- 2 months
- 200pcs per month
THE SHAFT connects the turbine to the generator, turning at the same speed as the turbine.
Product Introduction
The shaft serves as the critical mechanical link between the turbine and the generator, rotating synchronously with the turbine to transmit mechanical energy for conversion into electrical power. This integral component operates under demanding conditions, requiring high precision, robust structural integrity, and reliable performance to maintain efficient energy transmission throughout the system.
