Abstract
The utility model discloses a soft copper stranded wire. The soft copper stranded wire comprises a plurality of soft braided wires which are stranded with each other, wherein each soft braided wire comprises a plurality of soft round copper wires which are arranged in a bundle shape; a plurality of soft round copper wires in each soft braided wire are stranded with each other or are arranged in parallel; each soft round copper wire has a diameter A of 0.45 mm; the soft copper stranded wire comprises at least seven soft braided wires; and each soft braided wire comprises at least seven soft round copper wires. The soft copper stranded wire has the advantages of high softness and assembly performance.
Description
Technical field
The utility model relates to field of cables, is specifically related to a kind of soft copper stranded conductor that is used for electric equipments such as transformer.
Background technology
The copper stranded conductor that electric equipments such as the transformer of prior art are used all is to adopt structure to meet the copper stranded conductor of GB GB3953, and this GB GB3953 copper stranded conductor that meets is by many stranded formation of soft strand, and the soft strand of each root is by many stranded formation of soft attitude circular copper wire.But because the soft strand of each root is by many stranded formation of soft attitude circular copper wire; This is less and stranded technology causes the pitch diameter of soft strand; Therefore the soft strand of this copper stranded conductor is harder relatively; This is bigger for the soft attitude circular copper wire diameter of the soft strand of this copper stranded conductor in addition, makes whole copper stranded conductor harder relatively, influences the assembly performance of electric equipments such as transformer.
The utility model content
The technical problem that the utility model will solve provides the soft copper stranded conductor that a kind of pliability is high, assembly performance is good.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of soft copper stranded conductor comprises many mutual stranded soft strands, and said soft strand comprises many soft attitude circular copper wires that are the pencil layout.
Further improvement as technique scheme:
Stranded each other or be arranged in parallel between the many soft attitude circular copper wires in the said soft strand.
The diameter A of said soft attitude circular copper wire is 0.45mm.
Said soft copper stranded conductor comprises at least 7 soft strands; Said soft strand comprises at least 7 soft attitude circular copper wires.
The utlity model has following advantage: the soft strand of the utility model comprises many soft attitude circular copper wires that are the pencil layout; The radical of soft attitude circular copper wire does not receive the restriction of regular stranded rule in the soft strand; Therefore design load more can be approached in the cross section of soft strand; Improve the pliability of copper stranded conductor greatly, thereby significantly improved the assembly performance of electric equipments such as transformer, had pliability height, advantage that assembly performance is good.

Fig. 2 is the sectional structure sketch map of the soft strand of the utility model embodiment.
Marginal data: 1, soft strand; 2, soft attitude circular copper wire.
Embodiment
As depicted in figs. 1 and 2, the soft copper stranded conductor of present embodiment comprises many mutual stranded soft strands 1, and soft strand 1 comprises many soft attitude circular copper wires 2 that are the pencil layout.Soft strand 1 is processed by many soft attitude circular copper wire 2 transmitted beam system processes; The radical of soft attitude circular copper wire 2 does not receive the restriction of regular stranded rule in the soft strand 1; Therefore design load more can be approached in the cross section of soft strand 1; Improve the pliability of copper stranded conductor greatly, thereby significantly improved the assembly performance of electric equipments such as transformer.In the present embodiment; Soft copper stranded conductor comprises 7 soft strands 1; Soft strand 1 comprises 7 soft attitude circular copper wires 2, and soft in addition copper stranded conductor also can adopt the soft strand 1 of greater number as required, and soft strand 1 also can adopt the soft attitude circular copper wire 2 of greater number as required; Quantity flexibility more at most is good more, but processing is relatively more difficult.
Stranded each other or be arranged in parallel between the many soft attitude circular copper wires 2 in the soft strand 1.In the present embodiment, be arranged in parallel between the many soft attitude circular copper wires 2 in the soft strand 1, thereby the cross section of guaranteeing soft strand 1 can be approached design load more.
In the present embodiment, the diameter A of soft attitude circular copper wire 2 is 0.45mm, and the diameter of the soft attitude circular copper wire 2 in the copper stranded conductor of the relative GB GB3953 of this diameter is little, therefore makes that the flexibility of soft attitude circular copper wire 2 is better relatively.
The above is merely the preferred implementation of the utility model, and the protection range of the utility model is not limited in above-mentioned execution mode, and every technical scheme that belongs to the utility model principle all belongs to the protection range of the utility model.For a person skilled in the art, some improvement and the retouching under the prerequisite of the principle that does not break away from the utility model, carried out, these improvement and retouching also should be regarded as the protection range of the utility model.
