Composite string insulator units for overhead lines with a nominal voltage greater than 1 000 V - Dimensional and electrical characteristics Ingestion-build-47786 This National Annex gives: the1 Scope This part of IEC 61466 is applicable to composite string insulator units with a specified mechanical load (SML) of 40 kN to 600 kN for AC overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to insulators of similar design used in substations or for railway applications. This standard applies to string insulator units of composite type with fittingsin accordance with IEC 614661.
