One of the most notable real-world deployments of the 8DN9 is at the , which features the world's tallest dam at 335 meters. In this landmark project, Siemens supplied a set of 8DN9 switchgear for the 220 kV side of the plant, alongside the larger 8DQ1 for the 550 kV side. The 8DN9's robust design was chosen for its ability to protect the power generation and transmission systems against short circuits and overloads, even under the challenging ambient conditions present at such a high-altitude, seismically active location. The switchgear at Rogun was equipped with online monitoring devices to enable automatic remote diagnosis and self-monitoring, ensuring the long-term stability of the plant’s output. The designation "8DN9" could refer to a specific
