Overhead power conductors are critical assets for power grid infrastructure. Exposed outdoors year‑round, they suffer salt mist, industrial pollutants, moisture and drastic temperature fluctuations. Corrosion will trigger wire strand abrasion, premature aging and potential power‑supply failures.

        OFILL OFL‑series OVERHEAD CONDUCTOR GREASE is cold‑applied anti‑corrosion grease specially engineered for overhead bare conductors. Adopting special thickener system compounded with anti‑rust and antioxidant additives via dedicated manufacturing process, it delivers reliable anti‑corrosion protection for steel, galvanized steel, aluminum‑clad steel, aluminum and aluminum‑alloy conductor assemblies.

This product meets GB/T 36292‑2018, BS EN50326‑2002 and IEC 61394‑2011 standards. It has obtained third‑party physical‑chemical inspection and RoHS environmental compliance certification.

Core Performance Advantages

✅ Outstanding Rust & Corrosion ResistanceProtects overhead conductors against damages from harsh outdoor atmospheric conditions.

✅ Excellent Oxidation & Aging ResistanceEnsures long‑term service life of grease inside power conductors during continuous operation.

✅ Superior Water‑Blocking & Anti‑Emulsifying PropertyEffectively prevents conductor corrosion under humid and water‑exposed service conditions.

✅ Custom‑Wide‑Range Temperature CompatibilityCustom‑formulated grades cover operating temperature from ‑50℃ up to 280℃, maintaining stable colloidal property and minimum oil separation across full working temperature range.

OFILL OVERHEAD CONDUCTOR GREASE Main Grades

🔹 OFL20A (OFL20A120)Economical cold‑applied overhead conductor grease. Working temperature: ‑20℃ ~ 120℃. Low oil‑migration formulation, stable structure over full operating range. Ideal for general overhead transmission lines and bare metal conductors.

🔹 OFL40A (OFL40A240)Non‑melting thickener formulation. Remains flexible at ‑40℃, drop point＞300℃. Ultra‑low oil separation under service temperature. Excellent anti‑corrosion performance for coastal, high‑humidity and heavy industrial‑polluted regions. Working temperature: ‑40℃ ~ 240℃.

🔹 OFL50A (OFL50A280)Designed for extremely demanding complex environments such as coastal zones and heavily‑polluted industrial areas. Retains good flexibility without cracking or peeling at ‑50℃, drop point＞300℃, achieves minimal oil separation up to 240℃. Reduces fretting wear caused by conductor thermal expansion and contraction. Working temperature: ‑50℃ ~ 280℃.

Typical Applications

For anti‑corrosion and lubrication protection of outdoor bare overhead power conductors. Especially suitable for projects requiring strict colloidal stability and long‑lasting anti‑corrosion performance.

⚠️ Important Notes

• This is cold‑applied OVERHEAD CONDUCTOR GREASE. Select proper grade according to local climate and conductor design temperature.
• Do not mix with other types of greases.
• Store in cool, ventilated warehouse, keep away from open flame and high‑heat sources. Please refer to the OFL20A120 MSDS for full safety operation instructions.
