Abstract
The utility model discloses a ceramic fireproof cable, so as to solve the problem that the existing fireproof cable is comparatively poor in fireproof effects. The technical scheme adopted is that the ceramic fireproof cable comprises an outer sheath and a cable arranged inside the outer sheath; the cable comprises metal conductors and ceramic insulation layers; and the ceramic insulation layers are located on the periphery of the metal conductors. The ceramic fireproof cable is characterized in that a metal protection layer is arranged inside the outer sheath; a ceramic fireproof isolation layer is arranged inside the metal protection layer; the cable is located inside the fireproof isolation layer; and a filling material is filled outside the cable and inside the fireproof isolation layer.
Description
Technical field
The utility model relates to a kind of cable, and relating in particular to a kind of insulating barrier is having hardening under flame or the nonflame condition more than 400 ℃, and along with temperature raises, is sintered into the fireproof cable of ceramic-like.
Background technology
The application places of cable is comparatively complicated, and these complicated places have proposed challenge to the safe operation of cable.It is to affect one of of paramount importance factor of cable running safety that fire is suffered from, and how to guarantee the normal operation of cable under hot conditions, is the cable manufacturing enterprise technical issues that need to address.
A kind of ceramic fireproof＝fire-proof cable is disclosed in the Chinese utility model patent (patent No. 201120578978.8), comprise some cable cores, the ceramic silicone rubber fireproof flame retardant coating that each cable core comprises a conductor and coats this conductor, the ceramic silicone rubber fireproof flame retardant coating of cable core is outside equipped with insulating barrier, be provided with high temperature resistant packed layer between these cable cores, and oversheath.Because be provided with insulating barrier between the conductor of cable core and the ceramic silicone rubber fireproof flame retardant coating, the insulation property that this can improve cable conductor prevent that cable from causing the phenomenon of puncture owing to insulation property are low, be applicable to low pressure, medium and high pressure cable.
This cable just arranges one deck ceramic silicone rubber fireproof flame retardant coating in the periphery of conductor, and this fireproofing of cable effect is relatively relatively poor.In the fire, cable be subjected to sometimes less of fiery position, be not that whole cable all burnt roasting, the fireproof＝fire-proof layer of this individual layer is easily damaged because of differential hardening, thereby loses the protective effect to cable.
Summary of the invention
For overcoming defects, the utility model technical issues that need to address are: a kind of ceramic fireproof cable is provided, and this fireproofing of cable is effective, can the fail safe of Effective Raise fireproofing of cable.
For solveing the technical problem, the technical solution of the utility model: a kind of ceramic fireproof cable, comprise oversheath and be located at the interior cable of oversheath, but cable comprises the insulating barrier of metallic conductor and ceramic, and insulating barrier is positioned at the periphery of metallic conductor, it is characterized in that, in oversheath, be provided with metal sheath, but be provided with the fire lagging of ceramic in the metal sheath, described cable is positioned at fire lagging, and the periphery in cable in the fire lagging is filled with filler.The dustless mineral wool rope of the characteristics such as that the optional usefulness of filler has is fire-retardant, fire-resistant, low smoke and zero halogen.The material main component that plays the ceramic characteristic in insulating barrier and the fire lagging is silicon rubber, mica powder, mineral silicate, fire retardant, reinforcing filler etc.; when cable is subjected to fire; these become branch's sintering hardening and show as the characteristic of ceramic, thereby provide protection for cable.
As preferably, insulating barrier is by two-layer at least gold mica tape and wrapped the forming of some composite fire bands.This convenient periphery at cable forms this insulating barrier, and insulating barrier is lapping structure, also is suitable for the production to cable big-length, serialization.
As preferably, but the composite fire band is to be formed by glass-fiber-fabric and the calendering of ceramic silastic mixture.Being provided with of glass-fiber-fabric helps improve intensity when but ceramic silicon rubber shows as ceramic characteristics, also is convenient to the moulding of composite fire band simultaneously.
As preferably, described insulating barrier periphery is provided with the self-adhesion lapping layer, and this self-adhesion lapping layer forms in the insulating barrier periphery by the self-adhesion plastic tape is wrapped.But the self-adhesion lapping layer is the wrapped plastic tape of common self-adhesion, and its effect is with by wrapped and insulating barrier that form closely is wrapped in the conductor periphery.
As preferably, but described fire lagging is extruded by the silicon rubber of ceramic and forms.This has made things convenient for the moulding of fire lagging.
As preferably, described metal sheath is interlocking armouring stainless steel band.Stainless steel band forms metal sheath by the interlocking armouring, and the radial and axial intensity of this metal sheath all can be guaranteed, so that the anti-extraneous mechanical damage ability of whole cable is strong.
The beneficial effects of the utility model are: fire lagging is arranged on the inboard of metal sheath; both fit for they; when cable is subjected to fire; metal sheath can be heat promptly from being subjected to the fire place toward conduction all around; when but fire lagging reaches the temperature of ceramic; the circumferential integral body of fire lagging can promptly be sintered into hard, the complete housing of ceramic-like, thereby provides good protective effect for the cable of cable inside.Fire lagging just can show the characteristic of ceramic at the beginning of fire, this can effectively protect the insulating barrier on the cable.But fire lagging and insulating barrier all can show as the characteristic of ceramic under hot conditions, and this provides dual protection for cable, so that this fireproofing of cable performance is good.
Description of drawings
Fig. 1 is the end view drawing of the utility model ceramic fireproof cable.
Embodiment
See among the figure, the structure of the utility model ceramic fireproof cable comprises oversheath 1 and cable, and cable is arranged in the oversheath 1.
The structure of cable comprises metallic conductor 7 and insulating barrier 6, and insulating barrier 6 is arranged on the periphery of metallic conductor 7.The structure of insulating barrier 6 comprises two-layer gold mica tape and some composite fire bands, and the outer peripheral face at metallic conductor 7 forms insulating barrier 6 by wrapped mode for two-layer gold mica tape and these composite fire bands.Wherein, but the composite fire band is to be formed by glass-fiber-fabric and the ceramic silicon rubber mixture mode by calendering.For the insulating barrier 6 to this structure is fixed and wraps up, be provided with self-adhesion lapping layer 5 in the periphery of this insulating barrier 6, self-adhesion lapping layer 5 is to be formed on the outer peripheral face of insulating barrier 6 by wrapped mode by the self-adhesion plastic tape.
Be provided with fire lagging 3 and metal sheath 2 in the outside of cable in oversheath 1, fire lagging 3 is positioned at the inboard of metal sheath 2.But fire lagging 3 is the silicon rubber by ceramic to be formed by the form that extrudes, and metal sheath 2 is to be formed by the wrapped periphery at fire lagging 3 of interlocking armouring by stainless steel band.
Cable is four, and they all are positioned at fire lagging 3, and all tangent with the inwall of fire lagging 3.Periphery in cable in fire lagging 3 is filled with filler 4, and filler 4 is to be made of the dustless mineral wool rope with flame-retarding characteristic.
