Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the following embodiments.

The utility model discloses a first embodiment provides a rectangle transposition circle aluminium wire, see fig. 2, and it includes conductor 1 that two winding displacement transposition formed and is located the outside insulator 2 of conductor, and this insulator 2 adopts insulating film, the insulating film outside is provided with carbon fiber net layer 3 and sets up in the polytetrafluoroethylene material layer 4 on carbon fiber net layer 3 surface.

It is worth mentioning that the four corners of the polytetrafluoroethylene material layer 4 are provided with the reinforced steel wires 8, and the tensile property of the product can be greatly improved due to the four steel wires. The cross section of the reinforced steel wire is in a cross shape or a triangular shape, and the steel wire with the shape can be prevented from rotating and the like after being embedded into a polytetrafluoroethylene material.

The second embodiment of the present invention provides a rectangular transposed round aluminum wire, which is different from the first embodiment in that, referring to fig. 3, a shielding layer 5, for example, a shielding layer composed of tin foil, is provided between the carbon fiber mesh layer and the polytetrafluoroethylene material layer.

In addition, the outer part of the conductor can be provided with a paint film layer.

The utility model discloses the third embodiment provides a rectangle transposition circle aluminium wire, its difference with the first embodiment lies in, see figure 4, 4 outsides in polytetrafluoroethylene material layer are provided with color changing silica gel layer 6, color changing silica gel layer outside is provided with flexible stratum lucidum 7, and flexible stratum lucidum material transparent plastic is suffered under the damaged condition because of external force at this product, and water can enter into color changing silica gel layer through transparent plastic, and color change then takes place on the color changing silica gel layer this moment to the outer protection architecture of suggestion product has damaged, needs in time to change.

In addition, the steel wire can also adopt a round steel wire, the diameter of the steel wire can be 2-6mm, and the steel wire is selected and applied according to products with different sizes.

It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
