The Siemens 8DN9 is a gas-insulated, metal-enclosed, high-voltage switchgear (GIS) designed for rated voltages up to 245 kV. As part of Siemens Energy's portfolio for power transmission, the 8DN9 was developed as a high-performance, low-maintenance solution for modern energy systems.
Touch-safe outer enclosures ensure that operators can safely walk around the switchgear bay while it is fully energized. Internal arc classification (IAC) testing guarantees that even in the highly unlikely event of an internal fault, gas expansion is safely channeled away from personnel.
