High-strength and light cable bridge rack

The utility model discloses a high-strength and light cable bridge rack which comprises side plates (3) and a bottom plate (7), and is characterized in that the high-strength and light cable bridge rack is a one-piece structure with an open upper mouth, the side plates (3) are provided with connection holes (1) and grounding holes (2) and serve as strengthening side plates, crosswise ribs (4), lengthwise ribs (5) and heat dissipation holes (6) are disposed on the bottom plate (7), and the heat dissipation holes (6) are formed through lower punching without causing any burrs inside the bridge. The advantages and effects of the high-strength and light cable bridge rack are that through plate and geometrical shape changes and optimized arrangements of the lengthwise ribs and the crosswise ribs on the bottom plate, mechanical strength and overall rigidity of the products is raised and materials are saved by 30 %; the lower punching is adopted to the punching holes, and causes no burrs inside the bridge rack, ther
