Problems solved by technology

[0002] The skin effect and proximity effect of a large cross-section circular compacted conductor increase the AC resistance of the conductor, and the loss of power is relatively large. The same cross-section conductor has a relatively low carrying capacity.

Embodiment Construction

[0009] A large cross-section copper core split conductor, including a central unit stranded conductor 1 and five fan-shaped copper core strands 2 with the same size and cross-sectional shape, the central unit stranded conductor 1 is 50mm 2 , the outer diameter is controlled at 8.0-8.03mm, and the DC resistance at 20°C is not greater than 0.387Ω / km. The five fan-shaped copper core strands 2 are wound around the circumference of the central unit stranded conductor 1 in turn, and the five Among the four fan-shaped copper core strands 2, only one fan-shaped copper core strand 2 is in direct contact with the central unit stranded conductor 1, and an insulating tape is provided between the remaining four fan-shaped copper core strands 2 and the central unit stranded conductor 1 3. An insulating tape is provided between the five fan-shaped copper core strands, and the central unit stranded conductor 1 and the five fan-shaped copper core strands 2 are wrapped with a semi-conductive tef...

Abstract

The invention relates to a copper core (5+1) dividing conductor with large cross section. The copper core dividing conductor comprises a central unit stranding conductor and five sector-shaped copper core stand blocks with the same size and cross section shape, wherein the sector-shaped copper core stand blocks are sequentially wound outside the periphery of the central unit stranding conductor; only one of the sector-shaped copper core stand blocks is directly contacted with the central unit stranding conductor; insulating belts are arranged between the other sector-shaped copper core stand blocks and the central unit stranding conductor; an insulating belt is arranged between every two sector-shaped copper core stand blocks; and semiconducting Tetoron belts are wound on the central unit stranding conductor and the five sector-shaped copper core stand blocks. The influence of an alternating-current skin effect is greatly reduced by the conductor with the large cross section, the alternating-current resistance is reduced, the transmission capacity of a cable is greatly improved, and the conductor is firmer and is not easy to loosen during processing.

Description

technical field [0001] The invention relates to a cable conductor, in particular to a copper core split conductor with a large section. Background technique [0002] The skin effect and proximity effect of a large cross-section circular compacted conductor increase the AC resistance of the conductor, and the loss of power is relatively large. The same cross-section conductor has a relatively low carrying capacity. Contents of the invention [0003] In order to reduce the skin effect of the conductor and reduce the influence of the AC resistance of the conductor, the present invention adopts a 5+1 structure for the large-section copper core conductor. [0004] The technical solution of the present invention is to include a central unit stranded conductor and five fan-shaped copper core strands with the same size and cross-sectional shape, and the five fan-shaped copper core strands are wound around the circumference of the central unit stranded conductor in turn , among th...
