Referring to fig. 1, the embodiment of the present application discloses a one-time stranded electric wire, which includes a conductor layer 1, an insulation layer 2 and a protective layer 3 in sequence from inside to outside.

Referring to fig. 1 and 2, conductor layer 1 is formed by the transposition of many copper wires, is equipped with a plurality of bundles of spares in the conductor layer 1, and a plurality of bundles of spares set up along the even interval of the length direction of conductor layer 1. The binding member is a binding tape 4, the binding tape 4 is an insulating tape, and the binding tape 4 is spirally wound in the conductor layer 1. The plurality of tightening bands 4 are uniformly arranged along the length direction of the conductor layer 1, and a gap is left between adjacent tightening bands 4. One end of the tightening band 4 is disposed near the center of the conductor layer 1, and the other end extends to the outside of the conductor layer 1. The binding belt 4 binds the copper wires from inside to outside, so that the copper wires are not easy to scatter, and the normal work of the conductor layer 1 is maintained.

Referring to fig. 1, the insulating layer 2 is formed by winding a mica tape, and the insulating layer 2 is wound and coated outside the conductor layer 1.

A rubber layer 5 is arranged between the insulating layer 2 and the protective layer 3, and the rubber layer 5 is coated on the outer side of the insulating layer 2. One end of the tightening strap 4 extending beyond the conductor layer 1 is fixed to the inside of the rubber layer 5. The rubber layer 5 and the insulating layer 2 both have an insulating effect. Because one end of the binding belt 4 is fixed with the rubber layer 5, the binding belt 4 is not easy to loosen, and the copper wires of the conductor layer 1 are not easy to scatter under the cladding of the insulating layer 2. The integrity of the conductor layer 1 is therefore better.
