Description
Technical field
The utility model relates to a kind of bus, particularly a kind of tube type bus.
Background technology
In the last few years, after the large-scale place of public amusement of domestic a few family, chemical industry, colliery, mall fire cause painful people's life and property heavy losses, people had had more deep understanding to fire-fighting, fire safety.Along with the sharp increase of urban population, skyscraper, hotel, large supermarket, hospital, station, airport constantly increase, the construction of subway, tunnel traffic, and large-scale Public Physical Education, public place of entertainment, public transit facility increase, the importance of fire-fighting, fire safety shows especially out.How in the case of fire, ensure the unimpeded of electric power and communication within a certain period of time, win valuable rescue time to greatest extent, reduce the injures and deaths of personnel and the loss of lives and properties.
Utility model content
The purpose of this utility model is to provide a kind of cast flame retardant bus, strengthens the insulation of bus, acidproof, alkaline-resisting, heatproof, ageing-resistant performance, extends bus useful life.
The purpose of this utility model is achieved in that a kind of cast flame retardant bus; comprise center conductor; the periphery of center conductor is enclosed with first set tube layer; the periphery of first set tube layer is surrounded with insulating barrier; the periphery of insulating barrier is enclosed with the second casing layer; the periphery of the second casing layer is surrounded with conductive earthing screen, and the periphery of conductive earthing screen is enclosed with the 3rd casing layer, and the periphery of the 3rd casing layer is coated with protective sleeve.
Limit further as the utility model, described first set tube layer, the second casing layer, the 3rd casing layer and protective sleeve are the thermal contraction sheath that polyolefine material is made.
Limit further as the utility model, described insulating barrier adopts polytetrafluoroethylmaterial material to make.
Compared with prior art, the beneficial effects of the utility model are, the periphery of the utility model by using the thermal contraction sheath made of polyolefine material to be located at conductor as the insulating barrier spacer sleeve that casing layer and polytetrafluoroethylmaterial material are made, enhance fire-retardant, the insulation property of bus, the sheath of thermal contraction simultaneously strengthens the elasticity of bus, extends the useful life of bus.The utility model can be used in the electrical transmission of public arena.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 center conductor, 2 first set tube layer, 3 insulating barriers, 4 second casing layers, 5 conductive earthing screens, 6 the 3rd casing layers, 7 protective sleeves.
Embodiment
A kind of cast flame retardant bus as shown in Figure 1, comprise center conductor 1, the periphery of center conductor 1 is enclosed with first set tube layer 2, the periphery of first set tube layer 2 is surrounded with insulating barrier 3, the periphery of insulating barrier 3 is enclosed with the second casing layer 4, the periphery of the second casing layer 4 is surrounded with conductive earthing screen 5, the periphery of conductive earthing screen 5 is enclosed with the 3rd casing layer 6, the periphery of the 3rd casing layer 6 is coated with protective sleeve 7, first set tube layer 2, second casing layer 4, 3rd casing layer 6 and protective sleeve 7 are the thermal contraction sheath that polyolefine material is made, insulating barrier 3 adopts polytetrafluoroethylmaterial material to make.
Thermal contraction sheath has excellent fire-retardant, insulation property, very soft flexible, shrinkage temperature is low, shrink fast, the connection of electric wire, wire end process, solder joint protection, wire harness mark, the insulation protection of resistance capacitance, metal bar or the anti-corrosion protection of tubing, the protection etc. of antenna can be widely used in; The utility model the 2nd layer, the 4th layer, the 6th layer, the 7th Rotating fields material all adopts polyolefin material to be the pyrocondensation protective sleeve 7 of main material, has high-temperature shrinkage, soft fire-retardant, insulation corrosion protection function; This material will experience glassy state-elastomeric state from low to high along with temperature, and during glassy state, performance is close to plastics, and during elastomeric state, performance is close to rubber.Heat-shrink tube material therefor is at room temperature glassy state, becomes elastomeric state after heating; During production, heat-shrink tube is heated to elastomeric state, imposed load makes it expand, and cools fast when keeping expansion, make it enter glassy state, this state has just been fixed, in use a heating, it will become elastomeric state again, but at this moment load without, it will bounce back.
3rd layer is polytetrafluoroethylene floor, and polytetrafluoroethylene has high temperature resistant (using working temperature to reach 250 DEG C), and low temperature resistant (have good mechanical tenacity, namely-196 DEG C are dropped temperature to, also the percentage elongation of 5% can be kept), anti-flammability (just going out from fire), corrosion-resistant (to most of chemicals and solvent, show inertia, energy strong alkali-acid resistance, water and various organic solvent), weather (having aging life-span best in plastics), high lubrication (being coefficient of friction the lowest in solid material), do not adhere to (is surface tension minimum in solid material, do not adhere to any material), nonhazardous (has physiological inertia, implant for a long time as artificial blood vessel and internal organs and have no adverse reaction), electrical insulating property (1500 volts of high-tension electricities can be resisted).
The utility model is not limited to above-described embodiment; on the basis of technical scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in protection range of the present utility model.
