Wind Turbine lubricants are designed to protect the internal gearboxes of wind turbines - these machine components are constantly exposed to heavy loads and extreme pressures and require lubricants that can withstand these conditions. Furthermore, considering the limited access of these machine components, the lubricants employed within them should be able to function at a high level for long durations without oxidizing and failing. With excellent thermal stability and an extremely high load-carrying capacity, these lubricants are fit to operate in both new and older wind turbine gearboxes with great success.
ISO VG 320 oils have a midpoint kinematic viscosity of 320 mm2/s (or Cst, centistokes). This number is equivalent to an average of the minimum and maximum viscosities derived from AGMA testing. In the case of an AGMA 6 oil, these numbers are 288 mPa.S and 352 mPa.S respectively. Though these numbers do roughly equate to the same thing, it is best to consult with OEM specifications before employing any new oil in a system or machine.
