A vibration-controlled elastic bearing with steel spring laminated rubber sheet is provided, comprising an upper connecting plate, a lower connecting plate, and a damping body. Multiple vertically arranged damping springs for absorbing vibration energy are evenly distributed inside the damping body. The upper and lower ends of the damping springs, which penetrate the damping body, are respectively connected to the upper and lower connecting plates via an upper sealing plate located above the damping body and a lower sealing plate located on the lower end face of the damping body. This invention optimizes the internal structure of the elastic bearing to achieve dual vibration control, ensuring reliable damping while improving the load-bearing capacity for large shear forces. It solves the pollution problem associated with traditional core rubber seismic isolation bearings. While the damping springs bear the main dynamic load, it reduces fatigue damage to the damping body, lowers its aging rate, and extends its service life.

This invention discloses a weather-resistant enhanced 1kV overhead insulated conductor, relating to the field of power cable technology.
