Gaps between the insulating wire cores in the cable core are filled with fillers, an isolating layer is arranged outside the cable core, and an aluminum sheath is arranged on the outermost layer. Since the aluminum sheath is arranged on the outermost layer, the cable can not burn under the open flame below 660 DEG C, and since the polymer material in the cable is isolated by the aluminum sheath, the burning condition can not be satisfied. Therefore, the utility model belongs to the flame retardant cable. Since the components in the sheath are all made of halogen-free material, and no halogen gas can be released, the utility model belongs to the new generation of fire safety and environmental protection control cable. The service life of the utility model reaches above 60 years, and the utility model can be used as the cable against water, rodents and termites. Moreover, the aluminum sheath has an excellent shielding performance and can substitute the total shielding layer of the existing cable.
Description
Technical field:
The utility model relates to a kind of non-halogen fire-retardant type control cable, belongs to technical field of electric wires and cables.
Background technology:
The used cable of all trades and professions is low-smoke halogen-free inflaming-retarding cable substantially at present, and to the characteristic requirement of cable low-smoke non-halogen flame-retardant is:
1, low smoke performance requires: minimum light transmittance 〉=60%;
2, Halogen performance requirement: pH value 〉=4.3, conductivity≤10 μ S/mm;
3, the bunchy fire resistance requires:
Category-A: comburant volume: 7L/m, for fire time: 40min, qualified index: the length of charing the most very much not should stop should not surpassing 1h for the flaming combustion time on the sample of fire back above the 2.5m that makes progress apart from the nozzle base on the sample;
Category-B: comburant volume: 3.5L/m, for fire time: 40min, qualified index: the length of charing the most very much not should stop should not surpassing 1h for the flaming combustion time on the sample of fire back above the 2.5m that makes progress apart from the nozzle base on the sample;
The C class: comburant volume: 1.5L/m, for fire time: 20min, qualified index: the length of charing the most very much not should stop should not surpassing 1h for the flaming combustion time on the sample of fire back above the 2.5m that makes progress apart from the nozzle base on the sample; The low-smoke halogen-free polyolefin insulation is adopted in the insulation of low-smoke halogen-free inflaming-retarding cable at present substantially, and sheath adopts low-smoke and halogen-free flame retardant polyolefin jacket; And above-mentioned all kinds of cable all is difficult to reach the performance requirement of smokeless non-halogen fire-retardant.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of non-halogen fire-retardant type control cable, is the new generation product that substitutes the low-smoke halogen-free flame retardant control cable, and cost is suitable, and electric fireproof safety and environmental protection effect are better.
The utility model technical solution problem adopts following technical scheme:
Non-halogen fire-retardant type control cable comprises the conductor wire core of cable, and extruded insulation layer outside conductor wire core thoroughly does away with the cable core that the edge core is twisted into more, and the space packing in cable core between the insulated wire cores has separator on cable core, and outermost layer is the metallic aluminium sheath.
Described conductor wire core adopts and meets the 1st kind or the 2nd kind or the 5th kind of conductor structure stipulating among the GB/T3956.
Described insulating barrier adopts polyethylene or crosslinked polyethylene or cross-linking radiation polyolefin insulation Halogen material to extrude and forms.
Described separator is to adopt wrapped the forming of high temperature resistance non halogen material band.
Described aluminium sheath adopts hot extrude bag molten aluminum or vertical alclad tape welding to connect and form through the embossing PROCESS FOR TREATMENT.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
(1) because of the outer jacket of the utility model cable for extruding aluminium sheath, the melting temperature of aluminium is 660 ℃, therefore, protective coverings of cable can not burn 660 ℃ of following temperature, insulation, filling and isolation and the lapping layer material of cable the inside are isolated by outer jacket again, cable itself do not contact with air, can't form the condition of burning, so can not produce dieseling because of aging, overload or short circuit yet.Eliminated the fire disaster that causes because of the cable spontaneous combustion, and the fire that cable causes causes direct or indirect economic loss in China is surprising, the utility model cable has thoroughly solved the difficult problem of the fire safety of control cable circuit, is the best fireproof cable of cost performance.
(2) because the utility model cable has only when the flame temperature of outside naked light is higher than 660 ℃ of temperature of metallic aluminium cover fusing point, after the cable cover(ing) fusing, it is burned that the material of cable the inside just has the part material, but be confined to very little scope.Therefore; this cable belongs to the nonflammable control cable; the burning back is in the test of GB/T19666 regulation; smoke density is greater than more than 90%; halogen gas disengages again, has the characteristic of few cigarette, Halogen and difficult combustion, and the secondary disaster of cable under the fire condition also significantly reduced; can not cause how many negative effects, be better than existing low-smoke halogen-free inflaming-retarding cable environmental protection.
(3) the utility model cable long service life.Because the aluminium of aluminium sheath contacts the back and forms layer of oxide layer on its surface with airborne oxygen, aluminium oxide has prevented the further oxidation of aluminium sheath, and therefore, the corrosion resistance of aluminium sheath is strong; The material and the air of cable the inside are isolated again, and the ageing process of insulation and other material delays greatly, can reach 60 the useful life of cable as calculated with last year.
(4) because cable jacket has adopted hot extrude bag or vertical bag welding of aluminum sheath, still do not have fire protecting performance, its antiseptic property, water resistance, can be used as submerged cable and use.
(5) because aluminium sheath has been carried out the embossing PROCESS FOR TREATMENT, the bending radius of the utility model cable can be compared with common cable, and installing does not need poling yet when laying.Saved the poling material.
(6) aluminium sheath also can be used as the screen use, has good shield effectiveness, the total screen in alternative original construction of cable, and therefore, the utility model cable does not need to add up in addition shielding construction.Saved the plastic sheath material of shielding material and cable.
After particularly cable has adopted and has extruded aluminium sheath; the too high cable heating that causes of short circuit, ambient temperature that causes wearing out owing to cable material etc. causes the phenomenon of cable spontaneous combustion or else can take place; therefore; concerning electric fireproof safety and environmental protection, this will be a revolutionary innovation on the cable product.
