Abstract
The invention discloses a ceramic fireproof and heatproof cable, which comprises a ceramic silica gel insulating layer. The ceramic silica gel insulating layer wraps a fireproof wrapping layer, and is fixedly connected with the fireproof wrapping layer. An extruding layer is arranged inside the fireproof wrapping layer. The extruding layer is formed on the fireproof wrapping layer through integrated injection molding. Self-locking armored layers are arranged between the extruding layer and the fireproof wrapping layer and also between the extruding layer and the ceramic silica gel insulating layer. The self-locking armored layers are fixed on the fireproof wrapping layer, the ceramic silica gel insulating layer and the extruding layer. A copper wire shielding layer is arranged in the extruding layer, and is adhered to the extruding layer. The ceramic fireproof and heatproof cable is improved in both fire resistance and cable bending performance, exhibits more excellent bending performance, is convenient for laying for construction, can be used in high temperature environments, is flame-resistant to ensure safe power supplying once catching fire, and thus is greatly improved in flame resistance and environment protection.

Technical field
The present invention relates to a kind of cable, more particularly to a kind of ceramic fire resistant heat proof cable.
Background technology
It is to improve fire prevention peace as the development of society, skyscraper, the fire prevention of Important building are increasingly paid attention to by people
Congruent level, can generally adopt flame retardant cable, fire-resisting cable, aluminium sheath mineral insulated cable, high to fire protection requirement
Building, such as JinRong Building, major museum, large-scale theater can all select fireproof cable.Current heatproof flame-retardant cable it is exhausted
Edge layer and restrictive coating are usually to be mixed and made into single fire retardant and CABLE MATERIALS.The fire retardant for using in a large number is that an ancient small-mouthed wine vessel element class is fire-retardant
Agent, there is not flame-retarding power, but generates a large amount of smog and poisonous gas when burning, and its amount increasing with the temperature of burning and increasing, therefore only
Low-temperature flame retardant can be used for.It is recently used few without an ancient small-mouthed wine vessel element fire retardant smog, small toxicity or nontoxic, but containing a large amount of hydration materials,
Because dehydration reduces physics, the mechanical performance of cable when temperature is high, so resistance combustion temperature can not be high.In a word, due to
Using single fire proofing, cable is not to produce a large amount of smog and toxic gas just to reduce cable performance because of dehydration,
So as to affect the resistance combustion temperature and duration of fire resistance of cable.
The content of the invention

Between be fixedly connected, extruded layer is provided with fire resisting lapping layer, extruded layer integrated injection molding on fire resisting lapping layer, itself and fire resisting lapping layer
And self-locking armor is provided between ceramic silicone insulation layer, it is exhausted that self-locking armor is fixed on fire resisting lapping layer, ceramic silica gel
In edge layer and extruded layer, shielding layer of copper wires is provided with extruded layer, shielding layer of copper wires is bonded on extruded layer, in it conductor is provided with,
Conductor is fixed on extruded layer, and it is provided with electrostatic layer between extruded layer, and electrostatic layer coating conductor is arranged.
Further, as a kind of specific version, ceramic silicone insulation thickness degree of the present invention is less than resistance to
Fiery lapping layer thickness.
Further, as a kind of specific version, ceramic silicone insulation layer surface of the present invention is coated with
Wear-resistant sleeve.
Further, as a kind of specific version, wear-resistant sleeve surface distributed of the present invention has multiple salient points, convex
Point is integrally attached on wear-resistant sleeve.
Further, as a kind of specific version, self-locking armor of the present invention is aluminium, copper material structure.
Further, as a kind of specific version, electrostatic layer of the present invention is cylindrical structure.
Compared with prior art, it is an advantage of the current invention that：The ceramic fire resistant heat proof cable of the present invention, in fire prevention and cable
The aspect of bending property two is improved, and makes the bending property of cable more superior, is easy to construction to lay, can be making in hot environment
With, and can be fire-retardant down to safe power supply is kept after catching fire, so as to substantially increase the fire resistance and environmental protection characteristic of cable.
