ABB DC Prefabricated Rail Substations

ABB has introduced a range of modular and transportable substations for the rail sector designed to offer a reduction in civil works, footprint and land acquisition costs, making them suitable for engineering, procurement and construction management use. They enable fast-tracking power to both new projects and the replacement of existing substations that are due for renewal.

The ABB DC Prefabricated Rail Substations require minimal on-site labour and are quick to install. The designs are flexible and adaptable with the ability to specify between incoming voltage and outgoing power designs, as well as customising the capacity of the unit to suit specific operational requirements.

Three basic rail substation models are on offer including a transportable building DC rail substation with customisable cladding options, a skid-mounted DC rail substation for installation into permanent buildings and a stackable modular design for partial substation refurbishment.

Each unit comes preassembled with medium-voltage switchgear in either 11, 22 or 33 kV, DC switchgear with a rectifier in 750 to 1500 VDC, and a rectifier transformer with variable power options of (1, 2, 3, 4 or 5 MW) and voltage (750 or 1500 V output).

The range is fully self-contained and includes an integrated power supply, which reduces overall risk to a project.
