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 fire rescue comprises a plurality of conductors 1, the conductors 1 are externally extruded with an insulating layer 2 to form an insulating wire core, a temperature sensing wire 3 is arranged at the center of the insulating wire core, a flame-retardant filling layer 4 is arranged outside the insulating wire core, and the flame-retardant filling layer 4 is sequentially provided with a wrapping layer 5, a ceramic silicon rubber layer 6, an aluminum alloy belt armor 7 and a sheath 8. The cable is at fire rescue operation in-process, if when being in high hot environment, the temperature-sensing line of heat transfer center department, the temperature-sensing line can fuse when reaching the settlement threshold value, do not influence the normal operation of cable but the electric power monitoring part can remind this moment, so can know the high temperature point of cable, in time cool down the processing, the spontaneous combustion problem that the too high arouses of avoidance cable temperature that can be better, the fire-proof material that the insulating core used outward is environmental protection material, improve 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 in the center of the insulated wire core. 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 an embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
