Upgrade
Upgrade and Efficiency improvement to be realized using the state-of-the-art VP-X component technologies.
Note: Power-generator business was transferred to Mitsubishi Generator Co., Ltd on April 1, 2024. Click here for details.
Uprating Technology
Advanced high performance insulation
The latest main insulation for stator winding is improved with lower thermal resistance and more efficient heat-transferring characteristics. On the indirectly cooling type generator, stator winding cooling performance to be improved using the latest main insulation.
Key Technology
- Lower thermal resistance in main insulation
- Improvement of heat－transferring characteristics in main insulation
Improved cooling ventilation
The ventilation resistance on rotor cooling path to be reduced by the optimization of duct entrance shape. Cooling performance for rotor to be improved by reducing ventilation resistance and increasing ventilation flow rate of the cooling gas.
Key Technology
- Optimization of duct shape at entrance part
Efficiency Improvement Technology
High performance fan
Mechanical loss to be reduced by fan shape optimization and installation of guide plate.
Key Technology
- Optimization of fan shape
- Installation of guide plate
Non-magnetic partition plate
Stray loss to be reduced using the Nonmagnetic partition plate.
Key Technology
- Application of nonmagnetic material for partition plate
Low loss bearing
Mechanical loss to be reduced using the direct lubrication 2 pad journal bearings.
Key Technology
- Application of direct lubrication 2pad journal bearings
Upgrade Opportunity
Upgrade would be completed within a original regular inspection schedule or within rotor/stator rewinding schedule.
