Description
Technical field
The utility model relates to the rail locomotive cable, relates in particular to a kind of rail locomotive oilproof flame retardant cable, belongs to technical field of electric wires and cables.
Background technology
At present, the railroad track traffic has with power vehicle that fuel oil is driving, the driven by power type is in the majority.Wherein particularly the cable used of fuel combustion type locomotive some need fire-retardant, oil-resisting type cable.Because relevant criterion adopts insulating barrier and the restrictive coating of cross-linking radiation polyolefin as cable at present, it forms for dosing compound blend such as a lot of inorganic fire-retarded material in the high polymer, and this type of composite material exists that difficulty of processing is big, shortcomings such as the mechanical property of materials is lower, electric property is poor, oil resistance difference.
If adopt up-to-date engineering plastics class material, have some engineering plastics can satisfy cable performance and processing characteristics requirement, but often because engineering plastics price height causes cable cost too high, market is difficult to accept as insulating material and protective cover material.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of rail locomotive oilproof flame retardant cable is provided, making its tool satisfy the requirement of rail locomotives such as high flame retardant, oil resistant, heatproof with cable.
The utility model technical solution problem adopts following technical scheme:
The utility model rail locomotive is that conductor is by many stranded formation of tinned copper wire with the design feature of oilproof flame retardant cable, conductor and its appearance extrude the insulating barrier that forms by cross-linking radiation ethylene-tetrafluoroethylene copolymer XETFE and constitute insulated wire cores, adopt single insulated wire cores independently to constitute single core cable core, outside described single core cable core, extrude the restrictive coating that forms and form single-core cable by cross-linking radiation ethylene-tetrafluoroethylene copolymer XETFE; Or: adopt the stranded formation multicore of the edge core cable cores that thoroughly do away with more, in the gap of described multicore cable core packed layer is set, wrapped belting layer outside described packed layer and multicore cable core extrudes the restrictive coating that forms by cross-linking radiation ethylene-tetrafluoroethylene copolymer XETFE and forms multicore cable in described belting layer appearance.
Design feature of the present utility model also is:
Described conductor adopts the 6th class conductor.
The sectional area of the conductor in the described single-core cable is 0.5mm
2～300mm
2The sectional area of the conductor in the described multicore cable is 0.5mm
2～6mm
2, multicore cable the core number be the 2-48 core.
The material of described belting layer is polytetrafluoroethylene film band or fire-retardant thin non-woven fabric.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, insulating barrier and restrictive coating adopt cross-linking radiation ethylene-tetrafluoroethylene copolymer (XETFE) in the utility model, and its advantage comprises:
After a, material extrude into the edge layer extremely, adopt irradiation technique, make material form network structure, become insoluble molten thermosets, make the insulating barrier of cable have anti-cracking performance highly, also improved the heat resistance of insulating barrier by interconnect architecture;
The dielectric strength of b, material substantially exceeds the low smoke, zero halogen cross-linked polyolefin, and good electrical property meets the insulating performance of cable requirement;
C, temperature resistant grade are higher, and normal phase heat resisting temperature reaches 200 ℃, can satisfy the working temperature requirement at most of position in the locomotive;
D, Flame Retardancy can be good, and therefore, cable can be by fire-retardant A level bunched burning test;
E, material become molten under high temperature, high pressure, the suitable thin isolation layer of extruding;
F, material oil resistance are good, contact with oil product such as machine oil, and not serious expansion or contraction, after the immersion oil test, can be by withstand voltage test, so energy operate as normal under the mist of oil environment is being arranged.
2, the utility model conductor adopts the 6th class conductor, and by adopting burst strand and twisting regular lay configuration again, conductor has good flexibility on the one hand, and the conductive surface rounding property is good on the other hand, guarantees that the insulating barrier thickness is comparatively even when insulating exruded;
3, the utility model cable has restrictive coating, compares with no sheath type cable, has better fail safe, long-life property characteristics, and multicore cable is more more convenient than single-core cable laying installation.
