NOTE: To determine the section length for an insulator with a different end fitting combination, please add or subtract the displayed length change in the table above. For configurations not shown, use the Catalog Number Key or contact your HPS representative. Dimensional and electrical values displayed in main table are for an insulator with Y-clevis and Ball end fittings. For voltages above 400 kV, other section lengths, or end fitting combinations, please contact your HPS representative. Electrical values are without corona ring. For voltages equal to or greater than 220 kV, refer to page 218 for corona rings and associated physical/electrical changes to the above data. Dimensions are within allowable tolerances as specified by IEC 61109 and ANSI C29.12.
