A kind of fire protection flame retarding cable
Technical field
This utility model relates to electric power facility field, is specifically related to a kind of fire protection flame retarding cable.
Background technology
Cable is typically to be made up of several or several groups of wires.Cable has power cable, controls cable, compensating cable, shielding Cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, cable for ship, mine cable, aluminium alloy Cable etc..They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc..Cable is according to light The system of overhead utility can be divided into direct current cables and ac cable.Manufacturing and the mode of production of most of electronic products of electric wire It is diverse.Electronic product generally use assemble parts into a unit, multiple parts refill and are made into separate unit product, product with Number of units or number of packages metering.Electric wire is with a length of basic measurement unit.All electric wires are all from the beginning of conductor is processed, Electric wire product is made plus insulation, shielding, stranding, sheath etc. layer by layer in the periphery of conductor.Product structure is more Complexity, the level of superposition is the most.The rated voltage of cable is equal to or more than the rated voltage of place network, the senior engineer of cable The 15% of its rated voltage is must not exceed as voltage.Except to move or to vibrate in addition to violent place employing copper core cable, general feelings Aluminium cable is used under condition.The cable in cable structures that is laid in preferably uses open armoring cable or aluminum bag naked plastic sheath electricity Cable.Direct-buried cable uses armored cable or the naked plastic jacketed cable of aluminum bag of band sheath.At present, along with the development of clean energy resource, Electric power resource high speed development, along with the construction of nuclear power station, power station and wind power generation, cable becomes conventional work in life Tool.
Because cable is transmitting electric power when, often because of at lug short circuit cause cable on fire, thus cause fire, Electric power remote conveying use bare wire to carry, but in productive life, because of safety, it is necessary to use and there is insulating outer layer Cable carries out power transmission, and existing cable exists because lug short circuit causes the potential safety hazard of fire.Cable is in the condition of a fire Under threat, on fire except at lug, also include the threat of external fire, existing cable designs, often just for outside Fire or joint fire carry out fire protection design, it is impossible to delay the time that the intensity of a fire is invaded.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of fire protection flame retarding cable, Use in providing amenities for the people, increases the safety used, delays the time that the intensity of a fire is invaded.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme: a kind of fire protection flame retarding cable, Including cable core, joint and flame-retardant expanded set, the end of described cable core is provided with joint, and described cable core is positioned at the rear of joint Sheathed flame-retardant expanded set, leaves spacing cavity between described joint and flame-retardant expanded set, the phase of described flame-retardant expanded set and joint Side indent respectively being offered the first groove and the second groove, places spring in described spacing cavity, the two ends of described spring are supported At the first groove and the bottom land of the second groove, described flame-retardant expanded set and joint are positioned at the side above the first groove and the second groove Wall is set to the first wave sidewall, agrees with the elastic gag of installation, outside the stick harness of described elastic gag between described first wave sidewall Sidewall is set to the second wave sidewall agreed with the first wave sidewall.
Preferably, the outside coated insulation layer of described cable core, the outside cladding thermal insulation layer of insulating barrier, the outside of thermal insulation layer Cladding flame resistant filler rope layer, the outside cladding waterproof layer of flame resistant filler rope layer.
Preferably, the outside coated Si rubber sheath of described flame-retardant expanded set.
Preferably, described spring is compressive state.
Preferably, the outer felt of described elastic gag is around waterproof adhesive tape.
This utility model is reached to provide the benefit that: this fire protection flame retarding cable, by the outside cladding at cable core absolutely Edge layer, thermal insulation layer, flame resistant filler rope layer and waterproof layer so that cable core has the function of fire protection flame retarding, effectively delay outside fire Gesture intrudes into the time of cable core, and the sheathed flame-retardant expanded set at the rear of joint, joint once produces thermal-flame, fire-retardant Expanded material in foaming set starts foaming, and temperature more high-foaming speed is the fastest, if by fire location, the bubble sent can be fast Speed is filled up near fire location, makes fire extinguish due to anoxia, thus plays fireproof effect, and joint flame on fire makes to connect Head material softens, and the extruding force that spring is subject to diminishes, and starts elongation, is pushed away by joint far, provides more for flame-retardant expanded set and sends out Bubble response time and covering space, the structure of improvement makes whole fireproofing and block burn of cable function more preferable.
