Designed for

>60% efficiency in combined cycle and best in class

operational flexibility

SGT5-8000H Efficient & Flexible

4 stages of fast acting variable-

pitch guide vanes (VGV) allowing

for

improved part load efficiency and high load transients

Proven rotor design (Hirth

serration, central tie rod, internal cooling air passages) for world class fast (cold) start and

hot restart capability

High cycling capability

due to fully internally air cooled

turbine section

Evolutionary 3D blading

3D Four stage turbine with advanced materials and thermal barrier coating

HCO for reduced clearance losses

Transient protection of clearances for reduced degradation with

hydraulic clearance optimization (HCO) active clearance control

Advanced Can Annular combustion system

All rotating blades replaceable without rotor de-stack or lift.

All blades removable w/o rotor lift

Vane 1 and blade 1 removable w/o cover lift (access through combustion chamber)

Blade 4 removable w/o cover lift
