Interference-resistant and fire-proof power cable

Abstract

The invention discloses an interference-resistant and fire-proof power cable. The interference-resistant and fire-proof power cable is composed of a copper-clad steel armoured layer, an outer fluororubber sheath and main cable cores, wherein polyvinyl chloride insulation layers are wrapped on a plurality of strands of silver-plated copper wire stranded conductors in an extruded mode to form the main cable cores, and a square inorganic fiber inner core is tightly wrapped with the four main cable cores in an extruded mode; each of four shielding cable cores is arranged in an outer gap between every two main cable cores making contact with each other; the four main cable cores and the four shielding cable cores are wrapped with a ceramic silicone rubber wrapping layer to form a total cable core; a gap of the total cable core is filled with silicon carbide composite material filler; the copper-clad steel armoured layer is arranged outside the total cable core; the outer fluororubber sheath is wrapped on the copper-clad steel armoured layer in an extruded mode. The cable is suitable for being laid underground, and is light in weight, high in structural strength, resistant to high temperature and fire, excellent in interference resistance, and good in shielding performance.

Description

technical field [0001] The invention relates to the field of cables, in particular to an anti-interference fire-resistant power cable. Background technique [0002] With the rapid development of the national economy, as the main artery of the national economy, the amount and scope of wire and cable are becoming larger and larger. In recent years, power plants, substations, smelting and petrochemical industries have had a huge demand for cables. At present, there are a variety of cables on the market, and they are used in a variety of different occasions. However, most of the cables have some problems. For example, in the event of a fire, the cables are easily damaged by heat, which affects the overall operation of the cables, and the signal shielding performance is weak, the anti-interference performance is poor, and the stable operation cannot be continued for a long time. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects of the prior ar...
