Applies to fittings for overhead lines of nominal voltage above 45 kV. It may also be applied to fittings for overhead lines of lower nominal voltage and to similar fittings for substations. The contents of the corrigendum of September 1998 have been included in this copy.Although created for fittings above 45 kV the standard may also be applied to lower voltages and to similar fittings for substations.<\/p>\n
