An object of the utility model is to overcome above-mentioned prior art not enough, provide an independent cable of core, this internal interior insulating tube that establishes of cable, a plurality of semicircle recesses of the outer periphery equipartition of internal insulation outside of tubes are six, a plurality of semicircle recesses of the three inside equipartitions of through-hole of outer insulating sleeve are three, the outer insulating sleeve suit is outside of tubes and the elasticity laminating of internal insulation, the semicircle recess of outer insulating sleeve is three and six butt joints of semicircle recess of internal insulation constitute a plurality of diameters and the round hole that insulating shield sleeve external diameter size accords with, it is downthehole that outer parcel insulating shield sleeve's conductor packs into the round hole, the outer oversheath layer parcel of outer peripheral hardware behind the outer insulating sleeve armor, the utility model discloses each core line mutual independence and noninterference can improve the.

In order to achieve the above purpose, the technical scheme of the utility model is that: a cable with independent wire cores comprises a cable body, wherein an inner insulating tube is arranged in the cable body, a plurality of semicircular grooves six are uniformly distributed on the outer circumferential surface of the inner insulating tube with six through holes, an insulating shielding sleeve is arranged in the six through holes, and a conductor is wrapped by the five inner walls of the through holes of the insulating shielding sleeve;

a plurality of semicircular grooves III are uniformly distributed in the through holes III of the outer insulating sleeve, the arc radius of the semicircular grooves III is the same as that of the semicircular grooves VI, and the position angles of the semicircular grooves III correspond to those of the semicircular grooves VI;

the outer insulating sleeve is sleeved outside the inner insulating pipe, the inner walls of the three through holes of the outer insulating sleeve are elastically attached to the outer circumferential wall of the inner insulating pipe, the third semicircular groove of the outer insulating sleeve is in butt joint with the sixth semicircular groove of the inner insulating pipe to form a plurality of circular holes with the diameter consistent with the outer diameter of the insulating shielding sleeve, and the conductor wrapped by the insulating shielding sleeve is arranged in the circular hole formed by the butt joint of the third semicircular groove and the sixth semicircular groove;

the outer insulating sleeve is externally provided with an armor, a second through hole is formed in the outer protective sleeve layer, and the armor is wrapped by the inner wall of the second through hole.

Further, the outer insulating sleeve and the inner insulating pipe are both made of high-density polyethylene HDPE materials.

The utility model has the advantages that: the utility model discloses each heart yearn mutual independence and noninterference can improve the safety and stability nature of use greatly, strengthens anti-interference effect.
