The utility model discloses a super high-temperature-resistant flexible fireproof power cable, which comprises several conductors, and the outer parts of the several conductors are successively wrapped with an insulating layer composed of polytetrafluoroethylene film wrapping, and a layer is arranged between two layers of calcined mica tapes. The refractory layer composed of polyetheretherketone resin tapes is overlapped and wrapped. The overlapping rate of the wrap is not less than 45%. Several conductors wrapped in the refractory layer are twisted into bundles to form a cable core. The overlapping rate of wrapping is not less than 55%. The fireproof layer is wrapped with an inner sheath layer and an outer sheath layer in turn. There are several waist-shaped elastic ropes between the inner sheath layer and the outer sheath layer. The utility model adopts a layer of polyether ether ketone resin tape overlapping and wrapping to form a fire-resistant layer between two layers of calcined mica tapes. There is a waist-shaped elastic rope between the inner and outer sheath layers, which improves the structural strength of the cable and prolongs the service life of the cable.
Description
Technical field:
The utility model relates to lv power cable, relates in particular to a kind of thermostable fire resistant flexible power cable.
Background technology:
Safe fire electricity line is the important development direction of modern safety electric energy drive technology; In recent years; There is very big development in the China that is applied in of various flame resistant cables, low-smoke halogen-free cable, and has obtained good effect, and a large amount of low-smoke bittern-free highly fire-proof electric wires has just been adopted in the construction of Guangzhou Underground passage; We can say that safe fire electricity line has spread all over each mainly the crowd is dense the district.
But above-mentioned said cable; Along with industrial height is rapid; Like the popularization of bullet train, the construction of offshore oil platform; The environment for use of cable is more and more abominable, and fire prevention temperature grade is low, the cable additional materials reaches the restriction of materials used more and can't be used in above-mentioned occasion in a large number because receive for traditional fireproof cable.
For this reason,, designed novel, unique thermostable flexible fire-proof cable, fire resistance rating has been promoted to more than 950 ℃, satisfied the cable fire-proof performance demands simultaneously from structure and technology mode through analysis to the used cable of this type of occasion.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of thermostable fire resistant flexible power cable, has solved in the high temperature occasion existing cable deadly defect of continuous service for a long time.
The technical scheme of the utility model is following:
Thermostable fire resistant flexible power cable; Comprise several conductors; It is characterized in that: described several conductors are enclosed with the flame retardant coating that is provided with the overlapping wrapped formation of one deck polyether-ether-ketone resin band between the insulating barrier of the wrapped formation of poly tetrafluoroethylene, the two-layer calcining mica tape respectively outward successively, and wrapped Duplication is not less than 45%, and the mutual stranded bunchy of several conductors of parcel flame retardant coating constitutes cable core; Cable core is surrounded with the fireprotection layer that the calcining mica tape constitutes outward; Wrapped Duplication is not less than 55%, and fireprotection layer is enclosed with inner restrictive coating, external sheath layer outward successively, is provided with the elastic threads of several waist shapes between sheath and the outer jacket.
Described thermostable fire resistant flexible power cable is characterized in that: described several conductors adopt the tinned copper wire flexible conductor.
The beneficial effect of the utility model is:
The utility model adopts and is provided with the overlapping wrapped formation flame retardant coating of one deck polyether-ether-ketone resin band between the two-layer calcining mica tape; Cable core is wrapped with fireprotection layer; Duplication increases gradually, has improved fireproofing of cable, fire resistance, is provided with the elastic threads of waist shape between the interior external sheath layer; Improve the structural strength of cable, prolonged the useful life of cable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
