The invention discloses a wire cable with good fire resistance and flame retardance. The wire cable comprises a cable body, a corrosion-resistant layer, a flame-retardant layer, ceramic silicone rubber and steel wire ropes. The ceramic silicone rubber is installed at the center of the interior of the cable body. The steel wire ropes are arranged in the ceramic silicone rubber at equal intervals; arope silk ribbon is wound on the outer edge of the steel wire ropes; a second wire is arranged in the ceramic silicone rubber between the adjacent steel wire ropes, a third wire is arranged in the ceramic silicone rubber above the second wire, a first wire is arranged in the ceramic silicone rubber on one side of the third wire, and a copper wire is installed in the center of the interior of thefirst wire. Better fire-resistant, flame-retardant and high-temperature-resistant performances of the wire cable are realized, the reliability of the wire cable under strong field tension is ensured,and the application range of the wire cable is widened.
Description
technical field [0001] The invention relates to the technical field of wires and cables, in particular to a wire and cable with good fire resistance and flame retardancy. Background technique [0002] Electricity is the energy guarantee for people's life, production, work and study. Electricity is transported to thousands of households through cables. Cables are cables similar to ropes twisted by several wires or groups of wires. Each group of wires is insulated from each other. , and is often twisted around a center, and the entire outer surface is covered with a highly insulating coating. If the current-carrying capacity of the wire and cable exceeds its ultimate carrying capacity, the current is too high and it will cause danger due to heating, but the existing fire-resistant and flame-retardant There are still some shortcomings to be improved when the wire and cable with good performance are used again. [0003] There are a wide variety of such wires and cables on the m...
