Abstract
The utility model discloses a fire-proof and environment-friendly power cable, which comprises cable conductor wire cores. Fire-proof layers are arranged on the outside of the cable conductor cores. Insulation layers extrudes the fire-proof layers and the cable conductor cores become the insulated wire cores. A cable core is stranded by a plurality of insulated wire cores. Fillers are filled in the gap inside the cable core. A wrapping layer, a shielding layer and a coating layer are sequentially and concentrically wrap on the cable core. The power cable utilizes copper clad aluminum conducting materials, thereby effectively remedying the shortcomings of the application of copper conductors and aluminium conductors on the electric wire and cable engineer, for example, the pure copper conductors have high density, are expensive, are not easy to be laid, are deficient in domestic resources and the like; the aluminum conductors have low electric conductivity, bad welding performance, easy oxydic surface, large contact resistance and the like. The fire-proof and environment-friendly power cable has the advantages that the power cable has good conductivity, low weight and low cost, is easy to weld, convenient to be laid, fire proof and environment-friendly, has shielding interference performance and the like.
Description
Technical field
The utility model relates to a kind of cable, especially a kind of fire-resistant environmental-friendly power cable that adopts novel conductor.
Background technology
Along with the high speed development of China's economic construction, every profession and trade continues to increase the demand of electric power, and the market space of wires and cables industry is huge.But the copper, the aluminium conductor that account for main component in the electric wire product structure exist the shortcoming that self is difficult to overcome.As: the density of pure cu conductor big (8.89g/cm3), china natural resources are deficient; The conductance of fine aluminium conductor relatively poor (IACS=61%), mechanical strength is on the low side, welding performance is poor, contact resistance is big, more in air, very easily generate aluminum oxide film with insulation property because of the fine aluminium conductor, cause electric current in the stranded conductor to make the hand of spiral and flow, the AC resistance of conductor is increased, reduce the ampacity of cable along the aluminium single line.Copper-clad aluminum conductor promptly is that fine copper and pure aluminum material are carried out the science transformation, make full use of their advantage separately, a kind of novel conductor material that creates, it has effectively remedied the shortcoming that fine copper, fine aluminium conductor are used on engineering, on the electric wire engineering, promote the use of copper clad aluminum conductor, help the comprehensive utilization of China's nonferrous metal resource, can reduce product cost significantly, but the example of using on market at present is few.
The utility model content
The technical problems to be solved in the utility model provides the fire-resistant environmental-friendly power cable of a kind of conductor, has to save the cables manufacturing cost, and has functions such as fire-resistant, shielding interference, environmental protection.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of fire-resistant environmental-friendly power cable, comprise the cable conduction core, described cable conduction core is provided with flame retardant coating outward, outside flame retardant coating, become insulated wire cores behind the extruded insulation layer, make cable core by some eradication edge core strands again, the space in cable core is filled with filler, and described cable core twines belting layer, screen and restrictive coating outward successively with one heart.
Cable conduction core described in the utility model is made of some copper cover aluminum single line strand systems.

The utility model compared with prior art, have conduct electricity very well, easily welding, in light weight, be convenient to lay and characteristics such as cost is low, and have fire-resistant, shielding is disturbed, environmental-protecting performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of fire-resistant environmental-friendly power cable that adopts novel conductor of the utility model, comprise cable conduction core 7, cable conduction core 7 outer overlapping wrapped fire-resistant isinglass belts become flame retardant coating 6, flame retardant coating 6 outer extruded insulation layers 5 constitute insulated wire cores, adopt two cores, three cores, four-core or five core insulation cores 5 to twist with one heart and make cable core, the space in the cable core is filled with filler 4, and cable core is wound with belting layer 3, screen 2 and restrictive coating 1 outward successively with one heart.Wherein, cable conduction core 7 is made of many copper cover aluminum single line strand systems, and the outer wrapped fire-resistant isinglass belt of conductor wire core constitutes flame retardant coating, and insulating barrier adopts the crosslinked polyethylene material to extrude, filler 4 adopts glass silk fire proofing to fill, and belting layer 3 adopts the glass fiber flame retardant band overlapping wrapped.Screen 2 adopts the overlapping wrapped formation of copper strips, and restrictive coating 1 is for extruding the environment-protective halogen-free low-smoke flame-retardant restrictive coating.
The utility model adopts the copper clad aluminum conductor material, effectively remedied the shortcoming that copper, aluminium conductor are used on the electric wire engineering, as: big, the domestic scarcity of resources of the density of pure cu conductor, cost an arm and a leg, be difficult for laying etc., the conductance of aluminium conductor is low, welding performance is poor, easily oxidation of surface, contact resistance are big etc.The utility model cable have conduct electricity very well, easily welding, in light weight, be convenient to lay and characteristics such as cost is low, and have fire-resistant, shielding is disturbed, environmental-protecting performance.
The utility model provides a kind of thinking and implementation method of fire-resistant environmental-friendly power cable; concrete application approach is a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection range of the present utility model.
