Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of power cable with heat dissipation performance, including external protection 1, braiding layer 4 and external shielding layer
6, the outer wall interval of external protection 1 is uniformly provided with air hole 3, and the inside adhesion of air hole 3 has the waterproof with waterproof effect
Ventilated membrane 2, and the inside of external protection 1 is equipped with braiding layer 4, the inside of braiding layer 4 are equipped with external shielding layer 6, external shielding layer 6 it is interior
Side interval is uniformly provided with four conducting wires 7, and the outer sheath of conducting wire 7 is equipped with heat-dissipating cylinder 5, and the appearance face interval of heat-dissipating cylinder 5 is uniformly provided with
Aperture for heat dissipation.
There are four heat-dissipating cylinder 5 is arranged altogether, and four heat-dissipating cylinders 5 are respectively sleeved at the outside of four conducting wires 7, four heat-dissipating cylinders
