Zurich, Switzerland, June 17, 2015 – Full range of UniGeardigital switchgear enables flexibility, energy efficiency and operating costsavings
ABB, the leading power and automation technology group, isshowcasing a full range of UniGear Digital medium-voltage (MV) air-insulatedswitchgear for primary substations at the CIRED conference in Lyon, France.Running from June 15-18, 2015, the biennial global event is a key platform toshowcase technologies, discuss market trends and future developments in thepower distribution sector.
The UniGear concept combines proven switchgear design with aninnovative approach to protection, control, measurement and digitalcommunication. It is based on the optimized integration of current and voltagesensors into MV switchgear, combined with the latest intelligent electronicdevices (IEDs) and IEC 61850 open communication capability.
“This is yet another example of how ABB differentiates itselfthrough technology and innovation,” said Bruno Melles, head of ABB’s MediumVoltage Products business, a part of the company’s Power Products division. “Aspart of our Next Level strategy, we continue to support our customers andfacilitate a safe, flexible, eco-efficient and smart power distributionnetwork.”
UniGear Digital is based on a “one size fits all” concept, whichmeans there is no need to change primary MV components if the load changes,saving time and money during project planning and execution. As well as takingup less space in the substation, UniGear Digital has fewer live parts, sooutages are less frequent and troubleshooting effort is reduced.
Furthermore, energy losses during operation are lower than withequivalent switchgear: Instrument transformer losses are eliminated and thiscan save around 250 megawatt-hours over the 30-year life of a typicalsubstation with 14 UniGear ZS1 panels as an example. This represents areduction of about 150 tons in CO2 emissions, equal to the emissions producedby a mid-sized European car driven for 1,250,000 kilometers.
More than 500,000 UniGear panels are installed in over 100countries, used in demanding locations such as offshore platforms, liquefiednatural gas (LNG) or cruise ships and mines, as well as in the more commonapplications, like in the manufacturing industry, utility substations, powerplants, chemical plants, data centers, wind farms and major sporting venues.
The UniGear Digital concept is now implemented across the wholesingle busbar portfolio of UniGear up to 24 kilovolts, and is available inUniGear ZS1 12, 17.5 and 24kV, UniGear 550, UniGear 500R and also UniGear MCC.The concept was first embodied in the UniGear ZS1, introduced last year.
