Abstract
The invention discloses a fireproof cable resistant to high temperature. The fireproof cable comprises a cable core, a wrapping tape layer, a heat insulation layer and a PVC elastomer protection jacket. A fireproof layer is arranged on one side outside the heat insulation layer and composed of a plurality of fireproof belts with the cross sections being round. The circumferences of the fireproof belts are tangent. The fireproof belts are made of chlorinated rubber comprising aluminium silicate and paraffin. The heat insulation layer is made of glass fibers comprising mica. The fireproof cable is widely applied to the fields of electricity generation, metallurgy, chemical engineering petroleum and the like and especially suitable for being exposed in solar radiation for a long time and used in the high-temperature work environment, and is excellent in resistance to high temperature and fireproof performance. The maximum allowable work environment temperature of the fireproof cable is 105 DEG C, the fireproof cable can be used in the high-temperature environment of 200 DEG C for 2.5 hours, and the safety of the cable is greatly improved.
Description
Technical field
The invention belongs to field of cables, relate in particular to a kind of fire resistant cable.
Background technology
At present, along with socioeconomic development, cable consumption increases rapidly, and the quality requirement of cable is also constantly improved.For example cruelly leak for a long time the cable using under solar radiation and in high-temperature work environment, fireproofing of cable resistance to elevated temperatures is proposed to higher requirement.Once fireproofing of cable resistance to elevated temperatures just may cause very big hidden danger not.Therefore, only meet the requirements, could the better fail safe that ensures these field inner cables.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of fire resistant cable.
The present invention takes following technical scheme to realize: a kind of fire resistant cable; it comprises core, belting layer, thermal insulation layer and PVC elastomer protective sleeve; a side in described thermal insulation layer outside is also provided with fireprotection layer; described fireprotection layer is that circular fire guard forms by several cross sections; between described fire guard is mutual, circumference is tangent; described fire guard material is for containing alumina silicate, chlorination of paraffins rubber, and described insulating layer material is micaceous glass fibre.
Described core is to arrange radially centered by filler, and the periphery of two adjacent cores contacts with each other.
Described filler is silicon rubber.
The present invention has following beneficial effect in sum: the present invention is widely used in the fields such as generating, metallurgy, chemical petroleum, is particularly useful for cruelly leaking for a long time the cable using under solar radiation and in high-temperature work environment.This utility model has good resistance to elevated temperatures and stronger fire protecting performance, and allowing operational environment maximum temperature is 105 ℃, allows to use 2.5 hours in 200 ℃ of hot environments, has greatly improved the fail safe of cable.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, filler; 2, core; 3, belting layer; 4, thermal insulation layer; 5, fireprotection layer; 6, PVC elastomer protective sleeve.
Embodiment
The object of this invention is to provide a kind of fire resistant cable, be further described below in conjunction with accompanying drawing.
As shown in Figure 1; a kind of fire resistant cable; it comprises core 2, belting layer 3, thermal insulation layer 4 and PVC elastomer protective sleeve 6; a side in described thermal insulation layer 4 outsides is also provided with fireprotection layer 5; described thermal insulation layer 4 materials are micaceous glass fibre, have greatly strengthened the thermal and insulating performance of cable.
Described fireprotection layer 5 is that circular fire guard forms by several cross sections, between described fire guard is mutual, circumference is tangent, described fire guard material, for containing alumina silicate, chlorination of paraffins rubber, can effectively prevent the destruction of hot environment to cable, improves significantly fireproofing of cable performance.
Described core 2 is to arrange radially centered by filler 1, and the periphery of two adjacent cores 2 contacts with each other.
Described filler 1 is silicon rubber.
It is 105 ℃ that this cable allows operational environment maximum temperature; Allow to use 2.5 hours in 200 ℃ of hot environments, greatly improved the fail safe of cable.
The above is embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
