Abstract
The utility model discloses an irradiation locomotive cable. The cable comprises a conductor, an insulating layer and a sheath layer. The conductor passes through and is extruded in the insulating layer. The sheath layer is extruded out of the insulating layer. Through carrying out irradiation crosslinking on the insulating layer and the sheath layer, performance of the cable, such as stretch resistance, ageing resistance, heat extension, high temperature resistance, oil resistance and the like, is greatly increased. After testing, a result indicates that all the performance accords with a national standard. After the irradiation crosslinking is performed on the insulating layer and the sheath layer, an elongation rate under a load reaches 20%-100% and a permanent deformation rate reaches below 20%.
Description
Technical field
The utility model relates to the cable technology field, especially a kind of irradiation locomotive cable, the dynamic transfer system that is used for equipment such as rail system rolling stock, subway, light rail, control system and signal system are transmitted, and are applicable to the electric equipment cable of rated voltage 3kV and following all kinds rolling stock inside.
Background technology
Along with the urban rail transit in China construction is advanced by leaps and bounds, the railway system had had breakthrough development, particularly high-speed railway in recent years; During " 12 ", China railways capital construction gross investment is about 3.5 trillion yuan, higher by 70% than Eleventh Five-Year Plan, high ferro will inevitably continue to greatly develop as the principal direction of following passenger traffic, the emphasis of 2013-2015 country high ferro construction will be western part and southwest, and Xu Lan high ferro project, Borland Line for Passenger Transportation, Lanzhou-Xinjiang high ferro project all go into operation at present.
Ac rated voltage 3kV and following locomotive cable are as the significant components that is applied to occasions such as vehicular traffic distribution system, control system, signal system equipment, and the particularity of laying environment is an acid test to cable.Poor because of the environmental condition on the locomotive, the distribution cable of locomotive inside usually will contact greasy dirt and have fuel oil, lubricated wet goods organic pollution, and regional area is soaked by sewage; Have a large amount of dust in most of environment, solid contaminant such as metal break flour also may exist in the air because this conductor of electricity is extruded in this insulating barrier, and this restrictive coating is extruded in outside this insulating barrier.Hit the air pollutants such as ozone, nitric oxide of generation, the chemical composition of running space is extremely complicated; For guaranteeing the electrical insulating property of whole locomotive, just correspondingly require distribution cable to have excellent electric insulation, oil resistance, high temperature resistant, decay resistance, also necessity has good LSOH anti-flaming performance and softness simultaneously, so cable manufacturing technique requirent harshness, processing is big.
According to GB/T 12528-2008 " ac rated voltage 3kV and following rail traffic vehicles cable " standard code, rail traffic vehicles must be ethylene-propylene rubber with cable insulation material, sheath material must be chlorosulfonated polyethylene rubber or other suitable synthetic elastomer, for electric, the mechanical performance that makes insulation, sheath satisfies the national standard requirement, this just necessarily requires CABLE MATERIALS is carried out crosslinking process, the crosslinking process process is that the linearity molecular structure material is passed through specific processing mode, makes it form the crosslinked polyethylene of netted minute line structure of build.Under the prerequisite that keeps its original superior electrical performance, improved actual serviceability widely, steam continuous vulcanization technology is adopted in the traditional second third insulated cable production, and advantage is efficient height, excellent electrical properties, and shortcoming is that heat resistance, oil resistance, decay resistance are not ideal enough.
The utility model content
The utility model proposes a kind of irradiation locomotive cable at the deficiencies in the prior art, has characteristics such as excellent oil resistance, high temperature resistant, corrosion resistance.
In order to realize above-mentioned utility model purpose, the utility model provides following technical scheme: a kind of irradiation locomotive cable, comprise conductor, insulating barrier and restrictive coating, and this conductor is extruded in this insulating barrier, and this restrictive coating is extruded in outside this insulating barrier.
The zinc-plated flexible conductor of 5 classes that conductor adopts GB/T 3956-2008 to require; Insulated tube adopts irradiation crosslinking type ethylene-propylene rubber mixture material, has good mechanical property, the characteristics that electrical property is excellent; Sheath material adopts irradiation crosslinking type chlorosulfonated polyethylene rubber mixture, and this material is usually used in the rubber cover class flexible cable of special purpose, and crosslinked back tensile strength can reach 10.8-11.5 N/mm
2, material fuel oil resistance, anti-mineral oil and tool flame-retarding characteristic.
Compared with prior art, the utlity model has following advantage: by the cross-linking radiation to insulating barrier, restrictive coating, to irradiation locomotive cable carried out stretch-proof, ageing-resistant, heat is extended, the test of main performance such as high temperature resistant, the result shows that all properties all meets national standard; Insulation and sheath material are behind cross-linking radiation, and the percentage elongation under the load reaches 20%-100%, and permanent deformation reaches below 20%.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail, the description of this part only is exemplary and explanatory, should any restriction not arranged to protection range of the present utility model.
A kind of irradiation locomotive cable as shown in Figure 1 comprises conductor 1, insulating barrier 2 and restrictive coating 3, and this conductor 1 is extruded in this insulating barrier 2, and this restrictive coating 3 is extruded in outside this insulating barrier 2.
Conductor 1 adopts and meets the 5th kind of tinned conductor that GB/T 3956-2008 requires.Insulating barrier 2 extrudes and adopts Φ 90 plastic extruding machines to extrude.Adopt on the AB-2.5MeV high frequency high voltage electron accelerator and finish insulating barrier cross-linking radiation operation, high pressure 2.0MV, sweep away electric current 3.0A, the vertical electric current 0.6A that sweeps, adopt big bundle winding displacement down, by adjusting corresponding speed and tracking and monitoring, comparing data shows repeatedly, when corresponding speed was 60m/min, heat was extended and aged properties can satisfy standard-required.Sheath 3 extrudes also and extrudes by Φ 90 plastic extruding machines, and AB-2.5MeV high frequency high voltage electron accelerator irradiation parameters is high pressure 2.0MV, sweeps away electric current 3.0A, and the vertical electric current 0.6A that sweeps adopts big bundle winding displacement down, 30m/min.
In July, 2012 so far, the DCEH/3-100 1500V 25(A that centering iron is 18 innings) during rail traffic vehicles employing the utility model cable is followed the tracks of and is followed up a case by regular visits to, confirm according to client's feedback information and field observation, mineral in the cable environment for use, mechanical greasy dirt are obvious, the cable operation is normal, jacket surface does not have cracking or the blow-up problem occurs, and the cable outward appearance is good.
