SU125290A1 - High Frequency Single Quad Cable with Signal Wires - Google Patents

Description

In order to carry out remote automatic control of the operation of amplifying points, spreading: Along the cable line, high-frequency long-distance cables have, in addition to the main cores, several signal cores, which are usually located between the main cores.

In this case, the signal wires in a single-quad cable do not seem to be possible to twist the main and signal wires with a different twist pitch of the two, as is done in multi-quad cables to reduce the mutual effects between the cable chains.

In the proposed one-quad cable with signal lasenn twisted relative to its geometric axis, the possibility of twisting the main and signal wires with different twisting steps is provided by placing the signal wires over or between the layers along the back of the insulation cable, or .

FIG. Figure 1 shows the placement of the signal wires in a single-quarter cable between the layers of the insulation of the cable; in fig. 2 is the same in the thickness of its protective plastic shell.

FIG. 1 and 2, the following notation is used; 1 - main conductor, 2 -signal conductor, 3 - insulating cable insulation, 4 - metal sheath, 5 - plastic sheath, 6 - screen.

Subject invention

High-frequency single-quad cable with signal wires twisted about the geometrical axis of the cable, about aphid t. No. 125290-2 -

Due to the fact that, in order to reduce mutual influences, on cable chains, the pitch of the signal cores differs from that of the core four cores, and the signal cores are located either above or between the layers of the cable insulation, or shell.
