— H I G H V O LTA G E P R O D U C T S Gas-insulated switchgear ELK-14 C, 245 kV High performance in a small footprint ABB is the pioneer in gas-insulated switchgear (GIS) technology with over 50 years of proven experience. With a wide range of GIS products up to 1200 kV, we provide reliable and eco-efficient solutions for transmission and distribution grids, power plants and industries. — GIS ELK-14 C, 245 kV double busbar configuration ELK-14 C is the next generation GIS designed to reduce complexity, life cycle costs and environmental impact. The compact design fits in all types of installation environment and offers convenient operation and serviceability. The ELK-14 C is the ideal solution for reliable energy supply up to a rated voltage of 245 kV, a rated current up to 3150 A and a rated short-circuit current up to 50 kA. It comes in a compact design and is fully factory assembled and tested. It is shipped as one bay with all secondary cabling and local control cubicle instead of many assembly units. This delivers significant reduction in installation and commissioning time compared to conventional designs. Benefits • Compact design reduces infrastructure costs and environmental impact • Eco-efficient, small, lean three-phase enclosure with single-phase circuit-breakers • Front access to bays provides easy operation and serviceability • Low life cycle and maintenance costs • Enables integration into mobile prefabricated housing • Advanced features for digital substation • Reliable, well-proven technology based on five decades of experience ELK-14 C, 245 kV Product-ID 1HC0071250M0170 Rated voltage kV 245 / 253 50 / 60 Rated frequency Hz Rated short-duration power-frequency and voltage (1 min) kV 460 Rated lightning impulse withstand voltage (1.2/50 µs) kV 1050 A 3150 Rated nominal current – busbar / feeder Rated short-time withstand current (up to 3 s) kA 50 Rated peak withstand current kA 135 Circuit-breaker mechanical endurance class (10,000 CO) M2 Circuit-breaker capacitive switching class (k = 1.4) C2 Ambient temperature range °C -30 … +50 Installation indoor/outdoor/offshore 7 6 11 4 4 5 5 9 3 3 10 8 1 2 6. — ABB Ltd High Voltage Products Gas-insulated switchgear abb.com/highvoltage Circuit-breaker Operating mechanism Current transformer Maintenance earthing switch Busbar module with integrated disconnector Disconnector switch (exit) — We reserve the right to make technical changes or modify the contents of this document without prior notice.
