Description
Technical field:
The utility model relates to a kind of low smoke, zero halogen fire resistant flame retardant cable for track traffic.
Background technology:
At present, domestic fire-resisting cable generally adopts fire-resistant isinglass belt lapping layer as cable fire layer, and LSOH anti-flaming glass fibre belt class material, the low cigarette polyolefine material of high-flame-retardanthalogen-free halogen-free are as the refuge floor (or claiming oxygen barrier layer) of cable.Track traffic DC traction cable insulating material is crosslinked polyethylene, ethylene-propylene rubber, and watertight composition mainly adopts aluminum plastic composite belt longitudinal bag to add pe sheath.In a fire, LSOH anti-flaming glass fibre belt class material, the low cigarette polyolefine material of high-flame-retardanthalogen-free halogen-free can stand the baked wheaten cake of certain hour as the refuge floor (or claim oxygen barrier layer) of cable, as continued to be burnt, LSOH anti-flaming glass fibre belt class material is burnt brokenly, the low cigarette polyolefine material of high-flame-retardanthalogen-free halogen-free gradually powders and comes off, and the crosslinked polyethylene of insulating barrier, ethylene-propylene rubber and watertight composition polyethylene are combustible materials, at high temperature become viscous state already, burn once meeting fire, send a large amount of black smoke, and play the reaction helping fire to stretch, refuge floor thus lose protective effect.When flame breaks through to flame retardant coating, the last line of defense that fire-resistant isinglass belt lapping layer will be whole cable fire-proof, now, fire-resistant isinglass belt lapping layer under hot environment before, already by the crosslinked polyethylene of insulating barrier, ethylene-propylene rubber dipping, in fire endurance period combustion process, fire-resistant isinglass belt lapping layer gradually burns brokenly, peels off, thus lost efficacy, electric wire is easy to breakdown and causes short circuit, thus is difficult to ensure electric power in case of fire safe and smooth.Common fire-resisting cable, by correlation test, meets relevant criterion requirement, but fire-resistant reliability is not high.
Summary of the invention:
The utility model proposes a kind of low smoke, zero halogen fire resistant flame retardant cable for track traffic, its objective is that will to provide a kind of fire-resistant, fire-retardant, waterproof, nontoxic, environmental protection, fail safe high, under being suitable for specific disaster scenario, still can maintain the cable for rail transit of energising.
Technical solution of the present utility model: the cross-sectional structure of this cable is form concentric circles by conductor, fireproof mica belt, the first fire-resisting ceramic silicone rubber layer, Halogen low-carbon (LC) cross-linked polyolefin insulating barrier, mineral wool rope watertight composition, the first glass fibre belt, the second fire-resisting ceramic silicone rubber layer, the second glass fibre belt, halogen-free low-smoke high-flame material restrictive coating successively from inside to outside.
The beneficial effects of the utility model: the 1. compound flame retardant coating adopting fire-resistant isinglass belt and the first fire-resisting ceramic silicone rubber composition, can improve the fire resistant flame retardant of cable, make this cable fire effect properties excellent, close to mineral insulated cable performance.2. outside is provided with halogen-free low-smoke high-flame material restrictive coating, can prevent mouse ant from biting, the safety of protection cable.
Accompanying drawing illustrates:
Accompanying drawing 1 is cross-sectional structure schematic diagram of the present utility model.
In figure 1 is conductor, 2 are fireproof mica belts, 3 are first fire-resisting ceramic silicone rubber layers, 4 are Halogen low-carbon (LC) cross-linked polyolefin insulating barriers, 5 are mineral wool rope watertight compositions, 6 are first glass fibre belts, 7 are second fire-resisting ceramic silicone rubber layers, 8 are second glass fibre belts, 9 is halogen-free low-smoke high-flame material restrictive coatings.
Embodiment:
As shown in Figure 1, the cross-sectional structure of this cable is for form concentric circles by conductor 1, fireproof mica belt 2, first fire-resisting ceramic silicone rubber layer 3, Halogen low-carbon (LC) cross-linked polyolefin insulating barrier 4, mineral wool rope watertight composition 5, first glass fibre belt 6, second fire-resisting ceramic silicone rubber layer 7, second glass fibre belt 8, halogen-free low-smoke high-flame material restrictive coating 9 successively from inside to outside.
The sectional area of conductor 1 of the present utility model is 120 ~ 1000mm2, and geometry is round, is well-regulated by the soft round copper wire that some diameters are identical, concentric type, and successive layers time is according to different directions strand system.Flame retardant coating to extrude with the additional first fire-resisting ceramic silicone rubber layer 3 of the fireproof mica belt 2 of special high-quality Mica tape or wrapped, vertical bag combines, mica tape has excellent fire resistant flame retardant effect, and still can keep excellent dielectric strength under ignition temperature.First fire-resisting ceramic silicone rubber layer 3 adopts fire-resisting ceramic silicone rubber insulating material, nonpoisonous and tasteless at normal temperatures, has good flexibility and elasticity, and good processability.Under high temperature more than 500 DEG C and flame ablation, organic principle ablatedly in a short period of time can change into hard ceramic-like material, form the isolation layer that one deck is good, to stop that flame and other material enter Mica tape layer, Mica tape layer not by other Substances Pollution also not with flame contact.The fire-resisting ceramic silicone rubber insulating material ablation time is longer, and temperature is higher, and hard effect is more obvious, the fire-resistant environment of 1200 ~ 1500 DEG C can be reached, by burning after remain without any ashes, there are good insulation property simultaneously, and resistance to Water spray, vibrations.The composite fire layer of fireproof mica belt 2 and the first fire-resisting ceramic silicone rubber layer 3 composition really serves excellent fireproofing function and the object of safety and environmental protection.Halogen low-carbon (LC) cross-linked polyolefin insulating barrier 4 adopts the cross-linked polyethylene insulating material of Nano titanium dioxide, effectively suppresses space charge by Nano titanium dioxide particle, reinforced insulation electrical breakdown performance, increases cable useful life.Mineral wool rope watertight composition 5 adopts mineral wool rope to fill and forms.Refuge floor is formed by three layers, and internal layer is the first glass fibre belt 6, and centre is the second fire-resisting ceramic silicone rubber layer 7, and skin is the second glass fibre belt 8.When cable is heated in a fire, material expansion within refuge floor, the first glass fibre belt 6 cushioning effect.Second glass fibre belt 8 is as the buffer protection effect between the second fire-resisting ceramic silicone rubber layer 7 and halogen-free low-smoke high-flame material restrictive coating 9.Halogen-free low-smoke high-flame material restrictive coating 9 adopts special high-quality halogen-free low-smoke high-flame material, has low smoke, zero halogen, antiultraviolet, fire-retardant, the anti-ant of category-A, protection against rodents, safety and environmental protection performance.
