A kind of novel cableTechnical field
The present invention relates to field of cable technology, more particularly to a kind of novel cable.
Background technology
Cable is typically by several or the cable of similar rope that several groups of wires (every group at least two) are twisted, every groupMutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the coating of high-insulation, and cable hasInterior energization, the feature of external insulation.
Cable is widely used in electric power, communications, with the continuous development of technology, the complexity of the applicable occasion of cableChange, variation.At present, the structure of cable is generally multiple cores and is directly wrapped in insulating materials, is not deposited between adjacent coreIn spacing, done in this way, electromagnetism can occur during different signals transmits in respective core, between different signalsPhenomenon is disturbed, have impact on the application of the cable, while does not also possess corresponding heat-resisting ability and anti-wear performance, and cable is anti-Press tensile capacity poor.
The content of the invention
The present invention is in order to overcome deficiency of the prior art, there is provided a kind of novel cable.
The present invention is to be achieved through the following technical solutions：
A kind of novel cable, including some cable cores wound by copper wire, in the appearance bread of every cable coreInner protective layer is covered with, high-temperature-resistant layer is coated with the outer surface of the inner protective layer, is coated in the outer surface of the high-temperature-resistant layerThere is dacron thread braiding layer, PP rope packed layers are coated with the outer surface of the dacron thread braiding layer, in PP rope packed layersOuter surface is coated with polyolefin layer；Foaming block is filled between the gap of every cable core；In the outer of multi-cable core bodyPortion is provided with antistatic layer, and screen layer is coated with the outer surface of the antistatic layer, is coated in the outer surface of the screen layerThere is wearing layer, external protection is coated with the outer surface of the wearing layer.
As the preferred technical solution of the present invention, the quantity of the cable core is three.
As the preferred technical solution of the present invention, the screen layer is identical with the thickness of wearing layer.
As the preferred technical solution of the present invention, the thickness of the antistatic layer is 1mm-2mm.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is by being provided with inner protective layer and outer protectionLayer, it is possible to increase the protective value of cable；By being provided with high-temperature-resistant layer, it is possible to increase the resistance to elevated temperatures of cable；By settingIt is equipped with dacron thread braiding layer, PP ropes packed layer, polyolefin layer, it is possible to increase its resistance to compression tensile property, extend the use of cableLife-span；By being provided with foaming block, the protective value of cable is improved；By being provided with antistatic layer, it is possible to increase it is anti-quietThe ability of electricity；It is strong by being provided with screen layer interference rejection ability；By being provided with wearing layer, it is possible to increase the wearability of cableEnergy.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and ExamplesThe present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, andIt is not used in the restriction present invention.
Referring to Fig. 1, a kind of described novel cable, including some cable cores 1 wound by copper wire, in every electricityThe outer surface of cable core body 1 is coated with inner protective layer 2, high-temperature-resistant layer 3 is coated with the outer surface of the inner protective layer 2, describedThe outer surface of high-temperature-resistant layer 3 is coated with dacron thread braiding layer 4, and PP ropes are coated with the outer surface of the dacron thread braiding layer 4 and are filled outLayer 5 is filled, polyolefin layer 6 is coated with the outer surface of PP rope packed layers 5；Filled between the gap of every cable core 1There is foaming block 7；The outside of multi-cable core body 1 is provided with antistatic layer 8, is coated with the outer surface of the antistatic layer 8Screen layer 9, wearing layer 10 is coated with the outer surface of the screen layer 9, and outer guarantor is coated with the outer surface of the wearing layer 10Sheath 11.
The screen layer 9 is identical with the thickness of wearing layer 10, and the thickness of the antistatic layer 8 is 1mm-2mm.
When in use, by being provided with inner protective layer 2 and external protection 11, it is possible to increase the protective value of cable；Pass throughIt is provided with high-temperature-resistant layer 3, it is possible to increase the resistance to elevated temperatures of cable；By be provided with dacron thread braiding layer 4, PP restrict packed layer 5,Polyolefin layer 6, it is possible to increase its resistance to compression tensile property, extend the service life of cable；By being provided with foaming block 7, improveThe protective value of cable；By being provided with antistatic layer 8, it is possible to increase its anlistatig ability；By being provided with screen layer 9So that interference rejection ability is strong；By being provided with wearing layer 10, it is possible to increase the anti-wear performance of cable.
Above are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit andAll any modification, equivalent and improvement made within principle etc., should be included in the scope of the protection.
