ISO VG Grades:

Application:

• Oil-filled transformers, operating at 330 KV or less, where it acts as a non-conducting insulating and cooling medium

• Oil-immersed switch-gear

• Other electrical insulating applications

Performance Levels:

• IEC 60296-2003  

Features & Benefits:

• Excellent dielectric (insulating) properties, effectively prevent discharge in an electric field
• Low viscosity and low density lead to the oils having good cooling properties and good heat transfer characteristics at room temperature and below, and so ensure effective cooling of transformer core and coils
• Even at very low temperatures the oil viscosity remains low, and therefore allows the transformer to be started up under very cold conditions without problem
• Excellent oxidation stability characteristics are provided by the stable base oil together with the high-performance oxidation inhibitor system, and prevent the formation of acidic material and sludge in service, extending the life of the oil
• All four grades meet the requirements of IEC 60296:2003 for transformer oils

Packing:

• 20L, 25L, 208L
