Abstract
The utility model discloses a high -speed EMUs are with high temperature resistant rolling stock cable, including conductor and oversheath, the conductor adopts the sixth -class tinned copper wire to make through strand hank or compound hank, and length of lay is 15 times of conductor diameter, the conductor is outer to wrap insulation core through the high temperature resistance silicone rubber insulating layer is crowded, and many insulation core strand into the cable core, be provided with the filling layer among the cable core inner gap, the outside is around the package isolation layer, the isolation layer is outward around package copper strip shielding layer, copper strip shielding layer has woven copper wire woven shield outward, copper wire woven shield is crowded package one deck oversheath outward. The utility model discloses cable insulation and oversheath adopt silicone rubber composite, and the temperature resistant grade reaches 180 DEG C, still have good mechanical property, aging resistance can and low smoke and zero halogen low toxicity fire behaviour, use on being particularly suitable for being used in the high -speed EMUs railroad locomotive vehicle that the temperature resistant grade had relatively high expectations.
Description
Technical field
This utility model belongs to field of cable technology, is specifically related to a kind of high temperature resistant cable for rolling stock of EMU.
Background technology
Operation in EMUs with lay circumstance complication, the especially CRH380A EMU of speed per hour 350km is big due to locomotive power in high-speed cruising, the high-speed cruising time is long, internal temperature drastically raises, reach as high as 180 DEG C, under such hot environment, common cable for rolling stock cannot meet service requirement, the material temperature resistant grades such as traditional crosslinked polyethylene are relatively low, be not suitable in this applications, and the fluoroplastics such as politef due to expensive and burning time release toxic gas, potential safety hazard can be brought to driving.
Utility model content
For solving above-mentioned technical problem, this utility model purpose is to provide a kind of high temperature resistant cable for rolling stock of EMU.
Scheme of the present utility model is as follows:
A kind of high temperature resistant cable for rolling stock of EMU, including conductor and oversheath, it is characterized in that, described conductor uses the 6th class tinned copper wire through stock strand or to be stranding into again, twisting pitch is 15 times of conductor diameters, extruding into insulated wire cores by high-temperature-resisting silicon rubber insulating barrier outside described conductor, many insulated wire cores are twisted into cable core；Described cable core internal clearance is provided with packed layer, the wrapped sealing coat in outside；The outer wrapped copper strip shielding layer of described sealing coat；It is woven with proof copper-wire braided screen layer outside described copper strip shielding layer；One layer of oversheath is extruded outside described proof copper-wire braided screen layer.
Described sealing coat uses that polyester belt is wrapped to be formed.
Described oversheath uses vulcanization type high-temperature-resisting silicon rubber composite.
This utility model has the following advantages and beneficial effect: compared with prior art, and the conductor of insulated wire cores of the present utility model and is stranding into through stock strand again by the 6th class tinned copper conductor, and the 6th class copper conductor monofilament is thin, and after multifilament stock twists, conductor intensity is strengthened.Insulating barrier uses high-temperature-resisting silicon rubber material, and this material resistance to elevated temperatures is good, improves the temperature resistant grade of cable.Screen layer uses the wrapped version adding proof copper-wire braided of copper strips, is greatly improved shield effectiveness.Restrictive coating uses vulcanization type high-temperature-resisting silicon rubber composite, and this material, in addition to having good resistance to elevated temperatures, also has good mechanical and physical performance, ageing-resistant performance and low-smoke zero-halogen low-toxicity fire resistance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Wherein: 1, conductor, 2, insulating barrier, 3, sealing coat, 4, copper strip shielding layer, 5, proof copper-wire braided screen layer, 6, oversheath, 7, packed layer.
Detailed description of the invention
Further illustrate of the present utility model below in conjunction with embodiment.
As shown in Figure 1, a kind of high temperature resistant cable for rolling stock of EMU, including conductor 1 and oversheath 6, described conductor 1 uses the 6th class tinned copper wire through stock strand or to be stranding into again, twisting pitch is 15 times of conductor diameters, described conductor 1 is outer extrudes into insulated wire cores by high-temperature-resisting silicon rubber insulating barrier 2, and many insulated wire cores are twisted into cable core；Described cable core internal clearance is provided with packed layer 7, the wrapped sealing coat in outside 3；The described outer wrapped copper strip shielding layer 4 of sealing coat 3；It is woven with proof copper-wire braided screen layer 5 outside described copper strip shielding layer 4；One layer of oversheath 6 is extruded outside described proof copper-wire braided screen layer 5.
Described sealing coat 3 uses that polyester belt is wrapped to be formed.
Described oversheath 6 uses vulcanization type high-temperature-resisting silicon rubber composite.
In specifically arranging, conductor 1 and is stranding into through stock strand again by the 6th class tinned copper conductor, twisting pitch is 15 times of conductor diameters, insulating barrier 2 is processed through online sulfuration by high-temperature-resisting silicon rubber material, sealing coat 3 is formed by polyester belt is wrapped, screen layer and be to be woven by copper strip shielding layer 4 and proof copper-wire braided screen layer 5 to form, oversheath 6 uses vulcanization type high-temperature-resisting silicon rubber composite to form through online vulcanization crosslinking.
Although above detailed description of the invention of the present utility model to be given detailed description and explanation; but it should be noted that; we can carry out various equivalence according to conception of the present utility model to above-mentioned embodiment and change and amendment; function produced by it still without departing from description contained spiritual time, all should be within protection domain of the present utility model.
