Abstract

The invention discloses a four-core compound cable with control line core pairs. The four-core compound cable with the control line core pairs comprises a cable core, wherein the cable core is formed by intertwisting three fan-shaped phase line cores in the center and a wrapping belt layer wrapping the phase line cores, a cable core layer wraps the cable core, an outer sheath is arranged outside the cable core in an extrusion mode, and the cable core layer is composed of a plurality of ground wire cores and at least one control line core pair which are concentrically distributed outside the cable core side by side. The four-core compound cable with the control line core pairs is small in signal interference, can simultaneously transmit electricity and control signals, enables wires to be arranged more reasonably and more compactly, and is compact in structure, small in outer diameter, easy to process and convenient to construct.

Description

[0001] technical field

[0002] The invention belongs to the field of electric wires and cables, in particular to a four-core composite cable with control core pairs. Background technique

[0003] With the popularization of computer technology and the rapid development of the information industry, the intelligentization of residential quarters has become the development trend of modern buildings. , Under certain conditions, it is included in the integrated wiring system, and it is connected to form a complete and complete whole to meet the requirements of a high degree of intelligence.

[0004] The four-core composite cable with control cores in the prior art usually has a structure in which the control core is twisted with four extruded circular cores, or four fan-shaped cores are twisted and then twisted with the control core. combine. The four-core cable core includes four fourth-class cores with the same conductor cross-section or three 3+1 cores with a large conductor...
