The utility model discloses a highly flexible power cable, which sequentially comprises a conductor, an insulating layer and a sheath layer from the inside to the outside, and the conductor adopts a soft combination structure of extra-fine copper wire bundle twisting and multiple twisting. In the utility model, since the conductor adopts a soft combination structure of ultra-fine copper wire bundle twisting and multiple twisting, the highly flexible power cable can have better flexibility than the previous power cables in special mobile occasions, and a higher voltage than the previous weak current flexible cables grade. The insulation and sheath materials used have low-smoke, halogen-free, extremely low toxicity, radiation resistance, high and low temperature resistance and wear resistance, and can effectively adapt to wide temperature changes from high to low, radiation resistance, and photoaging resistance to high-intensity ultraviolet rays. , The toxic damage to the human body is extremely slight. When the line has high frequency and high temperature difference changes and radiation, it has no effect on the electrical performance of the cable line itself; when there is a fire or other accident, the gas toxicity produced has little damage to the human body.
Description
Technical field
The utility model relates to a kind of power cable, the high flexibility power cable with height softness that especially a kind of low-voltage power supply system equipment uses.
Background technology
At present, electric power supply system equipment connection has both at home and abroad reached quite high level with power cable, but the power cable of extraordinary mobile occasion low-voltage power supply system does not but obtain enough attention.Standard GB/T3956 " conductor of cable " regulation, the cable conductor structural of China is divided into 4 kinds altogether, is respectively the 1st kind, and the 2nd kind, the 5th kind and the 6th kind is more and more softer.Power cable standard GB/T12706 regulation, the conductor structure of power cable can be the 1st kind, the 2nd kind and the 5th kind of structure, does not have unit to accomplish than the 5th kind of also soft power cable of conductor structure.Usually adopted general plastics or rubber power cable in the past.These cables twist conductor by the stranded of routine or bundle and the plastic, rubber material constitutes.Common plastics and rubber power cable are in the occasion that softness is had relatively high expectations, conductor flexibility deficiency, can not adapt to harsh and unforgiving environments conditions such as high height above sea level, high intensity ultraviolet beta radiation, and performances such as cable is high temperature resistant, low temperature resistant and wear-resisting can not be simultaneously effectively satisfied, makes cable that the problem appearance of shortening in insulation and sheath material cracking, useful life be arranged within a short period of time.
The utility model content
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and a kind of high flexibility power cable is provided.
Technical scheme: the utility model discloses a kind of high flexibility power cable, comprise successively that from inside to outside conductor, insulating barrier and restrictive coating, described conductor adopt the soft combining structure of superfine copper wire bundle strand.
In the utility model, the superfine brass wire diameter of described conductor is below the 0.10mm.
In the utility model, preferably, after being twisted by superfine copper wire bundle, described conductor is twisted into the structure more than two again.Can on the basis that guarantees the cable flexibility, strengthen the toughness of conductor thus.
In the utility model, preferably, described insulating barrier and restrictive coating are to have a low smoke and zero halogen utmost point hypotoxicity, the polyolefine material of radiation hardness, high-low temperature resistant and performance such as wear-resisting.With insulation and sheath material have low smoke and zero halogen utmost point hypotoxicity, radiation hardness, high-low temperature resistant and anti-wear performance can effectively adapt to difference variation, the radioresistance of broad fluctuated, the light aging of anti-high-intensity ultraviolet, and be extremely slight etc. to the toxicity infringement of human body.When higher difference variation of high-frequency and radiation appear in circuit, the electrical property of cable line itself is had no effect; The gas toxicity that produces when accident such as fire occurring is very little to the human body infringement.
Beneficial effect: the soft combining structure that adopts superfine copper wire bundle strand and multiple strand in the utility model owing to conductor, this high flexibility power cable conductor has more flexibility than the 5th class conductor again, and cable is had than power cable was better flexible in the past in the mobile occasion of special type.The insulation and the sheath material that adopt have low smoke and zero halogen utmost point hypotoxicity, and radiation hardness, high-low temperature resistant and anti-wear performance can effectively adapt to difference variation, the radioresistance of broad fluctuated, the light aging of anti-high-intensity ultraviolet, and be extremely slight to the toxicity infringement of human body.When higher difference variation of high-frequency and radiation appear in circuit, the electrical property of cable line itself is had no effect; The gas toxicity that produces when accident such as fire occurring is very little to the human body infringement.This construction of cable and performance have higher advantage than common power cable and light current flexible cable, integrate multiple performance, help the safe operation of extraordinary mobile occasion high flexibility power cable.
Description of drawings
Fig. 1 is the cross-section of cable structural representation of a kind of embodiment of the present utility model.
Fig. 2 is the cross-section of cable structural representation of another kind of embodiment of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Embodiment 1: as shown in Figure 1, the high flexibility power cable described in the embodiment comprises conductor 1, insulating barrier 2 and restrictive coating 3 from inside to outside successively.Conductor 1 employing diameter is that the superfine copper wire bundle of 0.10mm is twisted into the high flexibility conductors that combined by 7 bursts of multiple strands again behind the thigh, and conductor 1 outer extruded insulation 2 is extruded with the restrictive coating 3 that polyolefine material constitutes at last.
Embodiment 2: as shown in Figure 2, the high flexibility power cable described in the embodiment comprises conductor 1, insulating barrier 2 and restrictive coating 3 from inside to outside successively.Conductor 1 employing diameter is that the superfine copper wire bundle of 0.05mm is twisted into the high flexibility conductor that forms behind the thigh, and conductor 1 outer extruded insulation 2 is extruded with the restrictive coating 3 that polyolefine material constitutes at last.
This structure can make cable have common power cable be beyond one's reach the height flexibility.Can effectively suppress simultaneously ultraviolet radiation, high-concentrated ozone erosion, fire, wear-resisting and grease injury etc. cable is produced destructive behavior.Cable still can keep flexible preferably and other mechanical and physical performance under mobile occasion and extremely low or higher temperature, the normal operation to low-voltage power supply system equipment does not produce any interference.
The utility model provides a kind of thinking and method of high flexibility power cable; the method and the approach of this technical scheme of specific implementation are 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 improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
