SPEC OIL TDS TURBINE OILS 32, 46, 68, 100





SPEC OIL TURBINE OILS 32; 46; 68; 100

DESCRIPTION
Turbine Oils is a range of premium quality base oil blends, double inhibited and formulated to full the lubrication requirements of steam turbines. These oils exhibit outstanding demulsibility and air release properties as well as minimized sludge formulation and do not foam or froth in use.

APPLICATION
  • Turbine Lubrication.
  • Precision Ring-Oiled bearings.
  • High-Speed gears requiring an oil of turbine quality.
  • Enclosed crank-case steam engines.
  • Crankcase lubrication of reciprocation / Rotary Type Air Compressors.

PERFORMANCE LEVELS
Turbine oils meet and exceed the requirements of the main turbine manufacturers.

SPEC OIL TDS TRANSFORMER OIL RG





SPEC OIL TRANSFORMER OIL RG

DESCRIPTION
Transformer oils or insulating oils are usually a highly-refined mineral oil that is stable at high temperatures and has excellent electrical insulating properties. The functions of these oils are to insulate, supress corona and arcing as well as to serve as a coolant.

APPLICATION
Transformer oil is used in:
§       oil-filled transformers,
      some types of high voltage capacitors,
§       fluorescent lamp ballasts of high voltage switches
§       and circuit breakers.

BENEFITS
§  Transformer oils helps cool the transformer.  
§  Transformer oils must remain stable at high temperatures for an extended period because it also provides part of the electrical insulation between internal live parts.
§  The oil-filled tank may have external radiators through which the oil circulates by natural convection to improve cooling of large power transformers.
