Five-core composite fireproof flat cable

Abstract

The invention discloses a five-core composite fireproof flat cable. The cable has a flat structure. Three insulation wire cores arranged in parallel and in a straight manner are arranged in the centerof the cable. Half circle of a plurality of ground wire core conductors and half circle of a plurality of neural wire cores are arranged outside the insulation wire cores in parallel. A ceramic silicon rubber anti-flaming band wraps the ground wire core conductors and the neural wire cores in a coiling manner. A mineral metal outer sheath wraps the ceramic silicon rubber anti-flaming band in an extruded manner. The mineral metal outer sheath is provided with groove holes filled with heat absorbing cotton. The cable provided by the invention has characteristics of being capable of moving, bending, putting into vertical use repeatedly, being compact in structure, small in outer diameter, easy to process, convenient for construction and the like.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a five-core composite fireproof flat cable. Background technique [0002] The five-core cable in the prior art is usually constructed by twisting five circular cores extruded with insulation, or twisting four fan-shaped cores and one circular core. The five-core cable core includes five fifth-grade cores with the same conductor cross-section, three "three big and two small" cores with large conductor cross-sections and two small conductor cross-sections, or "four big four" with large conductor cross-sections and one small conductor cross-section. A small" core. The twisting of five circular cores, especially the twisting of five circular cores with different cross-sections, has a large gap between the cores, which not only makes the roundness of the cable poor, but also tends to loosen during extrusion and construction, and the wires The core is prone to shifting. For this reaso...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there is a structure using a flat cable. Although it can be moved repeatedly, bent, or used vertically, five cores are arranged in parallel at the same time, which increases the length of the cable, and the structure is not compact; and the existing cables have poor fire resistance. The heat dissipation performance is poor, which makes the cable easy to heat and spontaneously ignite
