Abstract
The utility model relates to a thermal -insulated sections way supply cable, include from interior to superimposed copper conductor, insulating layer, waterproof layer, non -woven fabrics layer and PVC outer jacket in proper order outward be provided with a polyvinyl chloride keriotheca between waterproof layer and the non -woven fabrics layer, and then be provided with a setting phase change material layer between non -woven fabrics layer and the PVC outer jacket, and the surface of PVC outer jacket still is provided with an antiradiation coating. The utility model discloses a reflected radiation of antiradiation coating reaches thermal -insulated effect to still being provided with the polyvinyl chloride keriotheca, can further improving the thermal -insulated effect of this cable through the honeycomb interlayer that forms, still be provided with a great deal of setting phase change material simultaneously, phase change material follows solid state from the environment heat absorption and becomes the liquid state when ambient temperature is higher, heat altered is put for solid -state from the liquid state to phase change material when ambient temperature is lower to certain temperature regulation effect can be played, the high temperature of this cable can be effectively avoided.
Description
Technical field
The utility model relates to railway cable technical field, particularly relates to a kind of heat insulation type railway power supply cable.
Background technology
Along with the development of national economy, also development is rapid nearly ten years for the railway cause of China, and railway operation is totalMileage has exceeded 100,000 kilometers, and in 100,000 kilometers of railways, 120 kilometers of speed per hours and Above Transmission Lines exceed 40,000 public affairsIn, wherein 160 kilometers of circuits of speed per hour exceed 20,000 kilometers; High-speed railway is broken through 10,000 kilometers.
Current, railway and infrastructure are the major fields of government investment. Cable is called as the each row of national economy" nerve " of industry, exploitation and the process modification of electric wire in this type of field accelerated in reinforcement, is electric wireIndustry realizes product transformation upgrading and extricates oneself from a plight, obtains new growing point Important Action.
We know that temperature is lower, and the resistance of cable inner conductor is just less, and electrical transfer efficiency is also just higher, andContrary, in some hot desert areas, temperature is higher, makes the resistance of conductor larger, has reduced electricityEfficiency of transmission. Due to railway broad covered area, cable length is long, and the reduction of cable electrical transfer efficiency also canCause the waste of mass energy, therefore improve a large amount of effect of heat insulation and seem particularly important.
Utility model content
Therefore,, for above-mentioned problem, the utility model proposes a kind of heat insulation type railway power supply cable.
For realizing above-mentioned technical problem, the solution that the utility model is taked is: a kind of heat insulation type railway suppliesElectrical cables, comprises from the inside to the outside copper conductor, insulating barrier, watertight composition, nonwoven layer and the PVC of stack successivelyOuter jacket is provided with a polyvinyl chloride keriotheca between described watertight composition and nonwoven layer, and in described nothingSpin and between layer of cloth and PVC outer jacket, be provided with a setting phase-change material layers, and outside described PVC outer jacketSurface is also provided with an antiradiation coating.
Further improved: described insulating barrier comprises polyvinyl chloride layer or rubber layer.
Further improved: the thickness of described polyvinyl chloride keriotheca is 2.5-3.6mm.
Further improved: the thickness of described shaping phase-change material layer is 1.2-1.8mm.
Further improved: the thickness of described antiradiation coating is 0.8-1.3mm.
By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: the each level of the utility modelThe particular design of order is to draw through repetition test, is not simple stack, and this cable is provided with antiradiation and is coated withLayer, reaches heat insulation effect by reflected radiation, and is provided with polyvinyl chloride keriotheca, passes through shapeThe honeycomb interlayer becoming can further improve the effect of heat insulation of this cable, is also provided with a considerable amount of setting simultaneouslyPhase-change material, in the time that environment temperature is higher, phase-change material absorbs heat from the solid-state liquid state that becomes from environment; When environment temperatureSpend when lower phase-change material become from liquid heat release solid-state, thereby can play certain temperature regulating action,The excess Temperature that can effectively avoid this cable, the effect of heat insulation of this cable excellence is more suitable in inflammation such as deserts itThermally district is used.
