Insulation System
The reliability of our insulation systems
are validated through a combination
of rigorous qualication testing and
service life experience.
Our insulation system ensures long life
and reliability by meeting the stringent
mechanical and thermal requirements
of a wide range of challenging
specications.
Our system is comprised of specially
engineered materials selected for
thermal capability, high dielectric
strength, electrical reliability and
chemical resistance. The system
then undergoes a Vacuum Pressure
Impregnation (VPI) process for added
protection and rigidity.
Acceptance Testing
Tests are made during the
manufacture of the windings to
assure that each machine meets
critical material and manufacturing
quality standards. Additional tests are
available to assure the machines meet
unique functional, environmental or
even regional requirements for every
application.
Superior Construction
Stator Frame
and Magnetic Core
• Low Loss Core Design
• Easy Access for Routine
Maintenance
• Low Vibration – Long Life
Our stator frame has been optimized
utilizing advanced nite element
analysis tools. Over the decades, these
structures have been proven to comply
with the most demanding industry
standards and requirements.
The stator core is made up of low
loss, high grade electrical sheet steel
insulated with an inorganic coating. By
combining high performance materials,
well-proven design techniques and
modern manufacturing tools, we are
able to oer some of the most compact
and ecient designs in the industry.
