The utility model discloses an energy-efficient suspension clamp made of a composite material. The energy-efficient suspension clamp comprises a clamp body, a clamp pressure plate, U-shaped bolts, gaskets, nuts and a closed pin. The energy-efficient suspension clamp also comprises hold hoops, a lengthened bolt, cushion blocks and thicken gaskets, the central section of the clamp body is provided with U-shaped grooves used for holding wires along the axial direction, the clamp pressure plate is arranged on the U-shaped grooves, on the clamp pressure plate, the U-shaped bolts traverse screw holes in the clamp body in order and lock the wires through the gaskets and the nuts; the hold hoops hold the clamp body, the two sides of each hold hoop are respectively provided with one cushion block and one thicken gasket, and the lengthened bolt traverses the thicken gaskets, the cushion blocks and the hold hoops in order and is fixedly connected with a screw hole in the clamp body. Beneficial effects of the energy-efficient suspension clamp made of the composite material are that the vertical breaking load of the suspension clamp can be adjusted in dependence on actual designs and working conditions, and the energy-efficient suspension clamp is advantaged by being wide in application range, convenient to install, resistant to corrosion and aging, long in service life, big in safety factor and the like.
