Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

1 it is tinned copper wire conductor in figure, 2 be ethylene-propylene rubber insulated layer, 3 be polyester film isolation strip, 4 be band, 5 is chlorine Sulphur polyethylene rubber inner sheath, 6 be tinned copper wire shielded layer, 7 be chlorine sulphur polyethylene rubber oversheath.

Specific embodiment

The utility model includes cable core, and the cable core includes tinned copper wire conductor 1, is arranged outside the tinned copper wire conductor 1 Ethylene-propylene rubber insulated layer 2, the ethylene-propylene rubber insulated layer 2 form the cable core in setting polyester film isolation strip 3 outside；

Chlorine sulphur polyethylene rubber inner sheath 5, the poly- second of chlorine sulphur is arranged in the outer winding band 4 of several cable cores, the band 4 outside Tinned copper wire shielded layer 6 is set outside alkene rubber inner sheath 5, chlorine sulphur polyethylene rubber oversheath 7 is set outside the shielded layer 6.

The tinned copper wire conductor 1 is twisted by the soft filament of multiply.

Through adhesive bond on the band 4, each cable core of outer ring does not generate mutually to be connect each cable core of outer ring Touching.

The tinned copper wire shielded layer 6 is arranged circumferentially several through-holes being uniformly arranged, the wavy curved hole of through-hole Setting.

The utility model has selected high-quality tinned wird material, and for copper content up to 99.99%, conductivity is high, can effectively improve and lead The transmission performance of wire core.Conductor tin coating it is uniform securely, it is ensured that corrosion-resistant, the oxidation resistance of conductor, conductor are adopted It is twisted with the soft filament of multiply, meets cable bend requirement.Ensure cable using when be frequently bended and move.

The utility model selects the ethyl-propylene insulating materials (tg δ 0.002) of high electrical performance low dielectric loss, to improve cable Insulation performance, it is ensured that for insulating resistance of cable up to 2000 M Ω .km or more, the mutual capacitance between core is no more than 110PF/m, Mutual capacitance is no more than 140PF/m when core and shielding.In order to make insulated wire cores be more convenient for being bent and slide, guarantee insulated wire cores Electric property and be not easily susceptible to damage in moving process, prolong its service life, we are before core stranding, to every eradication Edge core outer layer uses the protected mode of heat-resistant polyester Transposed wind, increases new protective layer to insulated wire cores again more, both It is easy to remove and extend service life.

Sheath material is the guarantee of the key performances such as heat-resisting product, oil resistant, corrosion-resistant, sea water resistance, salt spray resistance, resist bending, We have selected not only softness, resist bending, good mechanical property, but also have good flame retardant property, oil resistant and sea water resistance, mould proof Bacterium, salt spray resistance chlorosulfonated polyethylene rubber sheath material, such material is my company's independent research, and performance indicator is by surveying Examination is qualified.

In order to increase cable machinery performance, increase cable flexibility, using 3+8 arranged twisted for 11 core cable conductors is tied Structure, outer layer uses 7-9 times of laying up pitch when being twisted, and internal layer uses 8-10 times of twisting pitch, guarantees that surveying magnetoelectricity cable is being bent In use process, conductor open circuit, short circuit, it is ensured that the distortion that not will cause core when cable bend, folding and unfolding reaches do not occur for cable core The accuracy for improving service life and measuring.

Oversheath selects chlorosulfonated polyethylene material to extrude using squash type, so that sheath extrudes closely knit, guarantee cable Core is not likely to produce dislocation in mobile sliding, improves cable in the service life for dragging, drawing, press use state.

The flexibility and resist bending ability of cable depend primarily on the structure of cable, and the conductor wire core in the construction of cable Structure plays a crucial role again.In order to make conductor wire core softness, resist bending, conductivity with higher, we will be led Body is designed to thin monofilament, and by the way of regular bundle strand.

It is more demanding to the thickness of cable insulation, concentricity and apparent mass etc. due to surveying magnetoelectricity cable, using moisture balance Even sulphur extrusion technique, disposably completes insulating exruded and vulcanizes, it is ensured that cable insulation compactness and concentricity ensure that electricity Insulating layer bulge phenomenon is not generated when cable is insulating exruded under up to 180 DEG C of steam ambient, while also ensuring that core is good Concentricity, uniform external diameter, the smooth rounding in surface improves insulating performance of cable and pliability.

Shielded layer uses tinned copper wire, and using numerical control tensioner and strand, braid angle is controlled 45⁰- 50⁰, braiding Coverage rate is controlled 88% or more, it is ensured that lay of braiding is uniform, surfacing, improves the shielding rejection coefficient of cable, outer to obstruct Interference when boundary's electromagnetic signal is to measurement, reduces the error generated when measurement.

It surveys magnetoelectricity cable control core conductor and uses the 5th class soft copper conductor of GB/T3956-2008, in the item that cross-sectional area of conductor is constant Under part, using tinned copper wire, the line diameter of control conductor conductor is reduced, increases single line radical, and select during bundle strand With suitable lay ratio, so as to increase flexibility, the intensity of cable core conductor.

It surveys magnetoelectricity cable in use, because of the effect for being frequently bended and stretching, core can be made to move back and forth, control line The core the big by resistance in this moving process more easily leads to its core and breaks core, drags, draws for control conductor is in use Phenomenon causes core to be broken, our wrapped one layer of high temperature resistance polyester band before single control conductor stranding, increases control conductor Relative sliding.Control conductor is set centainly to be buffered in stress, to increase the service life of control conductor.

Survey magnetoelectricity cable require can repeatedly retractable volume around, it is dilatory, and certain pulling force and spreading can be born, thus should have compared with High tensile strength and elongation and excellent corrosion resistance, and it is more more soft better.

Sheath material uses the chlorine sulphur with excellent tensile strength, wear-resisting property, flame retardant property, oil resistivity and anti-seawater Change polyethylene rubber sheath.Squash type technique is used in technique, and the tensile strength of sheath, salt spray resistance seawater, resistance to can be improved The resistance to environmental adaptability such as performance and resistance to mold corrosion is ground, is allowed to more adapt at sea use.
