Extending Vibration Isolation to New Fields
– Nuclear Power Plant Seismic Resistance
Seismic isolation bearings and dampers placed under the nuclear island or key equipment lengthen the natural vibration period, detuning it from earthquake excitation frequencies. This dissipates seismic energy, greatly attenuates shock loads, and improves the plant's seismic safety.
Vibration isolation of power transmission and distribution equipment
Using isolators, isolated foundations, and damping measures—attenuates vibrations caused by earthquakes, fans, and short-circuit faults in busbars. This protects transformers, switchgear, reactors, and other equipment from damage, preventing structural failure, oil leakage, power outages, and loss of electrical connectivity.
