Description
Technical field
The utility model relates to construction of cable technical field, is specially a kind of multi-shielding of resistance to daylight Halogen signal cable.
Background technology
Communication equipment occupies very important position in whole industrial system, its fine or not direct relation the quality of industrial product quality, because a lot of operation requirements are inputted in process cable transmission to machine by control panel, if working it out certainly, scraps that product of cable poor signal.Nowadays industrial circle is also more and more wider, and the project of exploitation is also more and more high-end, as wind energy, and solar energy etc.The cable of some areas must be exposed on earth's surface, make to require for heat-resisting, the sun-proof of cable, but existing signal cable shines long-time photograph, and wire rod easily breaks; Under high-temperature condition, flame retardant rating can not meet the requirement of field of employment, and need to provide a kind of is the cable of being convenient to installation of heat-resisting sun-proof again for this reason.
Summary of the invention
For the problems referred to above, the utility model provides a kind of multi-shielding of resistance to daylight Halogen signal cable, and it has the advantages that softness is good, antifatigue anti-electromagnetic interference capability is strong, can meet the demand of more severe use installation site.
A kind of multi-shielding of resistance to daylight Halogen signal cable, its technical scheme is such: its from outer in the cross-sectional structure that is arranged in order be circular sheath, braid, stranding, it is characterized in that: the outer ring surface of described stranding includes double-deck aluminium foil wheat and draws screen, described braid specifically comprises internal layer braid, middle part restrictive coating, outer braid layer three-decker, the outer field aluminium foil wheat of described stranding draws the outer ring surface of screen to be close to the inner ring surface of described internal layer braid, and the inner ring surface of described sheath is close to the outer ring surface of described outer braid layer.Described internal layer braid, outer braid layer are specially zinc-plated soft copper wire material and form, and described sheath, middle part restrictive coating specifically adopt modified thermoplastic elastomer material to make.
It is further characterized in that:
The aluminium foil wheat of the internal layer of described stranding is drawn in the cavity of screen and comprises four groups of separate signal line group, every signal line group comprises two holding wires, lapping layer, the inner core of every holding wire is wrapped with insulating barrier, after two holding wires with insulating barrier on the same group form integral body, is enclosed with lapping layer;
Four groups of signal line group are arranged and are formed foursquare four summits, and mutual close contact between the lapping layer of adjacent described signal line group;
The material of the inner core of described holding wire is specially the zinc-plated soft copper wire of annealing, and it not only avoids copper wire oxidation, has more improved the flexibility of wire rod, has promoted the torsional bending performance of wire rod;
The insulating barrier of described holding wire adopts modified polyolefine material to be made, its have advantages of soft, dielectric constant is low, good stability.
Adopt after structure of the present utility model, because the outer end anchor ring of stranding is furnished with respectively internal layer braid, middle part restrictive coating, outer braid layer, sheath, and the outer ring surface of stranding includes double-deck aluminium foil wheat and draws screen, make the inner core of holding wire of the inside of stranding at least comprise six layers of structure apart from outer end, its shielding is good, and the outer ring surface of stranding includes double-deck aluminium foil wheat and draws screen, internal layer braid, outer braid layer is specially zinc-plated soft copper wire material and forms, described sheath, middle part restrictive coating specifically adopts modified thermoplastic elastomer material to make, can meet the resistance to day optical tests of 720h, wherein aluminium foil wheat is drawn screen, zinc-plated soft copper wire material, modified thermoplastic elastomer material is all not halogen-containing, and its performance is soft, make structurally flexible performance good, good flame resistance, to sum up, it has the advantages that softness is good, antifatigue anti-electromagnetic interference capability is strong, can meet the demand of more severe use installation site.
