Abstract

The invention discloses a flame-retardant composite cable, which comprises a cable outer protective layer, a wiring cavity inside the cable outer protective layer, two partitions are symmetrically arranged in the middle of the wiring cavity, and two sets of wiring devices are arranged on both sides of the partition , two sets of wiring devices correspond to a protective bearing, and a protective cavity is opened on both sides of the protective bearing. Each set of wiring devices corresponds to an elastic base film, and a fixed bearing is integrated on the elastic base. The cable core wire is fixed and installed. It is arranged on the fixed bearing bush along the length direction of the outer protective layer of the cable, and one end of the elastic base film extends into the protective cavity and is fixedly connected with the bottom surface of the protective cavity. The cable of the present invention can protect the core wire of the cable and increase the service life and safety of the cable by being stored in the protection cavity when it is under pressure or when a fire occurs.

Description

technical field [0001] The invention relates to the field of cables, in particular to a flame-retardant composite cable. Background technique [0002] Cables are widely used in signal and power transmission. Cables are laid in many fields, such as in the air, indoors and on the ground, but no matter what kind of occasion the cables are laid, they need good flame resistance. There is an external fire or a fire caused by aging and spontaneous combustion, so the current cables need good flame retardant properties. Furthermore, if cables are not laid in the air, they are laid on the ground or underground in many cases, and the amount of laying underground is in the majority, which does not hinder ground traffic. However, after the current cable is buried, its compression resistance is poor, and the damage to the outer protective layer will directly cause damage to the cable core wire, resulting in serious economic losses. Contents of the invention [0003] The technical prob...
