Directly-buried laying power cable and manufacturing method thereof

The invention discloses a direct-buried laying power cable and a manufacturing method thereof, and belongs to the technical field of power cables. Comprising a cable core, a belting layer and/or an inner sheath, an outer sheath and a function reinforcing member. The wrapping tape layer and/or the inner sheath are/is wrapped outside the core wire; the outer sheath is formed outside the belting layer and/or the inner sheath, and at least two supporting bodies are uniformly distributed on the outer edge of the outer sheath; and the functional reinforcers are embedded between the two adjacent supporting bodies. According to the invention, the at least two supporting bodies are formed on the outer surface of the power cable, and when the cable is laid, the space between the cable and the inner surface of the cable container and the space between the cables are supported by the supporting bodies, so that air can effectively circulate in gaps of the supporting bodies, the heat dissipation space is increased, the env
