ABB Rapid Recovery Transformers: Insulation by Nomex®, Innovation by ABB Case Study
ABB, partnering with the U.S. Department of Homeland Security (DHS), the Electric Power Research Institute (EPRI) and CenterPoint Energy, delivered three modular transformers from its St. Louis, Missouri, facility to a Texas substation within 20 hours in an emergency drill. These “spare tire” transformers, designed with DuPont™ Nomex® high-temperature insulation can be shipped and fully energized in less than a week.
ABB's first 250 MVA, 400kV fast-deployable transformer uses Nomex® Case Study
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.
Brithinee Electric Motor Repair
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.
DuPont™ Nomex® Pressboard Introductory Data Sheet
Nomex® pressboard is comprised of multiple layers of Nomex® floc and fibrids pressed together in board form. The result is a rigid, yet resilient material with excellent thermal stability and dielectric strength.
DuPont™ Nomex® Pressboard Technical Data Sheet
DuPont™ Nomex® pressboards are available in a range of densities to meet the specific needs of your application.
Niagara Mohawk Power Transformer Case Study
At the typical operating temperatures of electrical transformers, Nomex® will not turn brittle. It outperforms cellulose at elevated temperatures and has a much longer lifespan. The superior mechanical toughness of Nomex® paper and pressboard enables windings to withstand the most severe mechanical shocks.
Nomex® 356 - Technical Data Sheet
Nomex® 356 is a medium-density paper that exhibits properties that are midway between high-density Nomex® 410 paper and low-density Nomex® 411 paper. Nomex® 356 is designed for use as layer insulation within transformers and as phase insulation in hand-wound motors, with layer insulation in liquid immersed transformers being one of the best applications.
Nomex® 410 - Technical Data Sheet
Nomex® 410 is a family of insulation papers that offer high inherent dielectric strength, mechanical toughness, flexibility and resilience. Nomex® 410, the original form of Nomex® paper, is widely used in a majority of electrical equipment applications.
Nomex® 818 - Technical Data Sheet
Nomex® 818 is designed for high-voltage applications, including motor conductor and coil wrap, transformer ground and layer insulation. It is a calendered product with high inherent dielectric strength (700 V/mil to 1,000 V/mil [30 kV/mm to 40 kV/mm]), which can be readily impregnated with varnishes where this is desirable.
Nomex® 910 - Technical Data Sheet
DuPont™ Nomex® 910 is a unique insulating material comprised of high quality electrical grade cellulose pulp and web-like binders made from the same high temperature polymer as other Nomex® brand papers.
Nomex® 926 - Technical Data Sheet
DuPont™ Nomex® 926 is a strong, high dielectric, thermally stable paper that is specifically designed for use as conductor insulation in liquid immersed transformers. Nomex® 926 is not appropriate for use as conductor insulation for dry type transformers.
Nomex® 994 PSB - Technical Data Sheet
Nomex® 994 PSB is a densified, rigid board which has a unique combination of superior resistance to compression, even at elevated temperatures, along with relatively high oil absorption characteristics.
Nomex® Paper & Pressboard - Technical Data Sheet
Nomex® Paper - Moisture Effects and Processing Information
With increasing trends to tighter tolerances and process optimization, the issue of moisture absorption by DuPont™ Nomex® brand paper and the effect on its properties needs to be explained.
Nomex® Paper - Technical Data Sheet
Chemically, Nomex® paper is an aromatic polyamide and is generally known as an aramid. The molecular structure of the material is particularly stable and the properties of Nomex® paper are a consequence of this.
Nomex® Paper and Pressboard - UL Yellow Card Information
The UL Yellow Card displays the key information for UL Recognized materials, based on testing according to UL Standards. The following tables show this information for NOMEX® brand paper and pressboard products when tested per the noted Standard. Areas in the tables with no data have not been tested.

UL Recognized 600 Volt Class based on Nomex® System
To make safe and reliable electrical equipment, manufacturers must use an insulation system which lasts throughout the useful life of the equipment while protecting the lives and property of the users. Underwriters Laboratories Inc. (UL), an internationally respected safety agency, develops, publishes, and enforces safety standards for insulation systems and equipment, and since 1894, users have relied on the UL “Listed” or “Recognized” marks to confirm that rigorous safety standards and procedures have been used in producing equipment they purchase.
