Preferably, the inner shielding layer and the outer shielding layer are both tinned copper wire braided shielding layers. The double-layer shielding layer structure enables the cable to obtain a better shielding effect, and has a double-layer shielding effect of sub-shielding and total shielding, so that efficient and stable transmission of signals is ensured.

Preferably, the insulating layer is a silicon rubber insulating layer.

Preferably, the inner sheath is a polyethylene inner sheath; the outer sheath is a polyvinyl chloride sheath.

Preferably, the cross section of the framework unit is strip-shaped, and the two tensile core wires are positioned at two ends of the cross section of the framework unit.

Preferably, the tensile core wire is an aramid fiber tensile core wire. Two tensile heart yearns that distribute from top to bottom provide more tensile properties for the cable, and the design of two tensile heart yearns makes radially different positions can both obtain fine tensile effect.

Preferably, the backbone unit is a fluororubber backbone unit. The skeleton unit is the main part that radial pressure was born to the cable, through setting up elastic fluorine rubber skeleton unit, can make the cable obtain more radial pressure buffering to guarantee the life of cable.

Has the advantages that: the utility model provides a cable unit is shown in the figure, adopts a skeleton unit of two cable unit combination collocation to utilize interior sheath, outer shielding layer and oversheath to carry out the mode of cladding, thereby because the design of elasticity skeleton unit (still the cladding has two tensile heart yearns that distribute from top to bottom in the elasticity skeleton unit), thereby no matter in length direction or the footpath of cable, all make the cable have better tensile, withstand voltage effect. And this application of cable adopts total shielding and divides shielded double-deck shielding effect to the shielding effect of totality is good, ensures the high-efficient stable transmission of signal.
