Nomex® for Generator Insulation Helps Extend Equipment Life
From small generators used in wind turbines to very large turbo generators, the use of DuPont™ Nomex® brand papers and Nomex® based laminates for generator insulation helps improve reliability.
Generator insulation is a small but critical component that plays a major role in determining the reliability and service life of a generator. Choosing Nomex® as generator insulation helps increase reliability, prevent premature failure and extend generator service life.
The outstanding thermal performance, excellent dielectric strength and mechanical toughness of Nomex® are the reasons why it is an ideal choice as generator insulation for all sizes of generators used in a broad range of applications.
Exceptional Thermal Protection
The use of Nomex® for generator insulation can help prevent premature failure and equipment downtime. That’s because Nomex® does not shrink, embrittle, soften or melt during short-term exposure to temperatures as high as 300°C, and because it maintains good insulating properties continuously at 220°C for 10 years.
Excellent Dielectric Strength
Nomex® insulation features excellent electrical properties, even when exposed to environmental conditions such as high humidity.
Superior Mechanical Toughness
The excellent mechanical strength and resilience of Nomex® insulation help extend the service life of generators subjected to harsh operating conditions, such as the abrasion caused by thermal expansion and centrifugal forces in standby gas-turbine generators.
Typical Applications in Generators
Nomex® papers and Nomex® based laminates are used in generators such as:
- Slot insulation
- Wedges, midsticks
- Phase insulation
- Conductor insulation
- Coil separators
- OCT Tape
- Pole insulation
- Turn insulation
- Main wall insulation
Typical Generator Equipments
Nomex® papers and Nomex® based laminates are used in virtually all types of generators, including:
- Turbo generators
- Hydro generators
- Low voltage generators
- High voltage generators
- Wind generators
The unique combination of Nomex® paper properties provides proven reliability, making Nomex® an ideal electrical insulation material of choice for manufacturers of transformers, generators, motors and other electrical equipment.
