Description

technical field [0001] The invention relates to the technical field of cables, in particular to flame-retardant power cables. Background technique [0002] With the gradual development of the cable industry, cables are used in all aspects of people's lives. During the use of cables, they are often subject to friction and corrosion to varying degrees. For cables used in harsh environments, the cable's Friction resistance, corrosion resistance, insulation, flame retardancy and other properties put forward higher requirements, and the performance of existing cable materials can no longer meet the requirements, so a new cable needs to be proposed. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a flame-retardant power cable, which has good tear resistance, good impact resistance, high mechanical properties, good corrosion resistance, and good flame retardancy. [0004] A flame-retardant p...
