As the world's leading supplier of substation equipment, from deserts and mountains to offshore platforms and city centers, ABB offers leading-edge technologies to increase the reliability and flexibility of power transmission and distribution systems in these most demanding environments. ABB has been manufacturing substation equipment since the early 1900s and has so far participated in more substation projects than any other supplier worldwide. For decades, ABB's innovations have revolutionized substation technology in key aspects such as equipment size, performance and intellectual sophistication. E.g: In 1965, ABB provided the world's first gas-insulated (GIS) substation. GIS technology will reduce the substation footprint up to 70%, amazing changes, the equivalent of a football field reduced to a small garden. In this way, we can build substations in the city center and in places where space is limited, such as offshore rigs, power plants and office buildings. For more than 40 years ABB has delivered tens of thousands of GIS equipment worldwide, including the largest GIS plant in the world - Brazil's Itaipu Hydropower Station (delivered in 1984 with a rated voltage of 550kV) and China Three Gorges Hydropower Station (delivered in 2006, Rated voltage 550kV). Recently, ABB and China National Grid Corporation (SGCC) have collaborated to raise the world record of the rated voltage of GIS switches to 1,100 kV. This technological innovation allows SGCC to build the world's most powerful long-distance AC power transmission network in the coming years. In addition, ABB has developed unique innovations such as isolated circuit breakers and air-insulated / gas-insulated hybrid switching devices, setting new records in the size and performance of air-insulated substations. The DCB combines all the features of a circuit breaker with a disconnector , while a traditional solution requires three components (two separate switches for each circuit breaker). ABB has recently increased the rated voltage of its circuit-breakers to 500 kV, making it possible for the first time to build UHV AIS substations and power hubs near city centers. Often, it is difficult to build large AIS substations in these land-scarce areas. The design of the 500kV isolation circuit breaker shrank the footprint of a large 500kV AIS substation from approximately 60,000 square meters (equivalent to 6 football pitches) to about 30,000 square meters. The resulting savings in installation and construction costs as well as changes in visual effects are enormous. The introduction of the IEC 61850 substation communication standard is one of the strongest advances in substation automation and protection technology over the past decades as it addresses the longstanding long history of establishing uniform global standards for substation automation equipment interconnection, real-time communications and data exchange The problem. ABB played an important role in the development of this global standard and installed the world's first multi-vendor interworking system based on IEC 61850 in 2004, one of the largest and most important substations in Europe. For the past four years, ABB has provided hundreds of IEC 61850-based systems and thousands of devices to new substations and substation projects in more than 60 countries around the world to enhance the performance, efficiency and reliability of these substations.
