Problems solved by technology

However, in flame-retardant cables, thicker fire-resistant and smoke-suppressing layers or multi-layer flame-retardant and smoke-suppressing knot claddings are usually designed, which makes the cables very bulky and less flexible.

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] combine Figure 1-Figure 3 The fire-resistant and flame-retardant composite flexible cable of the exemplary embodiment shown includes a PVC protective inner shell 1, and the interior of the PVC protective inner shell 1 is arranged in a circular arrangement with three sets of cable conductive cores 2, and the outer wall of the PVC protective inner shell 1 is wrapped with PVC. The protective shell 3, the PVC protective shell 3 and the PVC protective inner shel...

Abstract

The invention belongs to the technical field of cables, and discloses a fireproof flame-retardant composite flexible cable, which comprises a PVC protective inner shell, wherein three groups of cable conduction core bodies are circumferentially arranged in the PVC protective inner shell, each cable conduction core body comprises a cable core body protective inner sleeve, and a plurality of cable conduction cores are uniformly arranged in the cable core body protective inner sleeve. The space between the PVC protection inner shell and the PVC protection outer shell is filled with the glass fiber flame-retardant filler, the flame-retardant mica tape is arranged between the cable core protection inner sleeve and the cable core protection outer sleeve, and the outer wall of the flame-retardant mica tape is wrapped with the flame-retardant mica tape, so that the whole cable has three layers of fire-resistant protection from outside to inside; according to the invention, the PVC protective inner sleeve is arranged in the PVC protective outer sleeve, the conduction characteristic of the cable core protective inner sleeve is prevented from being influenced by fire catching or fire disasters of the cable, and the outer wall of the PVC protective inner shell and the inner side wall of the PVC protective outer shell are coated with the zinc oxide coatings, so that the PVC protective inner shell and the PVC protective outer shell have the characteristic of keeping high flame retardance during combustion.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a fire-resistant and flame-retardant composite flexible cable. Background technique [0002] Flame-retardant cables require the sample to be burned. After the test fire source is removed, the spread of the flame is only within a limited range, and the residual flame or residual flame can extinguish itself within a limited time. Its fundamental characteristic is that it may be burned out and cannot operate in case of fire, but it can prevent the spread of fire. However, thicker fire-resistant and smoke-suppressing layers or multi-layer flame-retardant and smoke-suppressing junction claddings are usually designed in flame-retardant cables, which makes the cables very bulky and less flexible. Contents of the invention [0003] The object of the present invention is to provide a fire-resistant and flame-retardant composite flexible cable, which can maintain the flexibility and ligh...
