ABB’s new fast-deployable transformer with hybrid insulation of DuPont™ Nomex® combines an exceptionally high power/voltage rating of 250 MVA, 400 kV with significant size and weight reduction for rapid transport mobility and fast deployment.
ABB, partnering with the U.S. Department of Homeland Security (DHS), delivered three modular transformers from its St. Louis, Missouri facility to a Texas substation within 20 hours in an emergency drill. These transformers designed with DuPont™ Nomex® high-temperature insulation can be shipped and fully energized in less than a week.
The use of Nomex® paper and pressboard helps enable a lighter weight traction transformer design for Amtrak’s Acela Express, reducing the weight of the equipment transformer by between 15% and 25%.
Yunnan Transformer Co. met reliability needs under extreme overload using Nomex® paper in liquid-immersed transformers with hybrid insulation systems.
Transformer retrofit with Nomex® insulation boosts operational flexibility, enhances reliability under demanding operating conditions and reduces maintenance costs for hydroelectric power plant.
Niagara Mohawk Power Corporation turned a mobile transformer failure into success by opting for a transformer uprating with Nomex® paper and pressboard, increasing capacity and versatility for less than half the cost of a new unit.
In 2000, CG Power Systems teamed up with DuPont to develop high-temperature, liquid-immersed transformers targeted at the wind segment. Today, thousands of wind turbine transformers with Nomex® insulation have been installed globally.
