ECHESA Series GE700PL

ECHESA Series GE700PL

Enhanced performance & availability

As part of our evolutionary development process, the 700kW ECHESA GE700PL gearbox inherits technologies, components, and subsystems previously deployed and proven through the reliable operation of over 5 000MW of Gamesa’s 700kW turbines.

The main features of the ECHESA GE700PL gearbox are:

  • modular 3-stage architecture with torque arms to the main frame
  • spur and helical gearing1 made from high grade alloy steels
  • structural castings made from high quality spheroidal graphite iron
  • lubrication by splash and electrical and mechanical pump injection

By incorporating technology enhancements, the ECHESA GE700PL gearbox, fitted to Gamesa’s G47 Class S wind turbine, promises to deliver nearly 75% more planet gear bearing load capacity compared to other makes. Additionally, there is a 90% nominal increase in ring gear fatigue life making it one of the most profi table and reliable solutions available in the market today.
