By " people " character skeleton that first blade, second blade and the 3rd blade are formed, this " people " character skeleton forms first, second and the 3rd cavity by said first blade, second blade and the 3rd blade;

Said first strand is positioned at said first cavity to line, and said second strand is positioned at said second cavity to line, and said the 3rd strand is positioned at said the 3rd cavity to line;

The polyester belt coats said first strand line, second strand is twisted line and " people " character skeleton line, the 3rd;

One single face aluminium foil layer coats said polyester belt;

Flame-retardant layer coats said single face aluminium foil layer;

Drain wire is between said polyester belt and single face aluminium foil layer, and this drain wire single face aluminium foil layer therewith conducts connection.

Related content in the technique scheme is explained as follows:

1, in the such scheme, the circle diameter of said " people " character skeleton is Φ 7.0 ± 0.05mm; Said first blade, second blade and three-vaned thickness are 0.7 ± 0.05mm.

2. in the such scheme, said three pair twists are respectively string pitch: 14.7mm, 18.7mm, 11.7mm.

Because the technique scheme utilization, the utility model compared with prior art has advantage:

The utility model surpasses six types of constructions of cable and has improved input impedance and the crosstalk attenuation that surpasses six types of digital cables; And the increase pitch, thereby reduced the raw material input cost.
