The invention discloses a high voltage transmission power cable which comprises four cable cores. The sections of three cable cores exactly form a circular ring, and the section of the other cable core is in a circular shape. The cable core with the circular section is located inside a cavity formed by the other three cable cores. An insulating layer and a shielding layer are arranged outside the cable core with the circular section in sequence from inside to outside. The outer surfaces of the three cable cores with the sections forming the circular ring are each provided with an insulating layer. A waterproof layer and a protecting layer are arranged outside the three cable cores with the sections exactly forming the circular ring in sequence from inside to outside. The high voltage transmission power cable further comprises a first wire, a second wire and a third wire. The outer diameter of the first wire, the outer diameter of the second wire and the outer diameter of the third wire are tangent in pairs. The first wire, the second wire and the third wire are arranged in the protecting layer and are parallel to the cable cores. The steal site can be known immediately when a thief steals the power cable protecting layer.
