A pressure-resistant and anti-aging cable is provided to address the technical problem mentioned in the background art: existing cables lack a pressure-resistant structure, making them susceptible to compression and bending during construction or use, leading to insulation cracking or even conductor breakage, causing short circuits or leakage faults. The cable core includes an insulation layer covering its outer wall, a first protective layer covering the outer wall of the insulation layer, a second protective layer on the outer wall of the first protective layer, and several ring-shaped, equidistantly distributed air pockets for buffering between the first and second protective layers. A pressure-resistant inner tube is located on the outer wall of the second protective layer, and a pressure-resistant outer tube is located on the outer wall of the pressure-resistant inner tube. Several ring-shaped, equidistantly distributed support rods are fixed between the pressure-resistant inner tube and the pressure-resistant outer tube, and a pressure-resistant component is provided between adjacent support rods to improve the pressure resistance of the pressure-resistant outer tube.
