The evolution of air-insulated switchgear and components
For more than 120 years now, ABB has been supporting society's need for electricity by developing the safest, most reliable and affordable products, solutions and services for the delivery of electrical power. A core element is the company's high-voltage (HV) air-insulated switchgear (AIS). Its development throughout the years has been characterized by functionally focused design, utilization of the most appropriate materials according to their purpose and the quest for simplicity in design. This has led to inherent robustness, minimal material use and lowest operational power losses.
