Composite cable for fire prevention

Abstract

The invention relates to the technical field of composite cables, in particular to a fireproof composite cable, which comprises an outer protection part for protecting the cable, an inner protection part is sleeved in the outer protection part, the inner protection part comprises an inner sheath, a reinforcing part is sleeved in the inner sheath, and a plurality of supporting parts are arranged between the reinforcing part and the inner sheath. The outer wall of the reinforcing part is provided with a plurality of concave parts used in cooperation with the supporting parts, a plurality of cable cores are arranged in the reinforcing part in a sleeved mode, and a reinforcing core is arranged in the reinforcing part; the reinforcing part comprises a multilateral sheath, and a center sleeve is sleeved at the center line position in the multilateral sheath. The purpose of improving the physical strength of the composite cable is achieved, the compression resistance, tensile resistance, deformation and distortion resistance and stress resistance of the composite cable can be improved, the phenomenon that the cable is damaged due to laying can be avoided, meanwhile, the protection effect on the cable core is improved, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of composite cables, in particular to a composite cable for fire prevention. Background technique [0002] In the application of composite cables, flame-retardant and fire-resistant rubber materials are used as sheaths, so they have excellent fire-proof performance. However, in the application of composite cables with fire-proof properties, the strength of the cables themselves is not high, and it is easy to be laid and long-term Damage occurs during the use of time, so the sheath as a protective function cannot play a corresponding role, so that the cable core is exposed to the external environment, which makes the aging of the cable more serious and seriously shortens the service life of the cable. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a composite cable for fire prevention, which achieves the ...
