ECHESA Series GE700PL

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.

Enhanced performance & availability

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.
