ABB won orders worth $45 million from Svenska kraftnät, the Swedish National Grid operator, to supply three 400 kV substation to strengthen the Swedish power grid. The substations are scheduled to be commissioned in 2015. ABB's project scope includes the design and supply of engineered packages for the high-voltage air-insulated switchgear (AIS) substations. Key products and systems to be supplied cover a range of high-voltage equipment including a combined disconnector circuit breaker (DCB).This DCB integrates the disconnecting function into the circuit breaker and eliminates the need for two separate free-standing disconnectors. The substations will also be equipped with IEC 61850 based open control and protection systems and equipment.
