Description
Technical field
The utility model relates to a kind of cold-resistant flexible frequency-changing cable, belongs to electric wire field.
Background technology
The cable of at least two stranded similar ropes normally often organized by cable by several or several groups of wires, often organize mutually insulated between wire, and be often twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Cable has power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, aluminium alloy cable etc.They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc.
Since the nineties in 20th century, cable industry is described as city " nerve " and " blood vessel ", and bearing is the supporting function of all trades and professions pillars of the national economy industry, grows into the second largest industry that position in Chinese machinery industry is only second to automobile.But about 15% of the output value Reng Jinzhan world Cable industry of Chinese Cable industry, this huge market also has many development spaces and blank spot, awaits exploitation.
At extremely frigid zones such as northern China and western parts, winter temperature is low, the time is long, the temperature difference is large sooner or later, the power cable that a lot of cable factory produces there will be the phenomenon that low temperature lays sheath cracking, in recent years, numerous client proposes the technical requirements such as fire-retardant, cold-resistant, soft in the technical protocol of demand frequency-changing cable, but industry fail to provide a kind of frequency-changing cable meeting collective's performance, this adds difficulty to end product quality undoubtedly.
Utility model content
For overcoming prior art defect, the utility model object is to provide one and has cold-resistant flexible frequency-changing cable, be applicable to China northeast and the Northwest's comparatively cold district frequency conversion system cable, add the fire-retardant of cable and softness simultaneously, improve the scope of application, greatly improve the useful life of cable.
Scheme of the present utility model is as follows: a kind of cold-resistant flexible frequency-changing cable, comprises core, and described core is served as theme core and wire core, and described master core is identical with wire core structure; Core is made up of tinned conductor, conductor twining package tape, ethylene propylene diene rubber insulating barrier, aluminium-plastic tape twining package tape, tinned copper wire woven shield, EU elastic body jacket layer, cable is twisted into cable core by three master cores and three wire core, described cable core from inside to outside by cable core twining package tape, aluminium-plastic tape, tinned copper wire weave always shield layer, EU elastic body jacket layer II forms; Described master core, between wire core and cable core twining package tape, fill flame-retardant rope.
Further, described conductor adopts the 5th kind tinned copper wire is stranded and forms.
Further, described cable core twining package tape adopts glass fiber tape.
Further, described tinned copper wire woven shield, tinned copper wire braiding total screen layer textile density are not less than 90%.
Further, described filling flame-retardant rope is glass cord.
The utility model cable insulation and sheath material improve cable and resist cold, wear-resisting, decay resistance, conductor adopts the 5th kind of zinc-plated soft round copper wire lay configuration simultaneously, solve conductor resistance to oxidation and bending property, core split screen is have employed and cable core always shields in shielding, each core shielding is outer simultaneously extrudes the isolation of EU sheath, improve outside electromagnetic interference, and the electromagnetic interference can stablized due to cable generation itself between core, generally speaking compared with common frequency-changing cable, a kind of frequency-changing cable that the utility model relates to has cold-resistant, soft, corrosion-resistant, fire resistance, meet European Union RoHS environmental index.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of cold-resistant flexible frequency-changing cable, comprises core, and described core is served as theme core 12 and wire core 13, and described master core 1 is identical with wire core 2 structure; Core is made up of tinned conductor 1, conductor twining package tape 2, ethylene propylene diene rubber insulating barrier 3, aluminium-plastic tape twining package tape 4, tinned copper wire woven shield 5, EU elastic body jacket layer 6, cable is twisted into cable core by three master cores 12 and three wire core 13, and described cable core is woven always screen layer 10, EU elastic body jacket layer II 11 formed by cable core twining package tape 8, aluminium-plastic tape 9, tinned copper wire from inside to outside; Described master core 12, between wire core 13 and cable core twining package tape 8, fill flame-retardant rope 7.
Tinned conductor adopts the 5th kind tinned copper wire is stranded and forms; Cable core twining package tape adopts glass fiber tape; Tinned copper wire woven shield, tinned copper wire braiding total screen layer textile density is not less than 90%; Filling flame-retardant rope is glass cord.
Although give detailed description and explanation to embodiment of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned execution mode and change and amendment; its function produced do not exceed that specification contains yet spiritual time, all should within protection range of the present utility model.
