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.

Abstract

The invention belongs to the technical field of cables, and discloses a fire-resistant and flame-retardant composite flexible cable, comprising a PVC protective inner shell, and three groups of cable conducting cores are arranged in a circle in the interior of the PVC protective inner shell, and the cable conducting cores include a cable core body protection The inner sleeve, the inner sleeve of the cable core protection inner sleeve is evenly arranged with multi-strand cable guide cores, the present invention is filled with glass fiber flame retardant fillers between the PVC protection inner sleeve and the PVC protection outer sleeve, and the cable core protection inner sleeve and the cable core protection inner sleeve. A flame-retardant mica tape is arranged between the protective jacket of the cable core and a flame-retardant mica tape is wrapped on the outer wall of the flame-retardant mica tape. The whole cable has three layers of fire-resistant protection from the outside to the inside to prevent the cable from being damaged by its own fire or fire. Affects the conduction characteristics of the inner sheath of the cable core protection. Through the zinc oxide coating applied to the outer wall of the PVC protective inner casing and the inner side wall of the PVC protective outer casing, the PVC protective inner casing and the PVC protective outer casing have the ability to keep high when burning. Flame retardant properties.

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] The flame-retardant cable requires 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 burning can be extinguished within a limited time. Its fundamental feature is that it may be burned out and cannot operate in a fire situation, but it can prevent the spread of the fire. However, in the flame-retardant cable, a thicker fire-resistant and smoke-suppressing layer or multiple layers of flame-retardant and smoke-suppressing cladding is usually designed, which makes the cable very bulky and reduces flexibility. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a fire-resistant and flame-retardant composite flexible cable, which can maintain the flexibili...
