The invention belongs to the power grid auxiliary equipment field and relates to a cable, in particular to a high temperature-resistant and ageing-resistant cable. The high temperature-resistant and ageing-resistant cable comprises a cable core for election conduction; and the cable core is sleeved with an insulation layer for high temperature resistance of the cable, a flame retardant layer for flame retardance of the cable, a durable layer used for ageing resistance of the cable, and a light reflection layer for improving the reflectivity of the surface of the cable. Compared with the prior art, and according to the high temperature-resistant and ageing-resistant cable of the invention, the sheath of a traditional cable is designed into a layered structure instead of an integrated structure, and each layer has different functions according to positions where the corresponding layers are located, and therefore, the overall ageing-resistance, the temperature resistance, and weather resistance of the cable can be improved. The high temperature-resistant and ageing-resistant cable is simple in structure, highly available in raw materials, and suitable for large-scale use.
