Description
Technical field
The utility model relates to a kind of cable, especially a kind of copper sheath mineral insulation fire-resisting cable.
Background technology
Present cable use is more and more wider, such cable will be applied in each complex environment, just require that cable will have various resistance properties, in prior art, not there is good fire protecting performance, need the environment of fire resistance in breaking out of fire or special producing under, cable is just easy to melt, and exposes conductor, causes electronics accident or electronic failure occurs.
Utility model content
Technical problem to be solved in the utility model is to provide the good and corrosion resistant copper sheath mineral insulation fire-resisting cable of a kind of fire protecting performance.
The utility model solves the technical scheme that its technical problem adopts: a kind of copper sheath mineral insulation fire-resisting cable, comprises conductor and envelopes inorganic ceramic powder insulating barrier, copper sheath, the corrosion-resistant sheath of oxygen barrier of conductor successively.
Further, the corrosion-resistant sheath of described oxygen barrier adopts hydroxylapatite ceramic to make.
Further, anti-water barrier layer is provided with between described inorganic ceramic powder insulating barrier and copper sheath.
Further, described anti-water barrier layer adopts polyvinyl chloride to make.
The beneficial effect of utility model is: cable has good fire resistance and insulating properties, and cable also has waterproof, the feature such as corrosion-resistant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Shown in figure: 1-conductor, 2-inorganic ceramic powder insulating barrier, the anti-water barrier layer of 3-, 4-copper sheath, the corrosion-resistant sheath of 5-oxygen barrier.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of copper sheath mineral insulation of the utility model fire-resisting cable, comprises conductor 1 and envelopes inorganic ceramic powder insulating barrier 2, copper sheath 4, the corrosion-resistant sheath 5 of oxygen barrier of conductor 1 successively.Wherein namely inorganic ceramic powder insulating barrier 2 is the insulating barrier adopting inorganic ceramic powder to make, and has the good and advantage of preventing fires etc. of good insulating, high-wearing feature, corrosion resistance, can allow this cable is heat-resisting, corrosion-resistant, good insulating like this; Copper sheath 4 can avoid the exposure of conductor 1, and low price, is applicable to large-scale production, and the corrosion-resistant sheath 5 of oxygen barrier improves the corrosion resistance of cable and starvation further, extends the useful life of cable.
The material of conductor 1 can select copper, aluminium alloy etc., wherein the low price of copper, and production cost is low; Aluminium alloy then not only can saving copper resource, Appropriate application bauxite resource; Also can alleviate the weight of cable, reduce the wearing and tearing of installation cost, minimizing equipment and cable, make installment work lighter.
The material of the corrosion-resistant sheath 5 of oxygen barrier can adopt inorganic material, metal material etc., and preferred embodiment, the corrosion-resistant sheath 5 of described oxygen barrier adopts hydroxylapatite ceramic to make.Cable is allowed to have fire prevention, waterproof, anticorrosion etc. like this.
In order to improve the water resistance of cable, preferred embodiment, anti-water barrier layer 3 is provided with between described inorganic ceramic powder insulating barrier 2 and copper sheath 4.
The material of anti-water barrier layer 3 can adopt haloflex, neoprene etc., and as preferred embodiment, described anti-water barrier layer 3 adopts polyvinyl chloride to make.It has good water-proof function and band barriering effect, also ageing-resistant, corrosion-resistant etc. advantage.
