Abstract
The invention discloses a cable, which comprises four wire core groups, wherein each wire core group comprises two wire core conductors with insulating layers; a silica gel layer is arranged among the four wire core groups; a glass fiber tape is arranged at the peripheries of the four wire core groups; a metal shielding layer is arranged at the periphery of the glass fiber tape; a sheath is arranged at the periphery of the metal shielding layer and is made of a polytetrafluoroethylene material; and the average thickness of the sheath should not be smaller than 3mm. According to the cable, the insulating property is improved; and the cable has high-temperature-resistant characteristics, so that the service lifetime of the cable is prolonged; the application range of the cable is expanded; and the cable also has the characteristics of good shielding properties, high flame retardant capability, energy conservation and environmental protection.
Description
Technical field
The present invention relates to a kind of cable.
Background technology
China's tradition and existing middle pressure crosslinked cable, have three aspect Shortcomings at least, can not meet China's electric railway, the needs of high speed development.The first, electric pressure, the electric pressure U of electric railway traction power supply system
ofor 27.5kV, and tradition and existing middle pressure crosslinked cable, ceiling voltage is 26/35kV, U
ofor 26kV, obviously can not meet.The second, block-water performance aspect, China is the country on many mountains, and in high-speed railway, cavern tunnel everywhere, and in not only many but also long cavern tunnel, environment not only humidity but also complicated, cable needs to have the performance blocked water.Three, fire resistance, traditional middle pressure crosslinked cable, does not have this model of flame retardant cable.
In addition, because sheath and insulating barrier adopt traditional material to make, there is fire retardancy difference and the less-than-ideal defect of insulation effect, thus in process in routine use, with certain potential safety hazard, directly threaten the personal safety of the people, therefore need should solve in time above-mentioned defect.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the invention is to provide a kind of good insulation preformance, the cable that high temperature resistant, fire retardancy is strong.
To achieve these goals, the present invention adopts following technical scheme:
A kind of cable, include four core groups, each core group is made up of two core conductors with insulating barrier, layer of silica gel is provided with between described four core groups, the outer of four core groups is arranged with glass fiber band, and the outer of glass fiber band is arranged with metal screen layer, and the outer of metal screen layer is arranged with sheath, described sheath is made up of polytetrafluoroethylmaterial material, and its average thickness should be not less than 3mm.
Be provided with non-absorbent material between described metal screen layer and sheath and make separator.
Described metal screen layer adopts tinned copper wire woven shield.
Beneficial effect of the present invention: due to the sheath adopting polytetrafluoroethylmaterial material to make, not only increase insulation property, but also there is resistant to elevated temperatures characteristic, thus extend the useful life of cable, widened the range of application of cable; The present invention also has that advantages of good shielding performance, fire retardancy are strong, the feature of energy-conserving and environment-protective.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail, but the embodiment in accompanying drawing does not form any limitation of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, can also obtain other accompanying drawing according to the following drawings, but the embodiment in accompanying drawing does not form any limitation of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the following drawings:
Fig. 1 is structural representation of the present invention.
In figure: 1, core; 2, insulating barrier; 3, core conductor; 4, layer of silica gel; 5, glass fiber band; 6, metal screen layer; 7, non-absorbent material makes separator; 8, sheath.
Embodiment
As shown in Figure 1, a kind of cable, include four core groups 1, each core group 1 is made up of two core conductors 3 with the insulating barrier 2 of flame retarding polyether type thermoplastic polyurethane elastomeric material, layer of silica gel 4 is provided with between described four core groups 1, the outer of four core groups 1 is arranged with glass fiber band 5, the outer of glass fiber band 5 is arranged with metal screen layer 6, the outer non-absorbent material that is arranged with of metal screen layer 6 makes separator 7, and non-absorbent material is made the outer of separator 7 and is arranged with the sheath 8 be made up of polytetrafluoroethylmaterial material.Metal screen layer 6 adopts tinned copper wire woven shield.
The characteristic of polytetrafluoroethylene:
1, excellent electrical insulation capability: specific insulation > 10
17Ω .cm, breakdown strength is high, and can reach 200kV/mm, arc resistance is excellent;
2, thermal endurance, cold resistance: use continuously in the temperature range of-85 DEG C ~ 200 DEG C;
3, chemical-resistant stability is excellent;
4, resistance to antioxygenic property is excellent;
5, higher mechanical strength.
Set forth a lot of detail in description above so that fully understand the present invention, but the present invention can also adopt other to be different from other modes described here and implement, and therefore, can not be interpreted as limiting the scope of the invention.
