Abstract
The invention discloses a fireproof flame-retardant cable and a manufacturing process thereof. The fireproof flame-retardant cable comprises a main supporting column, a fireproof filling layer, a cable core, a fireproof insulating layer, a fireproof ring, a limiting table and a metal shielding layer; first mounting grooves are formed in the peripheral surface of the main supporting column; the first mounting grooves are arc-shaped grooves, and the multiple first mounting grooves are evenly formed around the central axis of the main supporting column; second mounting grooves are formed in the inner circumferential surface of the fireproof ring; the fireproof insulating layer is arranged on the outer peripheral surface of the cable core, the outer peripheral surface of the fireproof insulating layer is connected with the main supporting column and the fireproof ring, and the fireproof insulating layer is located between the first mounting grooves and the second mounting grooves; the fireproof filling layer is arranged among the main supporting column, the fireproof ring and the adjacent fireproof insulating layers. the limiting table is arranged on the peripheral surface of the fireproof ring; and the metal shielding layer is arranged on the outer circumferential surface of the fireproof ring, and a limiting groove is formed in the inner circumferential surface of the metal shielding layer. The fireproof flame-retardant cable is high in structural strength, good in bending resistance and capable of bearing frequent bending and unfolding, and therefore the fireproof flame-retardant performance of the fireproof flame-retardant cable is guaranteed.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to a fire-resistant and flame-retardant cable and a manufacturing process thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulating covering. The cable has the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables and aluminum alloy cables, etc. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] Under the existing technology, for cables with fire-resistant and flame-retardant ...
