Product Description

Gulf Transcrest U is high performance uninhibited electrical insulating oil specially designed for use in transformers, switchgears and other electrical equipment. This oil is formulated with high quality severely hydroprocessed naphthenic base oils and do not contain antioxidant or metal passivating additives. It possess good dielectric properties and heat transfer characteristics due to the low viscosity and is free from detrimental traces of water, dust and fibrous material to provide reliable operation with reduced down-time and improved service life. Gulf Transcrest U exceeds the performance requirements of major transformer and switchgear specifications.

Features & Benefits:

  • High dielectric strength ensures excellent insulation and quenching of electric arc between switchgear contacts when opening the switch.
  • Low power-loss contributes to overall efficiency.
  • Free from traces of water, dust and fibrous material and hence has no detrimental effects on the electric properties of the oil leading to maximizing oil and equipment life.
  • Low viscosity and high interfacial tension ensures good wetability of oil and removal of air gaps to insulate windings and dissipate heat.
  • Effective long term protection from rust and corrosion to critical system components.


  • Insulating and cooling oil for electrical transformers, switchgears, circuit breakers, capacitors and automotive ignition coils.
  • Used where inhibited insulating oils meeting IEC 60296: Uninhibited type (U) are required.
