The invention discloses a flame-retardant compression-resistant cable which comprises a cable core. The flame-retardant compression-resistant cable is characterized in that: the cable core is formed by stranding of a plurality of conductors which are coated by an insulation layer; outside of the cable core is coated with a wrapping tape layer; outside of the wrapping tape layer is coated with a shielding layer; outside of the shielding layer is coated with a flame-retardant layer; outside of the flame-retardant layer is covered with a buffer layer; and outside of the buffer layer is coated with a protective layer. The invention has the advantages that: the flame-retardant compression-resistant cable is simple in structure, good in performance, low in cost, safe in operation, convenient in use, better in cable performance, and better in flame-retardant compression-resistant property of the cable, so that the cable is more convenient and reliable in use; and the accident caused by the misconduct in the construction and installation process is prevented.
Description
technical field [0001] The invention relates to the field of cables, in particular to a flame-retardant and pressure-resistant cable. Background technique [0002] At present, with the development of society, the power consumption is also increasing, which requires the current carrying capacity of the cable to be larger and higher, and the performance requirements of the cable are higher and higher. The cable is usually a rope-like cable twisted by several or several groups of wires, and each group is twisted with at least two wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a highly insulated overlay. However, the flame retardant and pressure resistance performance of cables is poor at present, especially the cables cannot have any problems during use, and a single cable structure can no longer meet the diverse requirements. [0003] Therefore, there is an urgent need for an improved tec...
