SU20713A1 - Flexible electrical wire - Google Patents

Description

The present invention relates to a flexible electrical wire device and is intended to increase the filling ratio of its cross section.

In FIG. 1-6 depict the cross-section of the proposed wire of various shapes; FIG. 7-section of a separate wire strand.

Each wire strand (Fig. 7) consists of a central wire 1 and the seven or more wires 2 surrounding it of smaller diameter than the central wire. The straps are twisted, and additional wires 3 are added to them (Fig. 1). X Outer strands may be located around a central one or several rows, as shown in FIG. 1, 4 and 5.

It is possible to take for each strand all wires of the same diameter (Fig. 2 and 3). In this case, the central strand is twisted from thicker wires than all the others, and single wires 3 can also be laid between the strands (Fig. 3). For large wires, it is more convenient to arrange the wires as shown in FIG. 6. Here, simple straps 4 form together with wires 3 laid between them complex strands 5, which are twisted into a wire, and separate simple ones are laid between BAT

strand 4, in exactly the same way as single wires were laid inside the complex strand 3.

The subject of the patent.

1. A flexible electrical wire, consisting of several strands twisted together, characterized in that each strand is both central and external, consists of one central wire and seven or more wires surrounding it with a smaller diameter, with additional single wires can be laid between strands.

2. The variation of the wire described in paragraph 1, characterized in that the diameter of the wires of the central strand is larger than the diameter of the wires surrounding it, and the wires belonging to any single strand, both central and outer, have the same diameter .

3. Change as described in p. 1 and 2 wires, characterized in that when using dL twisting the wires of a complex cable, each complex cable consists of a number of simple cables with additional single wires between them, and additional simple cables are laid between the complex cables.
