APEX Elect Oil IH is a range of inhibited transformer oils that undergo rigorous refinement through hydro-cracking and hydro-treatment processes. These virgin insulating oils offer exceptional purity and stability. Manufactured from carefully selected modern feedstocks, they are highly suitable for various grades of power and distribution transformers, circuit breakers, oil-filled switches, and X-ray equipment.
APEX ELECT OIL IH INHIBITED OILS
APEX Elect Oil IH is a range of inhibited transformer oils that undergo rigorous refinement through hydro-cracking and hydro-treatment processes. These virgin insulating oils offer exceptional purity and stability. Manufactured from carefully selected modern feedstocks, they are highly suitable for various grades of power and distribution transformers, circuit breakers, oil-filled switches, and X-ray equipment.
Features & Benefits
- High dielectric strength.
- Low-viscosity oils offer excellent and fast heat transfer.
- Higher Flash point, resulting in Low evaporation losses and beer safety
- Remarkably low sludge and acidity formation, in both aging and oxidation tests, results in longer life of oil and equipment
- Compatible with transformer construction material.
- Very low sulfur and no DBDS.
- Low Pour point.
- Non-corrosive as tested by all present methods, DIN & ASTM tests & New IEC 62535 method.
Application
APEX Elect Oil IH Inhibited Transformer oils are highly suitable for all grades of
- Power Transformers, Distribution Transformers
