Abstract
The invention provides a one-step formed three-core overhead cable, comprising cable cores, conductors, insulating layers, a body and connecting sections, wherein the body is composed of three cable cores, a connecting section is arranged between two adjacent cable cores, a conductor is arranged inside each cable core, and an insulating layer is arranged outside each conductor. The production process of the cable is simple, and the cable is convenient to manufacture; a plastic extrusion mode replaces all processes after the cable is formed, so that the production process is greatly shortened, the production cost is lowered, a large amount of raw materials are saved, and the weight of the cable is effectively controlled.
Description
Technical field
The present invention relates to electricity, the essential electronic element that metal wire or metal tape are made, espespecially one-time formed three core framvesEmpty cable.
Background technology
Along with World Economics and scientific and technological development, the demand of electric wire is increasing, to its performance requirement improving, newlyEconomic situation and technical conditions under, the development of global wires and cables industry presents new trend, environment-friendly cable progressively becomes the whole worldThe development priority of cable, in view of normal cable has quite serious contaminative, in manufacture, use, offal treatment processThere will be the public hazards materials such as a large amount of dioxin, lead, cadmium, halide, developed country is fewer and feweri to its use, especially in European UnionAfter having formulated ROHS instruction, Europe, the United States, Deng state are more and more higher to the environmental requirement of used cable, and they have forbidden to useOr the non-environment-friendly cable of import, the research and development of ecological, environmental protective cable and wide-scale adoption have become international mainstream, and environment-friendly cable refers toDo not contain the heavy metal such as lead, cadmium, sexivalent chromium, mercury, do not contain bromide fire retardant, generally acknowledge that through SGS testing agency is to environmental-protecting performanceTest, meets European Union environmental protection instruction (RoSH) and higher than its index request, does not produce harmful halogen gas, does not produce corrosivityGas, when burning, fever amount is few, not the electric wire of contaminated soil.
The environment-friendly cable of prior art adopts conventionally, the drawing of copper, aluminium monofilament, monofilament annealing, strand system, insulating exruded, one-tenthCable is stranded, sheath, dress armour, outer jacket, such cable complex manufacturing technology, and processing cost is high, cable quality weight.
Summary of the invention
The invention provides one-time formed three core aerial cables for the problems referred to above, this product processes is simple, systemFacilitate, use the mode of plastic extrusion to replace the later all techniques of stranding, shortened greatly production technology, reduce and produceCost, saves a large amount of raw material, effectively the weight of control cables.
For addressing the above problem, the invention provides one-time formed three core aerial cables, comprise cable core, conductor, absolutelyEdge layer, body, linkage section, is characterized in that: body is made up of three cables core, the company of being provided with between two adjacent cables coreThe section of connecing, cable core inside is provided with conductor, and conductor outer setting has insulating barrier.
As a further improvement on the present invention, three cable core centers of circle are equilateral triangle or straight line.
As a further improvement on the present invention, described insulating barrier is the cross-linked polyolefin of 1 to 3 millimeters thick.
As a further improvement on the present invention, described insulating barrier outer surface is provided with acrylonitrile-butadiene rubber layer.
Operation principle:
Product of the present invention is provided with rational layout designs, can effectively reduce the processing technology of three-core cable, by onceProperty expressing technique with regard to stranding, effectively shorten the technological process of production of cable, multiple on conductor by direct expressing techniqueClose insulating barrier and linkage section, have production efficiency high, good product quality, effectively reduces the weight of product, and material adopts crosslinkedPolyolefin there is good anti-flaming thermal-insulation effect, can effectively prevent the secondary harm that cable fire causes, can be effectivelyReduce electromagnetic radiation, simultaneously insulating barrier outer surface parcel one deck acrylonitrile-butadiene rubber layer can effectively utilize acrylonitrile-butadiene rubber oil resistant,The performance of ageing-resistant, resistance to weather, makes cable life longer, uses more stable.
The present invention compared with prior art has following beneficial effect:
1, product of the present invention is provided with rational layout designs, can effectively reduce the processing technology of three-core cable, by oneThe expressing technique of inferior property, with regard to stranding, effectively shortens the technological process of production of cable, by direct expressing technique on conductorComposite insulation layer and linkage section, have production efficiency high, and good product quality effectively reduces the weight of product, and material adopts to be handed overThe polyolefin of connection has good anti-flaming thermal-insulation effect, can effectively prevent the secondary harm that cable fire causes, can be effectiveReduction electromagnetic radiation;
2, simultaneously insulating barrier outer surface parcel one deck acrylonitrile-butadiene rubber layer can effectively utilize acrylonitrile-butadiene rubber oil resistant, ageing-resistant,The performance of resistance to weather, makes cable life longer, uses more stable.
