Drawings
FIG. 1 is a schematic cross-sectional view of an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and embodiments.
As shown in figure 1, an environmental protection cable for safety fire control, includes a plurality of conductors 1, conductor 1 is crowded package outward has insulating layer 2 to become the insulation core, the interval is provided with temperature-sensing line 3 between the insulation core, the insulation core is provided with fire-retardant filling layer 4 outward, fire-retardant filling layer 4 has set gradually outward around covering 5, ceramic silicon rubber layer 6, aluminum alloy area armor 7 and sheath 8.
The cable is at fire rescue operation in-process, if when being in complicated high fever environment, for example when passing through the scene of a fire, the cable probably passes through the burning zone, or when having no naked light and high heating area, the regional department of cable contact high fever probably is heated partially, and the temperature-sensing line of center department is arrived in heat transfer, can fuse when the temperature-sensing line reaches the settlement threshold value, does not influence the normal operation of cable but the electric power monitoring part has the warning this moment, but can know the high temperature point of cable, in time cools down the processing. The spontaneous combustion problem that the conductor high temperature arouses can be better avoided, and the fire prevention material that the insulating core used outward is environmental protection material, improves the quality of cable.
The ceramic silicon rubber can release a large amount of crystal water when being burnt in fire and can form a hard shell, and the aluminum alloy strip armor 7 has good heat conductivity and flame retardance. The use of the ceramic silicone rubber layer 6 and the aluminum alloy strip armor 7 provides the cable with high flame-retardant, fire-resistant, spray-water and weight drop impact resistant characteristics.
In one embodiment, the insulated wire cores are uniformly distributed in the flame-retardant filling layer 4, and the temperature sensing wire 3 is arranged between every two adjacent insulated wire cores and close to one side of the wrapping layer. Insulating sinle silk evenly distributed does benefit to the stranding in fire-retardant filling layer 4, makes the cable mellow and full, and temperature-sensing line 3 sets up and more does benefit to the response of cable internal temperature in the middle of the insulating sinle silk.
In one embodiment, the temperature sensing wire 3 has a diameter of 1-3 mm. The temperature sensing wire 3 is too thin, so that the temperature sensing wire is easy to break and is not beneficial to installation, and the temperature sensing wire 3 is not easy to fuse and give a warning if the temperature sensing wire is too thick, so that the diameter of the temperature sensing wire 3 is set to be 1-3 mm in comprehensive consideration.
In one embodiment, the fusing temperature of the temperature sensing line 3 is 150-. The temperature of the insulated wire core exceeds 150-180 ℃, spontaneous combustion is easy to occur to cause fire, the fusing temperature of the temperature sensing wire 3 is set in the interval, and fusing is realized when the fusing threshold is reached, the circuit monitoring part displays, the high-temperature section of the cable is easy to detect, the prevention of the fire can be facilitated, and the effect of safe fire fighting is realized. The method is particularly suitable for places with heavy electric loads.
In one embodiment, the flame retardant filler layer 4 is an inorganic mica filler layer. The inorganic mica filling layer is made of inorganic flame-retardant materials, does not generate smoke or other toxic gases when burning in fire and is an environment-friendly cable material, and the inorganic mica filling layer is economical in price and beneficial to reducing the production cost of cables.
In one embodiment, the wrapping layer 5 is a double-layer waterproof insulating cloth. The inorganic mica filling layer is low in price and good in fireproof performance, but the defect that the inorganic mica filling layer is easy to absorb water is overcome, and the double-layer waterproof insulating cloth is used for avoiding the problem that the inorganic mica filling layer absorbs moisture to damp the interior of the cable.
In one embodiment, the jacket 8 is a low smoke, zero halogen, flame retardant jacket. The low-smoke halogen-free flame-retardant sheath is used, so that less smoke and less toxic gas are generated in case of accidental fire, and the use is more environment-friendly.
The above description is only one specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any changes or modifications within the field of the present invention by those skilled in the art are covered within the scope of the present invention.
