Description

A kind of fire proof power cable

Technical field

The utility model relates to field of cables more particularly to a kind of fire proof power cables.

Background technique

With being constantly progressive for social development, requirement of the people to security protection is continuously improved.In fire-resisting cable field, people To fireproof power cable, continued power ability also has increasingly higher demands, the insulating properties of fireproof power cable in a fire Continued power ability in its fire can be had an important influence.

Utility model content

The purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of fire proof power cable.

The purpose of this utility model can be realized by following scheme: a kind of fire proof power cable, including cable core, described Be successively arranged on the outside of cable core from the inside to the outside wrapping layer, shielded layer, external insulation layer, anti-flaming thermal-insulation layer, wearing layer, steel wire armor layer with And protective layer, the cable core inside are equipped with multiple lock chambers, and a conducting wire is equipped in each lock chamber, the conducting wire includes being located at The conductor at middle part, the inner insulating layer being coated on outside conductor and the shielded tube being wrapped in outside inner insulating layer；The fixation It is intracavitary to be filled with fire proofing.

Further, the material of the inner insulating layer is ceramic silicon rubber.

Further, the shielded layer is coated using metallo-plastic composite band.

Further, the material of the external insulation layer is one of polyimide insulative paint or half-mature polytetrafluoroethylene (PTFE).

Further, the material of the wearing layer is that polyfluorinated ethylene or TPE one of work as.

The beneficial effects of the utility model are: cable core is arranged in anti-flaming thermal-insulation layer, external heat can be effectively prevent to pass It is handed to cable core, is filled with fire proofing in cable core, the heat that cable core work can be made to generate also is not easy to be transferred to Exterior cable, improves The flame retardant property of cable；Lock chamber is equipped in cable core ensure that the structural stability of cable core, effectively prevent the mutual shadow of conducting wire It rings, improves the fire resistance of cable.The utility model has excellent fire-retardancy, and security performance is high, and at low cost, makes work Skill is simple.

Detailed description of the invention

Fig. 1 is the structural schematic diagram in the utility model.

In figure: 1- cable core, 11- lock chamber, 12- conductor, 13- inner insulating layer, 14- shielded tube, 15- fire proofing, 2- Wrapping layer, 3- shielded layer, 4- external insulation layer, 5- anti-flaming thermal-insulation layer, 6- wearing layer, 7- steel wire armor layer, 8- protective layer.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work All other embodiment obtained, fall within the protection scope of the utility model.

According to Fig. 1: a kind of fire proof power cable, including cable core 1,1 outside of cable core are successively arranged wrapped from the inside to the outside Layer 2, shielded layer 3, external insulation layer 4, anti-flaming thermal-insulation layer 5, wearing layer 6, steel wire armor layer 7 and protective layer 8, the shielded layer 3 It is coated using metallo-plastic composite band；The material of the external insulation layer 4 is polyimide insulative paint or half-mature polytetrafluoroethyl-ne One of alkene；The material of the wearing layer 6 is that polyfluorinated ethylene or TPE one of work as；It is equipped with inside the cable core 1 multiple Lock chamber 11, each lock chamber 11 is interior to be equipped with a conducting wire, and the conducting wire includes the conductor 12 for being located at middle part, is coated on conductor 12 External inner insulating layer 13 and the shielded tube 14 being wrapped in outside inner insulating layer 13；The material of the inner insulating layer 13 is pottery Porcelain silicon rubber；Fire proofing 15 is filled in the lock chamber.Cable core 1 described in the utility model is arranged in anti-flaming thermal-insulation layer 5, External heat can be effectively prevent to be transferred to cable core 1, be filled with fire proofing 15 in cable core 1, the heat that the work of cable core 1 can be made to generate Amount is also not easy to be transferred to Exterior cable, improves the flame retardant property of cable；Lock chamber 11 is equipped in cable core 1 ensure that cable core 1 Structural stability, effectively prevent conducting wire to influence each other, improve the fire resistance of cable.The utility model has excellent flame retardancy Can, security performance is high, and at low cost, and manufacture craft is simple.
