Description

Fire-fighting cable for high-speed rail transit Technical Field The utility model relates to the technical field of cables, in particular to a fire-fighting cable for high-speed rail transit. Background In a high-speed rail transit system, a cable is used as a key carrier for electric energy and signal transmission, and the safety and reliability of the cable are important. Because the track traffic environment is complicated, the circuit is laid densely, once a fire disaster occurs, the fire is very easy to spread, and the rescue difficulty is very high. In a fire disaster, the insulation and sheath materials of the traditional cable are easy to be ignited by flame, so that the fire accident is further expanded, and the control circuit of fire-fighting equipment, the signal transmission circuit of a fire automatic alarm system, the fire-fighting broadcasting circuit, the fire-fighting telephone circuit and the like can be damaged by the flame, thereby seriously delaying the rescue time and causing huge life and property loss. In addition, the electric wire and cable burning has the characteristics of strong concealment, quick propagation, high smoke toxicity and the like, and is extremely unfavorable for fire prevention and control. Along with the rapid development of rail transit, the requirements on fire-resistant cables for guaranteeing continuous power supply of fire protection under fire working conditions are continuously improved, and the existing common cables are difficult to meet the severe requirements, so that a fire-resistant cable with excellent performance for high-speed rail transit is urgently needed, and the fire-resistant equipment of a rail transit system can normally operate under extreme conditions such as fire, so that precious time is strived for personnel evacuation and rescue work. The utility model provides a CN202222795222.X discloses a fire control cable, including control core and a plurality of power core, control core and power core transposition form the cable core, control core is including the first core that is located cable core central point department and the second core that is located first core periphery, power core and the coaxial setting of control core, a plurality of power cores arrange in the periphery of first core along circumference, the second core is located between the adjacent power core, between first core and the second core, between first core and the power core, and all be equipped with insulating filler between second core and the control core, the insulating filler of this fire control cable improves fire resistance, guarantee the integrality of this fire control cable circuit, accord with fire control operation requirement, control core can provide power supply for equipment such as signboard, warning light, power core can provide continuous power supply for fire control equipment such as spray set, the quantity of fire control cable is reduced to this fire control cable, the compliance is high, the degree of difficulty is low, nevertheless, when there is not being not enough the device when using, when needs to be connected with other connecting wire, the wire through the fork is the corresponding device that need be winded at the certain work of this kind of insulating tape that need to do not carry out. Disclosure of utility model The invention aims to provide a fire-fighting cable for high-speed rail transit, which solves the problem that when the fire-fighting cable is used and needs to be connected with other connecting wires, the forked and scattered wires need to be further wound through insulating tapes, so that the fire-fighting cable has certain inconvenience in corresponding connection work. In order to solve the technical problems, the utility model is realized by the following technical scheme: the utility model relates to a fire-fighting cable for high-speed rail transit, which comprises a protective sleeve component, wherein the front end of the protective sleeve component is fixedly provided with a fastening connection component, and the interior of the protective sleeve component is fixedly provided with a conductor component; The fastening connection assembly comprises a silica gel support sleeve, a heat dissipation hole is formed in the outer side of the tail end of the silica gel support sleeve, and the front end of the silica gel support sleeve is fixedly provided with the fastening assembly.
