The present invention relates to a tubular bus-bar jumper structure and a tubular bus-bar supporting armor clamp thereof. The tubular bus-bar jumper structure comprises a tubular bus-bar and two tubular bus-bar supporting armor clamps arranged on the tubular bus-bar, each tubular bus-bar supporting armor clamp comprises a tubular bus-bar clamp connected with the tubular bus-bar, and a fixing baseis connected at the periphery of the tubular bus-bar clamp. A cable fixing structure is arranged on the fixing base and has one or two cable fixing holes which are coaxial front and back, and the axisof the cable fixing hole is inclined. According to the present invention, firstly the axis inclination direction of the cable fixing hole is consistent with the routing direction needed by a cable, the cable does not need to bent or the bending angle of the cable is smaller when the cable enters the cable fixing hole, thereby avoiding a phenomenon that the cable is bent, so that the cable is damaged. In addition, the axis of the cable fixing hole is inclined, and the routing direction of the cable can be guided, so that the cable jumper is realized without needing to set a higher height, andaccordingly, the volumes of the tubular bus-bar supporting armor clamps and the costs of the tubular bus-bar supporting armor clamps are reduced.
