an insulating cable core. A comprehensive protection layer, an armor layer and an outer protection layer are sequentially arranged on the periphery of the insulating cable core from inside to outside in a wrapping mode. The high-inflaming-retarding strong-current-interference-prevention environment-friendly railway signal cable is characterized in that an inner oxygen isolation layer is arranged between the comprehensive protection layer and the armor layer, and an outer oxygen isolation layer is arranged between the armor layer and the outer protection layer. The double oxygen isolation layers can effectively improve the inflaming-retarding effect of the cable, the comprehensive oxygen index of the cable is made to be over 36 and the cable can meet the requirement of over-B-level flame retarding. Meanwhile, the armor layer is made of high-magnetic-permeability materials, so that the inductance of the armor layer of the cable is increased, the shielding coefficient of the cable is lowered and the strong-current-interference-prevention performance of the cable is improved.
Description
Technical field
The present invention relates to field of cables, particularly a kind of rated voltage that is applicable to exchanges 500V or direct current 1000V and following railway signal system track circuit, row control automatics and train overspeed protection system ground and arranges etc. in equipment for transmitting the high flame retardant overcurrent proof interference environment-friendly type railway signal cable fixedly laying for railway signal or some automatics.
Background technology
Along with the electrified development of China railways, the electromagnetic radiation that the communication line in electric railway region is subject to is strengthened just day by day, in order to guarantee communication quality, in the urgent need to a kind of signal cable that can disturb stronger electrified section to use at forceful electric power; And the flame retardant effect of current signal cable is not outstanding yet.
Summary of the invention
Deficiency and the defects such as that technical problem to be solved by this invention is is poor for the overcurrent proof interference of existing signal cable, poor fire, provide a kind of as above high flame retardant overcurrent proof of problem that can solve to disturb environment-friendly type railway signal cable.
Technical problem solved by the invention can realize by the following technical solutions:
High flame retardant overcurrent proof disturbs environment-friendly type railway signal cable, comprise insulated wire cores, in described insulated wire cores periphery, be coated with successively from the inside to the outside integrated sheath, armour, outer jacket, it is characterized in that, between described integrated sheath and described armour, be provided with interior oxygen barrier layer, between described armour and described outer jacket, be provided with outer oxygen barrier layer.
In a preferred embodiment of the invention, described interior oxygen barrier layer is for extruding oxygen barrier layer.
In a preferred embodiment of the invention, described outer oxygen barrier layer is wrapped oxygen barrier layer.
In a preferred embodiment of the invention, the armour of described armour for adopting high permeability material to make.
In a preferred embodiment of the invention, described outer jacket is halogen-free and low-smoke flame-retardant polyolefin outer jacket.
In a preferred embodiment of the invention, described insulated wire cores is by some stranded the forming of insulated copper core conductor.
Owing to having adopted technical scheme as above, double-layer oxygen-isolating layer of the present invention can effectively improve the flame retardant effect of cable, makes the comprehensive oxygen index of cable more than 36, and cable reaches the above fire-retardant requirement of B level; Meanwhile, armour of the present invention adopts high permeability material to make, and has increased the inductance of cable sheath, has reduced the shielding factor of cable, has improved the overcurrent proof jamming performance of cable.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Shown in Figure 1, a kind of high flame retardant overcurrent proof disturbs environment-friendly type railway signal cable to comprise insulated wire cores 10, insulated wire cores 10 is by some stranded the forming of insulated copper core conductor 11, each insulated copper-core conductor 11 forms by some copper conductors 12 are stranded, each copper conductor 12 is coated with insulating barrier 13, and the gap between some copper conductors 12 utilizes pricks yarn 14 fillings.
In insulated wire cores 10 peripheries, be coated with successively from the inside to the outside integrated sheath 20, extrude oxygen barrier layer 30, armour 40, wrapped oxygen barrier layer 50 and outer jacket 60.Armour 40 is the armour that adopts high permeability material to make, and has increased the inductance of cable sheath, has reduced the shielding factor of cable, has improved the overcurrent proof jamming performance of cable.
Two oxygen barrier layer structures of extruding oxygen barrier layer 30 and wrapped oxygen barrier layer 50 compositions can effectively improve the flame retardant effect of cable, make the comprehensive oxygen index of cable more than 36, and cable reaches the above fire-retardant requirement of B level.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
