Abstract
The utility model relates to the technical field of telecommunication cable, especially to a composite shielded copper-coated aluminium magnesium alloy wire control cable which comprises a plurality of core wires. Each core wire is coated with an insulating layer which is coated with a shielding layer. The outermost layer of the shielding layer is a protective jacket. The shielding layer is formed by weaving copper-coated aluminium magnesium alloy wires. According to the utility model, the copper-coated aluminium magnesium alloy wire is used as a new copper-coated aluminium material, and the core wire is prepared from aluminium magnesium alloy. In comparison with wires prepared from common copper-coated aluminium, strength of the copper-coated aluminium magnesium alloy wire is greatly raised and reaches 240MPa such that the disadvantage that copper-coated aluminium wires have low strength and are easy to break is solved and insufficiencies of mechanical properties of the copper-coated aluminium wires are made up. By the adoption of the copper-coated aluminium magnesium alloy wires woven to produce the shielding layer, excellent electrical conductivity of copper and aluminium magnesium alloy wire's advantages of light weight and good shielding performance are integrated. Therefore, the copper wire material of the shielding layer is greatly saved, and cost of raw materials can be substantially saved.
Description
Technical field
The utility model relates to the telecommunication cable technical field, especially a kind of shielded type composite CCAM control cables.
Background technology
Along with the economic develop rapidly of China, improving constantly of living standards of the people, economic construction and people's daily life are to the underload power line, the Cable TV Signal Transmission wire, large capacity communication network signal transmission wire, the control signal cable, light body vehicle cable, welding cable, urgent removal cable, the television set excitation coil, deflecting coil, the ballast coil, video/audio wire, automotive wire bundle, the demands such as cable shield litzendraht wire and enamelled wire winding increase very fast, require conductor material to have good electric conductivity, signal transmission performance, mechanical property and mechanical performance.
Connecting line as control between protection system of electric power transfer and each electric appliances, instrument and the automatics, monitoring interlock circuit and protection circuit; the main braid shielded type cable that adopts, its braid shielded layer material mainly adopts circular copper wire and tin-plating round copper wire.As everyone knows, not only density is large for pure copper material, production cost is high, and copper resource-constrained, and can not regenerate, in order to address this problem most of copper-clad aluminum conductor that adopts, copper-clad aluminum conductor diameter intensity when 0.5mm is following is low, the bad mechanical property that easily breaks, and range of application is narrow, is difficult to meet the high strength requirement of electronic communication shielded alloy wire.
The utility model content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of shielded type composite CCAM control cables.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of shielded type composite CCAM control cables, comprise the complex root heart yearn, and described heart yearn outside has polyethylene foamed insulating barrier, good insulating.The polyethylene foamed insulating barrier has screen outward, and the screen outside is coated with the polyvinyl chloride flame-retardant sheath, can play good flame retardant effect.Described screen is formed by the copper cladded aluminum-magnesium alloy wire braiding, and described heart yearn is the almag heart yearn, has the intensity height, is difficult for the advantage of broken string.。
Further, the braiding structure of described copper cladded aluminum-magnesium alloy wire is for having 12 bundles, 10 of every bundles, every 0.1mm, lay of braiding 18mm, the use amount of effectively having saved litzendraht wire.
The beneficial effects of the utility model are, CCAM of the present utility model is as the copper cover aluminum new material, its heart yearn adopts almag, intensity is compared the ordinary copper alclad significantly lifting, reach 240 MPa, solve the shortcomings such as copper-clad aluminum conductor intensity is low, easy broken string, remedied the deficiency of its mechanical performance; Employing copper cladded aluminum-magnesium alloy wire braiding making screen has been gathered the good electric conductivity of copper and aluminum-magnesium alloy wire is lightweight, the advantage of advantages of good shielding performance, saves in a large number the materials of screen copper cash, and cost can significantly save material.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. heart yearns among the figure, 2. polyethylene foamed insulating barrier, 3. screen, 4. polyvinyl chloride flame-retardant sheath.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shielded type composite CCAM control cables as shown in Figure 1 comprises complex root heart yearn 1, and heart yearn 1 outside has polyethylene foamed insulating barrier 2, good insulating.Have screen 3 outside the polyethylene foamed insulating barrier 2, screen 3 outsides are coated with polyvinyl chloride flame-retardant sheath 4, can play good flame retardant effect.Screen 3 is formed by copper cladded aluminum-magnesium alloy wire braiding, and the braiding structure of copper cladded aluminum-magnesium alloy wire is for having 12 to restraint, 10 of every bundles, and every 0.1mm, lay of braiding 18mm,, the use amount of effectively having saved litzendraht wire.Heart yearn 1 material is almag, has the intensity height, is difficult for the advantage of broken string.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
