Abstract
The utility model discloses a high-temperature-resistant fireproof cable. The high-temperature-resistant fireproof cable comprises a conducting wire core, an insulation layer and an outer sheath; the insulation layer coats the conducting wire core; a reinforcement layer, a fireproof layer and a glass fiber layer are sequentially arranged between the insulation layer and the outer sheath from interior to exterior; and the insulation layer, the reinforcement layer, the fireproof layer, the glass fiber layer and the outer sheath layer are adhered through adhesives. The high-temperature-resistant fireproof cable has a simple structure and novel design, and can be suitable for signal monitoring and cable transmission of high-temperature environment, particularly control of a protection circuit of a fire control and security system, and a transmission line of power; and the impact resistance effect is improved by the reinforcement layer, the fireproof layer effectively exerts a fireproof effect, and the high temperature resistance can be improved by the glass fiber layer, the increasing of the thickness of the fluoroplastic and silicon rubber insulation layer can be avoided, the cost is controlled, and the production requirement and actual requirements are met.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of fire resistant cable.
Background technology
The cable that in some hot environments, uses like power plant, steel mill etc. not only need bear higher ambient temperature, and especially need bear core conductor temperatures higher as about 200 ℃.Common polyvinyl chloride ((PVC) insulation and jacketed cable, because of the PVC non-refractory, thereby the above-mentioned instructions for use of incompatibility; Fluoroplastics, silicon rubber insulation and jacketed cable, its heat resistance meets the demands, but the oversheath resistance to wear is relatively poor, when cable is laid, very easily wear and tear, and then influence insulation property, and cost is higher relatively; Directly adopt fluoroplastics, silicon rubber to make insulating barrier, the PVC sheath that the external application resistance to wear is good, then poor because of the PVC heat-resisting quantity; Need to strengthen fluoroplastics, silicon rubber insulation layer thickness; To reduce the outer temperature of insulating barrier, so not only cause cable cost to rise, and cable size is with overstriking.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of fire resistant cable.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of fire resistant cable; Comprise conductor wire core, insulating barrier and oversheath; Insulating barrier coated with conductive core is provided with reinforced layer, fireprotection layer and glass layer from inside to outside successively between insulating barrier and the oversheath, bonding through viscose glue between insulating barrier, reinforced layer, fireprotection layer, glass layer and the outer jacket.
As preferably, be filled with reinforcement in the reinforced layer, reinforcement evenly distributes along the outer wall of conductor wire core.
As preferably, oversheath is the PVC layer.
As preferably, insulating barrier is that rubber tube and its thickness are 1.5mm.
Compared with prior art, the advantage of the utility model is: simple in structure, modern design can be applicable to the signal monitoring and the cable transmission of hot environment.Be particularly useful for the control in fire-fighting and security system protection loop and the transmission line of power; Reinforced layer has improved the resistance effect; Fireprotection layer can effectively play flameproof effect, and glass layer can avoid the use of and strengthen fluoroplastics, silicon rubber insulation layer thickness so that heat-resisting quantity improves; Make that also cost is under control, satisfy the needs of producing with actual.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, conductor wire core; 2, insulating barrier; 31, reinforced layer; 32, reinforcement; 4, fireprotection layer; 5, glass layer; 6, oversheath.
Embodiment
To combine accompanying drawing that the utility model is described further below.
A kind of execution mode as the utility model; Consult Fig. 1; The utility model comprises conductor wire core 1, insulating barrier 2 and oversheath 6; Insulating barrier 2 coated with conductive cores 1 are provided with reinforced layer 31, fireprotection layer 4 and glass layer 5 from inside to outside successively between insulating barrier 2 and the oversheath 6, bonding through viscose glue between insulating barrier 2, reinforced layer 31, fireprotection layer 4, glass layer 5 and the outer jacket.Be filled with reinforcement 32 in the reinforced layer 31, reinforcement 32 evenly distributes along the outer wall of conductor wire core 1.Oversheath 6 is the PVC layer.Insulating barrier 2 is that rubber tube and its thickness are 1.5mm.
The utility model is simple in structure; Modern design, reinforced layer 31 has improved the resistance effect, and fireprotection layer 4 can effectively play flameproof effect; Glass layer 5 can be so that heat-resisting quantity improves; Avoid the use of and strengthen fluoroplastics, silicone rubber insulation layer 2 thickness, make that also cost is under control, satisfy the needs of producing with actual.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation in spirit that does not break away from the utility model or the scope in other embodiments among this paper.Therefore, the utility model will can not be limited to these embodiment shown in this paper, but will accord with principle disclosed herein and features of novelty the wideest corresponding to scope.
