Usual Operating
Conditions
Series 2000 Circuit-Switchers will perform as intended at temperatures within the range of
–40°C (-40°F) to +40°C (104°F) (–35°C (-31°F) to +40°C (104°F) for 161-kV and 230-kV models),
at altitudes of up to 5000 feet (1524m), and at wind loadings of up to 90 miles per hour
(145kmph). Further, Series 2000 Circuit-Switchers, when installed with the recommended S&C
anchor bolts and with flexible-conductor connections at all six terminal pads, are capable of
withstanding seismic loading of 0.2g ground acceleration in any direction as well as performing
as intended during such loading and afterward. For applications at temperatures not within
the specified range, at higher altitudes, at higher wind loadings, or where higher seismic
withstand capabilities are required, refer to the nearest S&C Sales Office.
