Scope

This International Standard applies to fittings for overhead lines of nominal voltage above 45 kV. Fittings concerned particularly are all fittings except those that have a specific standard dedicated like spacers (IEC 61854), dampers (IEC 61897) and end fittings for insulators (IEC 61466-1). It may also be applied to fittings for overhead lines of lower nominal voltage and to similar fittings for substations. Moreover, fittings designed for use with High Temperature (HT) conductors are included.In some cases, test procedures and test values are left to agreement between purchaser and supplier and are stated in the procurement contract. The purchaser is best able to evaluate the intended service conditions, which should be the basis for establishing the test severity.In Annex A, the minimum technical details to be agreed between purchaser and supplier are listed.
