PCORE Electric Co. announces a stronger 500-kV oil-filled porcelain bushing. Recently, PCORE conducted the highest level of the time history shake table test on a 500-kV/1675-kV BIL POC Series II bushing. During the test, the bushing was shaken at an acceleration of
2.5 g (25% higher than the required value for high seismic performance), where the top of the bushing experienced an acceleration of more than 8.0 g. The bushing successfully passed the time history shake table test. To see the video, visit www.youtube.com/watch?v=GVvf-ZwAs48.
