Description
Technical field
This utility model relates to communication technical field, is specially a kind of fire protection flame retarding brace type absorbing communication cable.
Background technology
At present, there is unreasonable structure in cable of the prior art, structure bulky, cable easily causes to be dried and causes electric leakage, obstruction signal transmits, fiber-optic signal is easily bent, transmission jitter, affect the service life of cable simultaneously, simultaneously, cable is during processing, it is required for greatly on the outer wall of conductor, be provided with external sheath layer, these external sheath layers, in traditional technology, compare under overall situation if communication cable is arranged on some vibrations, the signal transmission of cable is easily subject to interference, common cable is difficult to meet adaption demand, simultaneously in the environment of some are special, fireproofing of cable fire resistance is poor, also can often occur to be baited damaged condition by animal, therefore fire protection flame retarding brace type absorbing communication cable.
Utility model content
The purpose of this utility model is to provide a kind of fire protection flame retarding brace type absorbing communication cable, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of fire protection flame retarding brace type absorbing communication cable, its composition includes: resistance to electricity trace oversheath, it is provided with aramid fiber lapping layer one inside described resistance to electricity trace oversheath, described aramid fiber lapping layer medial wall is provided with polyethylene inner sheath, it is provided with water blocking layer inside described polyethylene inner sheath, fine cream is filled in described water blocking layer, FRP strengthening core it is enclosed with in described water blocking layer, the distributed about of described FRP strengthening core has multiple optical cable, it is provided with metal hose outside described resistance to electricity trace oversheath, aramid fiber lapping layer two it is provided with outside described metal hose, it is provided with fibrous layer outside described aramid fiber lapping layer two, PVC flame retardant sheath layer it is provided with outside described fibrous layer.
Preferably, described fire protection flame retarding brace type absorbing communication cable, the side of described optical cable is distributed multiple gasket for packing.
Preferably, described fire protection flame retarding brace type absorbing communication cable, described fibrous layer is the mixed fiber layer of extra-fine steel fiber or glass fibre.
Preferably, described fire protection flame retarding brace type absorbing communication cable, described metal hose uses flexible metal corrugated hose.
Compared with prior art, the beneficial effects of the utility model are: this construction of cable is simple and convenient to operate, Integral cable possesses fire prevention, waterproof, anti-tear stings characteristic, proper communication is can ensure that under some special environments, the insulating properties of sheath and the ability of anti-electric-mark can be improved so that the stable signal transmission of communication cable improves by resistance to electricity trace oversheath.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1, gasket for packing, 2, FRP strengthening core, 3, optical cable, 4, fine cream, 5, water blocking layer, 6, polyethylene inner sheath, 7, aramid fiber lapping layer one, 8, resistance to electricity trace oversheath, 9, metal hose, 10, aramid fiber lapping layer two, 11, fibrous layer, 12, PVC flame retardant sheath layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，A kind of technical scheme of this utility model offer: a kind of fire protection flame retarding brace type absorbing communication cable，Its composition includes: resistance to electricity trace oversheath 8，It is provided with aramid fiber lapping layer 1 inside resistance to electricity trace oversheath 8，Aramid fiber lapping layer 1 medial wall is provided with polyethylene inner sheath 6，Water blocking layer 5 it is provided with inside polyethylene inner sheath 6，Fine cream 4 is filled in water blocking layer 5，FRP strengthening core 2 it is enclosed with in water blocking layer 5，The distributed about of FRP strengthening core 2 has multiple optical cable 3，It is provided with metal hose 9 outside resistance to electricity trace oversheath 8，Aramid fiber lapping layer 2 10 it is provided with outside metal hose 9，Fibrous layer 11 it is provided with outside aramid fiber lapping layer 2 10，PVC flame retardant sheath layer 12 it is provided with outside fibrous layer 11，The side of optical cable 3 is distributed multiple gasket for packing 1，Fibrous layer 11 is the mixed fiber layer of extra-fine steel fiber or glass fibre，Metal hose 9 uses flexible metal corrugated hose.
Operation principle: the outer wall at cable is provided with resistance to electricity trace oversheath, resistance to electricity trace oversheath 8 is nonpolar polymeric material base material polyethylene (PE), this utility model resistance to electricity trace oversheath 8 reduces the content (generally below 2.6%) of the carbon black in protective cover material, add other similar uvioresistant additive simultaneously, accomplish the ability of resisting environmental stress and cracking and the anti-ultraviolet aging that both can guarantee that sheath, the insulating properties of sheath and the ability of anti-electric-mark can be improved again, the stable signal transmission making communication cable improves, simultaneously by being provided with aramid fiber lapping layer 2 10 outside PVC flame retardant sheath layer 12 and metal hose 9, it is provided with fibrous layer 11 outside aramid fiber lapping layer 2 10 and ensures fireproofing of cable, resistance to baiting property, on the premise of ensureing proper communication, more safe and reliable.
