Technologies Bring Added Value

GE’s generators use efficient technologies and contain features that save customers both time and money.

Our technologies are based on many years of proven experience and continuous customer feedback, and are often shared among different product families. Here are three examples. 

Stainless Steel Tubes

Used on GIGATOP 4-Pole and GIGATOP 2-pole generators

The cooling tubes in the stator winding of GE’s GIGATOP 2-pole generator are made of stainless steel, so they can’t corrode. Stainless steel additionally eliminates the risk of clogging leading to an unplanned forced outage. GE is the only manufacturer to offer this feature.

Self-Retightening End-Winding Support

Used on TOPAIR, TOPGAS, GIGATOP 4-Pole, and GIGATOP 2-pole generators

GE’s generators have self-retightening end-winding support, which allows thermal expansion of the bars while simultaneously tightening the winding in radial and tangential directions.This system saves maintenance time, avoids forced outages, and increases plant availability on the grid.

Concave-Convex Wedges

Used on TOPAIRTOPGASGIGATOP 4-Pole, and GIGATOP 2-pole generators

The concave-convex wedges used in GE’s generators have a unique design that sustains pressure on the stator bars. This constant pressure prevents radial movements of the winding, avoiding a forced outage from insulation breakdown, while cutting maintenance hours and increasing plant availability.
