Abstract

The invention discloses a flat four-core composite mineral fire-proof control cable comprising an insulated cable core and a control cable core that are arranged in parallel. Three insulating wire cores are arranged in parallel at the center of the insulated cable core; a plurality of ground wire core conductors are distributed in parallel at the peripheries of the three insulating wire cores; andthe outsides of the ground wire core conductors and the three insulating wire cores are extruded by an inner inorganic mineral metal sheath. A plurality of control wire cores are twisted and then aninner inorganic mineral metal sheath extrudes the outsides of the plurality of control wire cores to form the control cable core. The gap between the insulated cable core and the control cable core isfilled with glass fiber filaments. The outsides of the insulated cable core and the control cable core are extruded by an outer flat inorganic mineral metal sheath. The cable having advantages of compact structure, small outer diameter, and reduced occupied space can be moved repeatedly, be bent, and be used vertically and is also easy to process and convenient to construct.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a four-core composite mineral fireproof control flat cable. Background technique [0002] 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. [0003] The four-core composite cable with control cable core in the prior art usually has the structure of twisting the control cable core with four extruded round cores with insulation, or twisting the four fan-shaped cores with the control cable 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 cross-sectio...
