Description

{THE CABLE STRANDING APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable twisted pair cable, and more particularly, to a cable twisted pair cable in which a single stranded cable is twisted in a plurality of strands like a stranded wire to produce a cable such as electric wire, power wire, insulated wire, To a cable twisted pair.

Messenger wire installed on the catenary line is a wire that stands on the top of the curtain curve and keeps it horizontal at the same height while bundling it with a hanger or dropper line.

The wire bundle and the electric wire are supported by a movable bracket provided at regular intervals, the wire bundle being supported by supporting brackets supported by the movable bracket, The curtain line curved downward is maintained by the curved line, and the catenary line is kept horizontal by the dropper line installed at regular intervals.

These joint lines or dropper lines are used as national infrastructure, and Korea Railway Authority has specified separate specification or standard.

Specifically, the dropper wire for the wire line or the machining line used in the catenary wire is formed by the copper alloy magnesium (CuMg) wire. The standard chemical composition of the wire is classified according to the IACS (International Interlocking Standard) conductivity, and the IACS conductivity is 72% The contents should satisfy 0.3% ~ 0.4%, tin content N / A and other impurities maximum 0.03%.

In addition, the construction related to the twisted pair should satisfy the specifications shown in the table below. Specifically, the twist rate of each side should be within the limit given in the table according to the number of twisted wires (n) of the related layer. In cables with multiple strands of stranded wire, the elongation of any particular layer shall not exceed the elongation of the immediately underlying layer, and the difference should not be more than 0.5.

The term "elongation rate" as used herein refers to the ratio between the spiral diameters formed by one of the layers and the cable components, and in some cases the inner diameter, average diameter or outer diameter of the layer comprising the elements arranged in the spiral must be taken into account, It is customary.

When the cable is set up vertically, the twisted wire can be loosened along the central part of the alphabet Z or S, and the joining direction of the electron (Z) is called the right hand direction and the latter (S) is called the left hand direction.

Meanwhile, in order to manufacture the above-described wire or dropper wire, a drawn single-stranded cable is subjected to a stranding process of twisting a plurality of strands like a rope.

Referring to FIG. 1, a conventional cable twisting apparatus is shown. A spool is disposed in a known manner on a rotor 1, and a cable 2 is wound on the spool.

When the cable 2 is twisted, the cable 2 is continuously released from the spool, and the rotor 1 is rotated in one direction. The unwound cable 2 is guided by the yarn splicing point 3 and at the yarn splicing point 3 the cable 2 is stranded with one cable in a known manner.

The twisted cable is pulled from the twist point 3 by a roller or the like and wound on a separate cable drum.

However, such a general cable stranding method is generally used for manufacturing a copper wire having high ductility. For a steel having high ductility, a cable made of an alloy of magnesium and magnesium for improving the stiffness and strength has high stability, And there is a phenomenon that it is released again after passing.

Therefore, it is difficult to manufacture a wire or a dropper wire of CuMg material by the conventional cable stranding method.
