Abstract
The utility model relates to a five plus one split conductor of a copper core of a large cross section, comprising a stranded conductor of a central unit and five sector copper-cored strand blocks of the same size and cross section shape. The five sector copper-cored strand blocks are successively wound around a circumference of the stranded conductor of a central unit; only one of the five sector copper-cored strand blocks is directly contacted with the stranded conductor of a central unit; insulating tapes are arranged between the other four sector copper-cored strand blocks and the stranded conductor of a central unit; the insulating tapes are respectively arranged between the five sector copper-cored strand blocks; and semi-conducting Tetolon belts are wrapped around the central unit and the five sector copper-cored strand blocks. According to the conductor of a large cross section of the utility model, influence of AC skin effect is substantially reduced; an AC resistor of the conductor is reduced; transmission capacity of a cable is substantially increased; the conductor is more firm; and processing is not easy to loose.
Description
Technical field
The utility model relates to a kind of cable conductor, relates in particular to a kind of heavy in section copper core 5+1 milliken conductor.
Background technology
The kelvin effect of the conductor that the heavy in section circle is pressed and approach effect have increased the AC resistance of conductor; Loss ratio to electric power is bigger, same cross section conductor, and its ampacity is lower; Therefore in high-tension cable is produced; 800mm2 and above needs adopt the conductor of segmenting structure, are used to solve the interchange kelvin effect of big carrying surface conductor, reduce the AC resistance of conductor.
The utility model content
Kelvin effect, the reduction conductor AC resistance influence of the utility model in order to reduce conductor, heavy in section copper core conductor adopts the 5+1 structure.
The technical scheme of the utility model is: comprise the fan-shaped copper core thigh piece that a center cell stranded conductor is all identical with five sizes and cross sectional shape; Described five fan-shaped copper core thigh pieces are wrapped in outside the center cell stranded conductor circumference successively; Have only a fan-shaped copper core thigh piece directly to contact among described five fan-shaped copper core thigh pieces with the center cell stranded conductor; Be provided with insulating tape between remaining four fan-shaped copper core thigh pieces and the center cell stranded conductor; Be respectively equipped with insulating tape between five fan-shaped copper core thigh pieces, described center cell and five outer wrapped special many tengential belts of partly leading of fan-shaped copper core thigh piece.
Described insulating tape is for sending out the insulating paper of wrinkle.
The large size conductor of the utility model structure reduces the influence that exchanges kelvin effect greatly, reduces the AC resistance of conductor, has improved the transmission capacity of cable greatly, and conductor is more firm, and processing is difficult for loose.
Description of drawings
Fig. 1 is the utility model structural representation.
1 is the center cell stranded conductor among the figure, the 2nd, and fan-shaped copper core thigh piece, the 3rd, insulating tape, the 4th, partly lead special many tengential belts.
Embodiment
Heavy in section copper core 5+1 milliken conductor comprises the fan-shaped copper core thigh piece 2 that a center cell stranded conductor 1 is all identical with five sizes and cross sectional shape, and described center cell stranded conductor 1 is 50mm
2Outside diameter control is at 8.0-8.03mm; D.C. resistance in the time of 20 ℃ is not more than 0.387 Ω/km; Described five fan-shaped copper core thigh pieces 2 are wrapped in outside center cell stranded conductor 1 circumference successively, have only a fan-shaped copper core thigh piece 2 directly to contact with center cell stranded conductor 1 among described five fan-shaped copper core thigh pieces 2, are provided with insulating tape 3 between remaining four fan-shaped copper core thigh pieces 2 and the center cell stranded conductor 1; Be provided with insulating tape 3 between five fan-shaped copper core thigh pieces 2, described center cell stranded conductor 1 and five fan-shaped copper core thigh piece 2 outer wrapped special many tengential belts 4 of partly leading.Fan-shaped copper core thigh piece 2 is pressed 25-30 times of pretwist of conductor diameter behind the stranding; Fan-shaped copper core thigh piece 2 carries out layering and presses also pretwist; Pretwist can reduce the internal stress of the utility model; Improve the structural stability of the utility model, described insulating tape 3 is for sending out insulating paper or other insulating material of wrinkle, and the THICKNESS CONTROL of insulating paper or other insulating material is at 0.15-0.2mm.
Claims (2)
1. heavy in section copper core 5+1 milliken conductor; It is characterized in that: comprise the fan-shaped copper core thigh piece that a center cell stranded conductor is all identical with five sizes and cross sectional shape; Described five fan-shaped copper core thigh pieces are wrapped in outside the center cell stranded conductor circumference successively; Have only a fan-shaped copper core thigh piece directly to contact among described five fan-shaped copper core thigh pieces with the center cell stranded conductor; Be provided with insulating tape between remaining four fan-shaped copper core thigh pieces and the center cell stranded conductor, be respectively equipped with insulating tape between five fan-shaped copper core thigh pieces, described center cell and five outer wrapped special many tengential belts of partly leading of fan-shaped copper core thigh piece.
2. heavy in section according to claim 1 copper core 5+1 milliken conductor is characterized in that: described insulating tape is for sending out the insulating paper of wrinkle.
