Transformer Oil
Greyhound Lubricants Transformer Oil is available in both inhibited (INH-T2) and uninhibited (UNH-T1) formulations, each blended with premium virgin base oils to deliver exceptional dielectric strength (73 kV), superior thermal conductivity, and long-term oxidation stability. Both grades are non-corrosive, PCB-free, and engineered to meet the performance demands of modern electrical systems.
For applications requiring extended service life and enhanced protection, INH-T2 is Eskom-tested and compliant, offering proven reliability in critical utility and industrial environments. UNH-T1 provides a clean, additive-free option ideal for legacy equipment, tender specifications, or specific operational requirements.
Suitable for power and distribution transformers, rectifiers, circuit breakers, and switchgear, both variants ensure dependable insulation and efficient cooling over a wide temperature range. Manufactured in ISO-certified facilities across Europe and globally, INH-T2 meets IEC 60296:2020 (Inhibited) standards, while UNH-T1 complies with IEC 60296:2020 (Uninhibited) — ensuring safe, clean, and compliant operation in all environments.
Applications: Power and distribution transformers; Rectifiers and circuit breakers; Switchgear and electrical insulation applications; Eskom Transformers (PCB-free)
