Abstract
The invention discloses a special cable for public facilities. The special cable comprises a cable core, a polyester enameled wire layer, a glass ribbon layer, a copper wire layer and a sheath layer, wherein the polyester enameled wire layer wraps the cable core and is filled with kaolinite powder, a rhombic PVC support rack is arranged in the polyester enameled wire layer, the glass ribbon layer wraps the polyester enameled wire layer, the copper wire layer wraps the glass ribbon layer, and the sheath layer wraps the copper wire layer. The special cable for the public facilities has the advantages that the cable is novel in structure, excellent in low-temperature resistance, high-temperature resistance, acid-base corrosion resistance, ozone aging resistance and ultraviolet irradiation resistance, resistant to termites, mice, dampness, mildew and the like, insulating, fireproof, long in service life, and applicable to the power supply connection of city water supply and draining facilities, sewage facilities, road facilities, bridge facilities, tunnel facilities, subway facilities, square facilities, scenic spot facilities, environment facilities and the like and the power and control connection of electrical equipment.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to a special cable for public facilities. Background technique [0002] There are strict requirements for the power connection of municipal engineering such as urban water supply and drainage, sewage, roads, bridges, tunnels, subways, squares and tourist attractions, and environmental facilities, and the cables used for power and control connections of electrical equipment. Existing cables are widely used, but conventional cables are still difficult to meet the ideal requirements for comprehensive performance such as high temperature resistance, low temperature resistance, corrosion resistance, flame retardancy, waterproof, fire prevention, and non-cracking applications. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a special cable for public facilities with a novel structure and excellent cold r...
