GE is bringing generator technology and performance to the next level. We engineer and build our generators to meet the demanding specifications that keep you on the leading edge of efficient, reliable output. Our equipment installs quickly, integrates easily, operates reliably and delivers more power. With over 12,000 generators shipped since 1901, GE understands your challenges, and offers a complete range of configurations and cooling technologies to meet industry needs.

Our validation program is rigorous. Every new product is subjected to endurance and thermal-cyclic testing that simulate one full year of operation. This approach helps ensure that we deliver the world-class reliability you expect.

GE fully integrates engineering, manufacturing and life cycle services to keep your generators operational for the life of the equipment and to provide more value to you.


Modular Generator Architecture

  • Constant cross-section core segments are used to achieve higher product ratings with common designs.
  • Common end components drive greater spare parts efficiency, interchangeability, and maintenance familiarity.
  • One-piece frame and flexible terminal lead arrangements provide ease of installation and reduce plant construction costs.

Armature Systems

  • Micapal*, MICADUR* and DURITENAX* stator bar insulation technologies enable higher power density, advanced voltage stress, and thermal conductivity capabilities for greater armature performance.
  • Robust mechanical features, such as TETRALOC* and self-retightening end winding support systems, allow thermal expansion of the winding during operational transients while simultaneously tightening the winding.
  • Armature slot retention systems to ensure constant pressure on the bars, restraining them from radial and tangential motion during operation. These features include top-ripple and side-ripple springs as well as concave-convex and piggy-back wedging systems.

Water-Cooled Technology

  • Stainless steel armature bar cooling tubes provide a proven method of eliminating the risk of cooling tube clogging, which can result in armature overheating.
  • Advanced phosphorous-free brazed connections help reduce leakage.
  • The high oxygen deionized water system prevents cuprous oxide buildup.
  • Optimized for both rail and road transport. Only a small number of individual parts are transported, which translates into short delivery and faster erection time.
