Abstract
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...

Embodiment Construction
[0013] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0014] Such as figure 1 As shown, a four-core composite cable with a control core pair includes a cable core, and the cable core is twisted by three fan-shaped phase cores 1 in the center and a tape layer 2 wrapped around the phase core 1. The wire core layer 3 is wrapped around the cable core, and the outer sheath 4 is extruded outside the cable core; the wire core layer 3 is composed of 10 ground wire cores 5 and 3 pairs of control wire core pairs arranged side by side and concentrically outside the cable core. 6 composition.
[0015] The phase core 1 is composed of a fan-shaped phase conductor 8 composed of several monofilaments 7 and an insulating layer 9 wrapped around the fan-shaped phase conductor 8 .
[0016] The pair of control wire cores 6 is composed of two control wire cores 10 pulled directly, a metal braided shielding layer 11 wrapped a...
