Transformer Oils

SELTRA OIL

Low-viscosity naphthenic insulating oil produced from severely hydrotreated base stocks, offering excellent thermal and oxidation stability. It provides superior heat dissipation, high dielectric strength and fully meets IEC 60296 version 4.0 requirements as an uninhibited insulating oil. Designed for power transformers, switchgear and electrical systems requiring a premium mineral insulating and cooling medium, ensuring reliable thermal performance and long-term oxidation stability.

SELTRA OIL PLUS

Low-viscosity naphthenic insulating oil produced from severely hydrotreated base stocks, offering excellent thermal and oxidation stability. It provides high dielectric strength and superior heat dissipation, while its inhibited formulation (0.34–0.40% wt) ensures enhanced protection and extended transformer life. Designed for power transformers, switchgear and electrical systems requiring a premium mineral insulating and cooling medium with reinforced thermal and oxidation resistance.
