Abstract
The utility model relates to a high flame retardant and fire resistant cable of 1500 V, which can be extensively used for such important projects as rail transportation, nuclear power plants and other energy supply systems of 1500 V. The high flame retardant and fire resistant cable of 1500 V is characterized in that a conductor, an ultra-temperature fire resistant tape, cross-linked polyethylene (XLPE) insulation, a low smoke zero halogen (LSOH) glass fiber cloth tape, a longitudinally covered Al-plastic composite tape, a high oxygen barrier flame retardant sheath, an LSOH glass fiber cloth tape and an LSOH outer sheath are included, wherein the conductor is arranged at the innermost layer; and the ultra-temperature fire resistant tape, the XLPE insulation, the LSOH glass fiber cloth tape, the longitudinally covered Al-plastic composite tape, the high oxygen barrier flame retardant sheath, the LSOH glass fiber cloth tape and the LSOH outer sheath are arranged outside the conductor in sequence from inside to outside in a covering manner. The utility model has the advantages of reasonable structural design, high flame retardancy, fire resistance, low smoke and toxicity, waterproofness, rat resistance, termite resistance and environment friendliness.
Description
Technical field
The utility model relates to a kind of 1500V high flame retardant fire-resisting cable, can be widely used in track traffic, nuclear power station, etc. key projects such as other 1500V electric power system.
Background technology
The fire-resisting cable of voltage levels is less in the market, and the ubiquitous problem of market upper part voltage levels fire-resisting cable: 1, high flame retardant, fire resistance have satisfied, and withstand voltage being difficult to passed through; 2, withstand voltage having passed through, high flame retardant, fire resistance have also been given a discount; Or high flame retardant, fire resistance, withstand voltage having passed through, low cigarette, the low toxic and environment-friendly performance of cable do not satisfy the Electrical Safety requirement.
Common fire-resisting cable all be by outside conductor around outside the fire-resistant fire resistance that satisfies cable that brings, but when the withstand voltage of cable is high more, the decreasing insulating of fire-resistant band has reduced the withstand voltage level of finished cable.
Existing voltage levels cable does not possess waterproof, protection against rodents, anti-ant performance.The general rainfall of southern area is big, the level of ground water height, and to the waterproof requirement height of cable, and low smoke and zero halogen material waterproofing poor performance, and ant and mouse also are the major hidden dangers of cable security.
Summary of the invention
Technical problem to be solved in the utility model provides the 1500V high flame retardant fire-resisting cable of a kind of reasonable in design, high flame retardant, fire-resistant, low cigarette, low toxicity, waterproof, protection against rodents, anti-ant, environmental protection.
It is this 1500V high flame retardant fire-resisting cable that the utility model solves the problems of the technologies described above the technical scheme that is adopted, be characterized in: by conductor, the fire-resistant band of extra-high-speed temperature, crosslinked polyetylene insulated, low smoke and zero halogen glass fiber strap, vertical alclad plastic composite strip, the fire-retardant sheath of high oxygen barrier, low smoke and zero halogen glass fiber strap, the low smoke and zero halogen oversheath is formed, described conductor is arranged on the inside, the fire-resistant band of described extra-high-speed temperature, crosslinked polyetylene insulated, low smoke and zero halogen glass fiber strap, vertical alclad plastic composite strip, the fire-retardant sheath of high oxygen barrier, low smoke and zero halogen glass fiber strap, the low smoke and zero halogen oversheath is wrapped in outside the conductor from inside to outside successively.
Be provided with the protection against rodents armour between the fire-retardant sheath of high oxygen barrier described in the utility model, the low smoke and zero halogen glass fiber strap.
Conductor described in the utility model adopts circular compact conductor.
The utility model is compared with prior art and had the following advantages and effect: structure of the present utility model has guaranteed high flame retardant, the fire resistance of cable under 1500V electric pressure environment, has improved the security reliability that electric power is carried.Cable has, high flame retardant, fire-resistant, waterproof, protection against rodents, anti-ant, antiultraviolet, anti-Japanese illumination aging performance.By adopting circular compact conductor, improve conductive surface evenness and fineness.Employing is indulged the bag metal tape and is extruded high oxygen barrier material inner sheath continuously and comprehensively form watertight composition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment 1: as shown in Figure 1, present embodiment by conductor 1, extra-high-speed temperature fire-resistantly be with 2, crosslinked polyetylene insulated 3, low smoke and zero halogen glass fiber strap 4, vertical alclad plastic composite strip 5, the fire-retardant sheath 6 of high oxygen barrier, protection against rodents armour 7, low smoke and zero halogen glass fiber strap 8, low smoke and zero halogen oversheath 9 form, conductor 1 is circular compact conductor, improves conductive surface evenness and fineness.The extra-high-speed temperature fire-resistant with 2, crosslinked polyetylene insulated 3, low smoke and zero halogen glass fiber strap 4, vertical alclad plastic composite strip 5, the fire-retardant sheath 6 of high oxygen barrier, protection against rodents armour 7, low smoke and zero halogen glass fiber strap 8, low smoke and zero halogen oversheath 9 be wrapped in the outside of conductor 1 from inside to outside successively.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection range of the utility model patent according to the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection range of the present utility model.
