Abstract

The invention discloses a fireproof self-regulating cable. The fireproof self-regulating cable comprises a plurality of cable cores, a covering layer, a shield layer, an insulating layer and a PVC rubber protective sleeve. A heat insulating layer is arranged on one side of the outer side of the shield layer. A fireproof layer is arranged between the insulating layer and the PVC rubber protective sleeve. The fireproof layer is composed of a plurality of fireproof strips which are made of organic silicon mixed with mica and polyvinyl chloride. The heat insulating layer is fiberglass containing graphite particles. The fireproof self-regulating cable is widely applied to the electricity generation field, the metallurgy field, the petrochemical industry field and other fields, is especially suitable for being used in a high-temperature working environment or in sun exposure for a long term, has excellent fireproof performance and can work at the high temperature of 150 DEG C for four hours; moreover, the utilization rate of heat emitted by the cable is improved, so the fireproof self-regulating cable plays an obvious role in saving energy.

Description

A kind of fire prevention temp auto-controlled cable
Technical field
The present invention relates to field of cables, relate in particular to a kind of fire prevention temp auto-controlled cable.
Background technology
At present, along with Chinese society expanding economy, cable consumption increases rapidly, the quality requirement of cable is also constantly improved, especially for for a long time at high-temperature work environment or cruelly leak the fireproofing of cable performance using under solar radiation, the aspect such as utilance and energy-efficient performance of distribute heat requires all high especially.Only meet the requirements, be just more conducive to manufacture and the use of cable.
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 prevention temp auto-controlled cable.
The present invention takes following technical scheme to realize: a kind of fire prevention temp auto-controlled cable; it comprises some composition cable cores and the belting layer of extrusion molding outside conductor wire core; also be enclosed with successively screen, insulating barrier and PVC rubber protecting jacket outward at belting layer; a side in described screen outside is also provided with thermal insulation layer; between described insulating barrier and described PVC rubber protecting jacket, wrap up one deck fireprotection layer, described fireprotection layer is that circular circumscribed fire guard is mutually arranged and formed successively by some cross sections.
Described fire guard is made up of the organosilicon and the polyvinyl chloride that add mica.
Described thermal insulation layer is the glass fibre that contains graphite granule.
Described screen is that the annealed Al-alloy braiding of electroplating surfaces with tin forms.
The present invention has following beneficial effect in sum: this kind of cable applications is extensive, and long service life is particularly useful for for a long time at high-temperature work environment or the sudden and violent cable using under solar radiation that leaks.Not only there is good fire protecting performance, allow cable to work 4 hours under 150 DEG C of high temperature, and improve the utilance of cable distribute heat, can make cable carry out directed distribute heat, the heat orientation that cable is produced passes to heated equipment, reduce heat loss, and then reduced the loss to electric energy, played significant energy-conserving action.
Brief description of the drawings
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, core; 2, belting layer; 3, screen; 4, thermal insulation layer; 5, insulating barrier; 6, fireprotection layer; 7, PVC rubber protecting jacket.
Embodiment
The object of this invention is to provide a kind of fire prevention temp auto-controlled cable, be further described below in conjunction with accompanying drawing.
As shown in Figure 1; a kind of fire prevention temp auto-controlled cable; it comprises some composition cable cores 1 and the extrusion molding belting layer 2 outside conductor wire core 1; also be enclosed with successively screen 3, insulating barrier 5 and PVC rubber protecting jacket 7 outward at belting layer; a side in described screen 3 outsides is also provided with thermal insulation layer 4; between described insulating barrier 5 and described PVR rubber protecting jacket 7, wrap up one deck fireprotection layer 6, described fireprotection layer 6 is that circular circumscribed fire guard is mutually arranged and formed successively by some cross sections.
Described fire guard is made up of the organosilicon and the polyvinyl chloride that add mica, has good fire protecting performance, allows cable to work 4 hours under 150 DEG C of high temperature.
The annealed Al-alloy braiding that described screen 3 is electroplating surfaces with tin forms.
The glass fibre of described thermal insulation layer 4 for containing graphite granule, improve the utilance of cable distribute heat, can make cable carry out directed distribute heat, the heat orientation that cable is produced passes to heated equipment, reduce heat loss, and then reduced the loss to electric energy, play significant energy-conserving action.
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.
