Abstract
The utility model discloses a kind of flame-retardant fire-proof cables, it is disposed with shielded layer, insulating layer and external sheath layer from inside to outside including cable core, the cable core, the cable core includes three conductors and the cable core filling for filling cable core gap, it is pasted on the inner wall of the shielded layer and is provided with fire resistant film layer, the cable core is fixedly connected fire resistant film layer by several connecting rods, it is filled with fire-resistant fluid between the fire resistant film layer and cable core, fire extinguishing layer of sand is additionally provided between the insulating layer and external sheath layer.The setting of fire extinguishing layer of sand and fire-resistant fluid is so that cable has the good double-deck fire protection flame retarding defencive function in the utility model; so that flame is difficult to go beyond fire extinguishing layer of sand and touches cable interior section; even if having gone beyond fire extinguishing layer of sand; fire-resistant fluid also can be good at protecting cable core; so that the flame retardant property of cable entirety is very prominent, the whole using effect of cable is greatly improved.
Description
Technical field
The utility model relates to field of cables, and in particular to a kind of flame-retardant fire-proof cable.
Background technique
The method that existing flame-retardant electric wire and cable generally uses is exactly to add to contain in the materials such as insulation, sheath and filling
The halide and metal oxide of halogen, are evaluated from fire-retardant angle, this is fabulous method, still, due to these materials
In contain halide, discharge a large amount of smog and hydrogen halide in burning, so, personnel are given in low visibility when fire
Safe escape and fire hose carry out very big obstruction, and people then more dies of asphyxiation for toxic gas, if not adding halogenation
Object then only promotes the flame retardant property of cable in the structure of cable itself, but existing cable shield, insulating layer and
Restrictive coating all successively fits closely, and is unfavorable for the heat dissipation of cable, can be fired in a very short period of time if fire occurs and
Shielded layer and insulating layer can finally destroy cable conductor, and the conductor in cable conductor is the core of cable, once conductor quilt
It burns out, then cable just loses its transfer function.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, it is good and electricity can be prevented to provide a kind of flame retardant property
Cable cable core is broken outer flame-retardant fire-proof cable.
Technical solution: to achieve the above object, the utility model provides a kind of flame-retardant fire-proof cable, including cable core, institute
It states cable core and is disposed with shielded layer, insulating layer and external sheath layer from inside to outside, the cable core includes three conductors and filling
The cable core in cable core gap is filled, and is pasted on the inner wall of the shielded layer and is provided with fire resistant film layer, if the cable core passes through
Involvement extension bar is fixedly connected fire resistant film layer, and fire-resistant fluid, institute are filled between the fire resistant film layer and cable core
It states and is additionally provided with fire extinguishing layer of sand between insulating layer and external sheath layer.
The design principle of the utility model: layer of sand of putting out a fire in the utility model has fabulous fire protecting performance, can prevent
The intensity of a fire is quickly spread to insulating layer；The setting of fire-resistant fluid is played the role of protecting cable core, reduces high temperature and flame for cable
The influence of core, and because fire resistant film layer has certain ignition temperature, once ignition temperature is very high, have exceeded anti-
The scope of application of fiery liquid, fire resistant film layer are fallen by flame combustion, and connection is then lost between such cable core and shielded layer and is made
With can prevent cable core from being destroyed by detaching cable core inside cable.
Further, three conductors are respectively connected with the heat-insulated stick of conductor between any two, and it is exhausted that the conductor is coated with conductor
Edge layer, the surface of the insulating layer of conductor are provided with flame-resistant resin dope layer, and flame-resistant resin dope layer has fabulous fire line
Can, to improve the flame retardant property of conductor.
Further, the cable core is filled with the filling of flame resistant glass cotton.
The utility model has the advantages that the utility model compared with prior art, has following advantage:
1, put out a fire layer of sand and fire-resistant fluid setting so that cable has the good double-deck fire protection flame retarding defencive function so that
Flame is difficult to go beyond fire extinguishing layer of sand and touches cable interior section, even if having gone beyond fire extinguishing layer of sand, fire-resistant fluid also can be good at
Cable core is protected, so that the flame retardant property of cable entirety is very prominent, without using halide and metal oxidation
In the case where object, cable can have fabulous flame retardant property, greatly improve the whole using effect of cable；
2, serious when encountering combustion case, temperature is excessively high, and when flame is uncontrollable, fire resistant film layer is fired by flame
Burn-up, then loses connection function between such cable core and shielded layer, can prevent cable by detaching cable core inside cable
Core is destroyed, to ensure that the integrity degree of cable core.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after having read the utility model, art technology
Personnel fall within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
As shown in Figure 1, the utility model provides a kind of flame-retardant fire-proof cable, including cable core 1, the cable core 1 by introversion
It is disposed with shielded layer 2, insulating layer 3 and external sheath layer 5 outside, the cable core 1 includes that three conductors 6 and filling cable core 1 are empty
The cable core of gap fills 9, pastes on the inner wall of the shielded layer 2 and is provided with fire resistant film layer 8, the cable core 1 passes through several
Connecting rod 11 is fixedly connected fire resistant film layer 8, and fire-resistant fluid is filled between the fire resistant film layer 8 and cable core 1
10, fire extinguishing layer of sand 4 is additionally provided between the insulating layer 3 and external sheath layer 5, three conductors 6 are respectively connected between any two
The heat-insulated stick 7 of conductor, the conductor 6 are coated with insulating layer of conductor 61, and the surface of the insulating layer of conductor 61 is provided with flame-resistant resin
Dope layer 62, the cable core filling 9 are filled for flame resistant glass cotton.
When combustion case is serious, the intensity of a fire is swift and violent, flame contact to fire resistant film layer 8, fire resistant film layer 8 because
Burning atrophy occurs for the reason of high temperature and flame itself, and such cable core 1 and shielded layer 2 lose connection, can at once by cable core 1 from
It is detached inside cable.
