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%.
For more than 30 years, Brithinee Electric has been building customer confidence and business growth with an uncompromising demand for quality and exclusive use of Nomex® insulation to meet its electric motor repair requirements.
Flanders Electric provides the highest quality power products and services, including industrial motor repair. An integral part of the quality equation is the use of Nomex® paper and Nomex® based laminates.
Yunnan Transformer Co. met reliability needs under extreme overload using Nomex® paper in liquid-immersed transformers with hybrid insulation systems.
FMV, a designer and manufacturer of industrial ventilators, improved reliability and doubled the service life of its asynchronous motors by upgrading to a Class F motor insulation system with Nomex® based laminate type NM.
The winding wire primary insulation system hinges on Kapton® FN polyimide film. Very, thin yet very resistant, Kapton® ensures extended functionality and longevity of the engines.
Aircraft insulation systems must meet rigid industry requirements regarding fire resistance, durability and weight. The ability of Kapton® polyimide film to withstand both high and low temperature extremes makes it an excellent material for use in space satellite applications.
Kapton® polyimide film provides high temperature durability together with a thin insulation making it possible to use more copper in the motor, thus allowing more power and increased reliability.
Operating for 24 hours a day, the reversing mill with regenerative braking puts excessive strain on the insulation system, Kapton® used as the conductor insulation keeps the mill running.
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.
ABB selected Nomex® paper to help improve the reliability and thermal performance of its substation power transformers.
Whether it’s motor repair, rotor rebuilding, replacement laminations or stator restacking, Darby Electric relies on Nomex® paper and laminates for slot insulation and other critical applications to ensure quality that exceeds customer expectations.
