Embodiment Construction

[0016] Such as figure 1 , 2 As shown, the present invention includes a circular single wire 1 in the middle of the conductor. A four-layer conductor single-wire twisted layer 2 is arranged on the outer circumference of the circular conductor single wire 1. It is made up of six, twelve, eighteen, and twenty-four single conductor wires 2-1 with ladder-shaped cross-sections twisted at a pitch of 8-22 times the outer diameter of the conductor of the stranded layer; two adjacent layers The stranding direction of the conductor stranded layer 2 is opposite; the outer surface of each conductor single wire 2-1 with a trapezoidal cross-section is provided with an insulating coating 3; the thickness of the insulating coating 3 is 0.001~0.02mm; trapezoidal conductor The single wire 2-1 and the circular conductor single wire 1 have the same carrying area.

[0017] Such as image 3 , 4 As shown, the round conductor single wire 1 and the innermost conductor single wire stranded layer 2-1 adopt ...

Abstract

The invention relates to the technical field of design of conductors, and discloses a single line separated conductor. The single line separated conductor comprises a circular conductor single line, a plurality of conductor single line twisted layers are arranged on the periphery of the circular conductor single line, each conductor single line twisted layer is formed by twisting conductor single line bodies at a pitch which is 8-22 times of the conductor outer diameter of the conductor single line twisted layer, and the outer surface of each conductor single line body is provided with an insulation coating. Due to the fact that the insulation coatings are arranged among the conductor single line bodies, the surface area of the conductor is increased, the current-carrying capacity is improved greatly, the line loss is reduced, the power transmission cost is lowered, and due to the coatings, the conductor has certain corrosion resistance.

Description

Technical field [0001] The invention relates to the technical field of conductor design. Background technique [0002] If the conductor passes AC current, due to the distributed inductance, the external inductance blocks most of the applied voltage, and large current flows only close to the surface. Due to the distributed inductance voltage drop, the surface voltage drop is the largest, from the surface to the center. Gradually decrease, the current from the surface to the center becomes smaller and smaller, and there is even no current, that is, no magnetic field. This is the skin effect or skin effect. This phenomenon exists in power cables. In order to increase the current carrying capacity of the cable, the method of increasing the conductor section is usually adopted. However, due to the existence of this skin effect, the interception capacity in the conductor does not increase proportionally with the increase of the cable conductor, but when the diameter of the conductor ...
