- resist aging processes during prolonged use;
- hydrolytic stability;
- anti-corrosion properties even when working in hostile environments (water, steam and condensate);
- water separation;
- low foaming;
- good filterability and high purity.

The first prototype of turbine oil appeared, probably, with the introduction of the first steam turbine. This was more than 90 years ago. At that time a steam turbine consisted of a steam turbine engine with rotating elements. The main function of this device was to make thermal energy into mechanical work. For connection of steam turbine with a drive mechanism was used power transmission mechanisms.
Over time, steam turbines slowly improved. Studies have found that to improve the performance of such mechanisms it is necessary to raise the temperature and the pressure of steam. This requires a higher quality of lubricants used in steam turbines. The very first turbine oils did not contain no additives, but the stricter conditions and requirements prompted the designers to make changes to the composition of lube oils. Additives to turbine oils have already been used for 50 years first introducing inhibitors of oxidation processes, as well as anti-corrosion agents. At the beginning of the XXI century other substances were added to the above mentioned- such as extreme pressure and anti-wear additives.
Have you ever wondered why there is a difference between transformer, industrial, cable, turbine and other types of oil? Wouldn’t it be easier just to call them petroleum or mineral oils? The fact is that each type of oil solves certain tasks and therefore has its own special structure. Special operating conditions of turbines define the requirements to turbine oils. Among them:
