The invention relates to a power communication transmission bridge which comprises a plurality of parallel supporting rods. A number of U-shaped connection rods are arranged on the support rods. The bottom rods of the U-shaped connection rods and the supporting rods form a grid-like supporting surface. The diameter of each bottom rod and the diameter of each supporting rod are the same. The distance between two adjacent bottom rods and the distance between two adjacent supporting rods are equal to each other. A bent plate is detachably arranged on the grid-shaped supporting surface. The bent plate comprises a flat plate and a curved bent part bent downward. Two mounting seats are arranged at the bottom of the flat plate along the length direction. A clamp groove which adapts to a supporting rod/bottom rod is arranged on each mounting seat. The first side wall of each clamp groove is provided with a connection plate, wherein the connection plate is rotatably connected with the first side wall, and the other end of the connection plate is detachably connected with the second side wall of the clamp groove. According to the invention, a cable can extend downward at any position along a curved bent part; the power communication transmission bridge is easy and convenient; the cable is not damaged; the service life of the cable is improved; and the safety and convenience of cable laying are improved.
