ECHESA Series GE850PL

ECHESA Series GE850PL

Reliability & excellent performance

The 850kW ECHESA GE850PL gearbox, that has been proven through the reliable operation of over 5000MW of Gamesa’s G5X turbines, and still continues to create customer value which each delivered unit by means of the most robust and cost-efficient bearing arrangement.

The main features of the ECHESA GE850PL 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

The ECHESA GE850PL gearbox, fitted nowadays to Gamesa’s G52 Class IA and G58 Classes IIA/IIB wind turbines, assures optimum performance for low, medium and high winds, making it one of the most reliable and profitable solutions available in the market today.
