Abstract
The invention relates to the technical field of the cables and in particular relates to a flexible fire resistant cable. The flexible fire resistant cable comprises a wire body; the wire body is provided with a conductor, a fire resistant layer, an expansion layer and a protective layer orderly from inside to outside; the conductor is composed of a single-core or multi-core cable; the fire resistant layer is made of a fire resistant inorganic short fiber material; the expansion layer is formed by wrapping an inorganic fire resistant expansion tape; the protective layer is formed by using a plurality of layers of metal woven meshes. When the flexible fire resistant cable is used, the fire resistant layer, the expansion layer and the protective layer are used for preventing fire, the working temperature of the cable is effectively increased so that the cable can be used in an environment below 800 DEG C for a long time, and the cable has excellent bending property and is convenient for construction. The flexible fire resistant cable has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.
Description
Technical field
The present invention relates to a kind of cable technology field, particularly a kind of flexible fire-resisting cable.
Background technology
The economy of high speed development has brought a lot of facilities, to environment band a lot of pollutions; In such situation, people just more and more pay attention to social environment.Traditional cable great majority are all combustible materials, produce solid granule and form smog after burning, have reduced light transmittance; Some material also contains halogen in addition, the pernicious gas (hydrogen halides) producing after burning, the respiratory system of harm people; Smog in these fire and toxic gas are the key factors that hinders rescue and escape, cause casualties.
In order to address this problem, on market, there is a kind of mineral insulation fire-resisting cable, although there is high serviceability temperature, and after catching fire, still can keep the long duration to continue power supply, cable also exist voltage withstand class low, manufacture complicated, involve great expense and shortcoming that bending property is poor etc.Therefore, how to provide one to have excellent bending performance, the problems such as the resistant to elevated temperatures cable of energy have become the focus of research in the industry.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, a kind of flexible fire-resisting cable simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution used in the present invention is:
The flexible fire-resisting cable of one of the present invention; comprise line body; described line body is from interior conductor, flame retardant coating, expanding layer and the protective layer of being provided with successively outward; described conductor is made up of single core or multicore cable; described flame retardant coating is that fire-resistant inorganic short fiber material is made; described expanding layer is wrapped the forming of inorganic fire-resistant zone of swelling, and described protective layer is made up of some layers of metal net.
Further, the litzendraht wire diameter of described metal net is less than 2mm, and the quantity of described metal net is three layers.
Further, the litzendraht wire of described metal net is copper cash.
Adopt after said structure; beneficial effect of the present invention is: the flexible fire-resisting cable of one of the present invention; comprise line body; described line body is from interior conductor, flame retardant coating, expanding layer and the protective layer of being provided with successively outward; described conductor is made up of single core or multicore cable; described flame retardant coating is that fire-resistant inorganic short fiber material is made, and described expanding layer is wrapped the forming of inorganic fire-resistant zone of swelling, and described protective layer is made up of some layers of metal net.Use time of the present invention, prevent fires by flame retardant coating, expanding layer and protective layer, effectively improved cable working temperature, can make cable below 800 DEG C, in environment, use for a long time, and there is good bending property, can constructability.The advantages such as the present invention has simple in structure, arranges rationally, and cost of manufacture is low.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Description of reference numerals:
1, line body; 2, conductor; 3, flame retardant coating; 4, expanding layer; 5, protective layer.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, the flexible fire-resisting cable of one of the present invention, comprises line body 1, and described line body 1 is from interior conductor 2, flame retardant coating 3, expanding layer 4 and the protective layer 5 of being provided with successively outward, and described conductor 2 is made up of single core or multicore cable.
Described flame retardant coating 3 is made for fire-resistant inorganic short fiber material, and fire-resistant inorganic short fiber of the present invention can be alumina short fibre or zirconia short fiber etc., can be also a kind of short fiber of combination.Short fiber has good fire resistance, and actual work temperature can reach more than 800 DEG C, also has good flexibility and elasticity simultaneously.
The inorganic fire-resistant zone of swelling of expanding layer 4 of the present invention adopts wrapped form, like this, is not only conducive to improve cable bend, and can bears higher ignition temperature.Inorganic fire-resistant zone of swelling of the present invention is made up of inorganic fire proof material and expanding fire retardant glass fibre base band one side or double face binding, or also can directly buy in market.
Described protective layer 5 is made up of some layers of metal net, and the litzendraht wire diameter of described metal net is less than 2mm, and the quantity of described metal net is three layers, and the litzendraht wire of described metal net is copper cash.
The present invention is in the time meeting fire; expanding layer 4 in protective layer 5 produces to expand and compresses; not only can play heat insulation reduction temperature; and can make the structure of flame retardant coating 3 more stable; thereby can bear the External Force Acting insulation such as water pouring, vibration, impact and not damage, can keep long-time normal power supply.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only preferred embodiments of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
