High-strength wear-resistant fire-resistant flame-retardant power cable and preparation method thereof

Abstract

The invention relates to the technical field of cables, in particular to a high-strength wear-resistant fire-resistant flame-retardant power cable and a preparation method thereof, the preparation efficiency of the high-strength wear-resistant fire-resistant power cable is improved, the wear resistance and fire resistance of the power cable are improved, and the practicability is improved. Comprising conductive units, a tightening belt, an inner sheath, an armor layer, a polypropylene fiber layer, a corrugated aluminum sheath, an outer sheath and a filling rope, the tightening belt is wound on the outer walls of the four groups of conductive units, the conductive units are in a quarter sector shape, the tightening belt winds the four groups of conductive units into a cylindrical shape, the inner sheath sleeves the four groups of conductive units, and the armor layer is arranged on the outer wall of the corrugated aluminum sheath. The tight binding belt is located between the conductive units and the inner sheath, the armor layer is woven in a rhombic net shape and sleeved on the outer wall of the inner sheath, the polypropylene fiber layer is sleeved on the outer side of the armor layer, the corrugated aluminum sheath wraps the outer wall of the polypropylene fiber layer, and the outer sheath is sleeved on the outer wall of the corrugated aluminum sheath.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength wear-resistant, fire-resistant and flame-retardant power cable and a preparation method thereof. Background technique [0002] Power cables are cables used to transmit and distribute electrical energy. Power cables are often used in urban underground power grids, power station lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the main lines of the power system; the existing power cables have poor wear resistance and fire resistance, and the production efficiency of power cables is low. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned technical problems, the present invention provides a high-strength...
