The first embodiment is as follows:

as shown in fig. 1 and 2, the abrasion-resistant electric wire comprises a wire core 1, a PVC insulation protection layer 2 wrapping the outside of the wire core 1, a first spiral abrasion-resistant layer 3, an embedding hole 5 and a ball 6; the first spiral wear-resistant layer 3 is arranged outside the PVC insulation protective layer 2 in a surrounding mode, the surface of the first spiral wear-resistant layer 3 is provided with a plurality of embedding holes 5, and the balls 6 are movably embedded into the embedding holes 5.

In this embodiment, the ball 6 has a volume greater than 1/2 of the volume of the insertion hole 5. The balls 6 are metal balls. When a constructor lays a wire and pulls the wire, the ball 6 contacts the ground, so that the surface of the wire is separated from the ground by a certain distance to play a role of abrasion resistance; and through 6 pulling electric wires of balls, the frictional force between the electric wires and the ground can be greatly reduced, so that constructors can pull the electric wires at a higher speed, the pulling time of the electric wires can be shortened under the condition of the same length and the stretching distance, the labor is saved, and the pulling force born by the electric wires is also reduced.

In this embodiment, a second spiral wear-resistant layer 4 is arranged around the outside of the PVC insulating protective layer 2, and the first spiral wear-resistant layer 3 and the second spiral wear-resistant layer 4 have the same structure and size. First spiral wearing layer 3 and second spiral wearing layer 4 all bulge in the surface of PVC insulation protection layer 2, just the spiral direction of first spiral wearing layer 3 and second spiral wearing layer 4 is opposite. The first spiral wear-resistant layer 3 and the second spiral wear-resistant layer 4 are arranged outside the PVC insulating protective layer 2, the first effect is that the wear-resistant layer of the wire is directly thickened, and the second effect is that the torsion resistance of the wire is increased to a certain extent due to the fact that the spiral directions of the first spiral wear-resistant layer 3 and the second spiral wear-resistant layer 4 are opposite.

In this embodiment, the balls 6 are movably embedded in the second spiral wear-resistant layer 4.

In this embodiment, the first spiral wear-resistant layer 3 and the second spiral wear-resistant layer 4 are made of PVC.
