Optionally, a wrapping layer is arranged in the inner cavity of the inner sheath, and the wires are all positioned in the inner cavity of the wrapping layer.

Through adopting above-mentioned technical scheme, adopt the non-woven fabrics around the covering, set up around the covering makes the cable be cylindricly, prevents to loosen, and plays thermal-insulated, anticorrosive and anti-aging's effect, plays the effect of protecting the inner sheath layer.

Optionally, a braid is fixed on the outer wall of the inner sheath, and the braid is located between the inner sheath and the outer sheath.

Through adopting above-mentioned technical scheme, the weaving layer adopts the aramid fiber material to make, because aramid fiber has excellent tensile breaking resistance, aramid fiber weaving layer not only can guarantee the rounding closely of electric wire and cable, further promotes electric wire and cable's bending resistance and mechanical strength moreover, can prolong the life of cable.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the arrangement of the reinforcing rope enhances the traction strength of the cable and reduces the possibility of damage to the cable by staff in the process of towing one end of the cable; the outer sheath is arranged as a protective layer made of polyether TPU material, so that the cable has good electrolyte resistance, and damage to the cable in the electrolyte environment is reduced.

2. The arrangement of the reinforcing rope enhances the traction strength of the cable and plays a role in protecting the cable; the setting of weaving layer promotes the bending resistance performance and the mechanical strength of electric wire and cable, can prolong the life of cable to make the intensity of cable stronger, reduce the possibility of the damage that external effort caused to the cable.
