Composite string insulator units for overhead lines with a nominal voltage greater than 1000 V - Standard strength classes and end fittings Ingestion-build-251241 The following types of floating1 Scope This part of IEC 61466 is applicable to composite string insulator units for a. c. 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 on electric traction lines. This standard applies to string insulator units of composite type with ball, socket, tongue, clevis, Y clevis or eye couplings, or a combination thereof. The object
