Shielded layer 22 and insulating layer 23 form, and multiply conductor wire core 21 is formed as multilayered structure, during wherein one conductor wire core 21 is located at
The heart, remaining multiply are arranged in multilayer from inside to outside in a ring and radially around the center, the conductor wire core 21 of adjacent layer
Stranding is contrary, to further improve 20 torsional resistance of conductive cable core in the way of stranding.
In order to reduce the electromagnetic effect generated after energization between conductor wire core 21, wrapped conductor wire core outside conductor wire core 21
Shielded layer 22, and in order to avoid generating short circuit between conductor wire core 21, in 22 outsourcing insulating layer coating 23 of conductor wire core shielded layer.
As Fig. 1 totally 19 strands of conductor wire core 21, forms three one-tenth arrangements from inside to outside, wherein 1 burst of position in some instances
In the center of conductor wire core 21,6 strands around centrally located 1 strand of conductor wire core 21, spiral forms time outer layer to the right, and another
Outer 12 strands can make conductive cable core 20 be formed preferably around time outer layer spiral winding to the left in this way by positive and negative continuous winding
Flexibility, and then improve torsional resistance, prolong the service life.
Further, such as Fig. 1, shock absorber part is formed as rubber strip, and shock absorption strip 10 has two, conductive cable core 20 totally three,
Root, three conductive cable cores, 20, two rubber strips and a whole twisted synthesizing cable of ground cable core 30, wherein always twist laying up pitch
It is 6-8 times of laying up diameter, for example, always twisting laying up pitch is 6 times, 7 times or 8 times of laying up diameter, in this way, both can be to avoid
Total distortion performance for twisting the too small fluorescence trailing cable 100 of laying up pitch is poor, can also be excessive then glimmering to avoid total strand laying up pitch
The bending property of light trailing cable 100 is poor, and then guarantees the whole torsional resistance of fluorescence trailing cable 100 and counter-bending
Performance.
The cable making method of embodiment according to a second aspect of the present invention is described with reference to the accompanying drawing.
Cable preparation method according to an embodiment of the present invention, comprising the following steps:
First, conductive cable core is prepared, center uses one conductor wire core, and secondary outer layer uses 6 bursts of conductor wire core dextrad spirals
It is set around centrally located peripheral side, third layer is set around on the outside of time outer layer using 12 strands of conductive cable core sinistral coilings, wherein phase
The contrary arrangement of the stranding of the conductor wire core of adjacent bed, wherein successively using overlapping around packet mode on the outside of multiply conductor wire core
It arranges conductor wire core insulating layer and shielded layer, Duplication 45%-55%, obtains conductive cable core, and can by setting Duplication
To guarantee insulation and shield effectiveness, drain conditions are avoided the occurrence of.
Second, the first damping, buffering is placed in the middle part of more conductive cable cores, and make more conductive cable cores one a pair of
It is attached at multiple first curved mounting surfaces with answering, every conductive cable core is tangent with conductive cable core adjacent thereto, subtracts multiple
Shake part and ground cable core be set between the adjacent conductive cable core of any two correspondingly, by conductive cable core, shock absorber part and
Ground cable core entirety twisted synthesizing cable, total strand laying up pitch is 6-8 times of laying up diameter, for example, always twisting laying up pitch is outside stranding
6 times, 7 times or 8 times of diameter, in this way, both can be poor to avoid total distortion performance for twisting the too small cable of laying up pitch, it can also keep away
The bending property for exempting from always to twist the excessive then cable of laying up pitch is poor, and then guarantees the torsional resistance of cable entirety and counter-bending
Performance;
Third, in more conductive cable cores, the waterstop of the wrapped double-sided insulation of periphery wall of multiple shock absorber parts and ground cable core;
4th, inner sheath, woven mesh layer are set gradually except waterstop, is vulcanized using steam, and neighbouring block water is made
Inner sheath insertion conductive cable core with side and the gap between ground cable core, and make the tighter gap of inner sheath and woven mesh layer
The preparation of inner sheath, woven mesh layer is completed in adhesion, and high-strength rubber inner sheath can be made to be completely embedded by steam vulcanization (cure)
Space hold is reduced so that overall structure is more compact in the gap that the periphery wall of conductive cable core and ground cable core is formed, and
And also may be implemented to buffer three times using high-strength rubber inner sheath (i.e. high-intensitive inner sheath buffering, the first damping, buffering layer and
