“…Wire ropes are often used for the vibrational control of industrial equipment [32]. They have never been used in practical applications as seismic isolators that have only been demonstrated in research studies [8,35,4,9,23,16,18,17]. The outcome confirmed that wire rope isolators are the suitable isolation system to mitigate the response of HV equipment to earthquakes.…”

“…Similar effects were recorded during the 1999 Itzmit, 1999 Chi Chi, 2003 Bahm, 2010 Christchurch and 2010 Tohoku earthquakes [11,31,16,14,20]. Based on work by Schiff [30], Anagnos [2] developed a database for electrical substation equipment performance that contains information on the damaged and undamaged components from 12 California earthquakes (from the San Fernando Earthquake in 1971 to the Northridge Earthquake in 1994).…”

“…The seismic vulnerability of High Voltage (HV) equipment installed in electric substations within power transportation and distribution networks has been clearly shown during recent destructive earthquakes [1][2][3][4]. This is not surprising because many of these equipment are slender, with heavy masses placed at top and mostly composed by porcelain, a material with a good strength but extremely brittle.…”

“…Poor seismic performance of these system components could result in extended power outages that might propagate far beyond the local epicentral region. Knight and Kempner, Jr. (2009) [5] …”
