Overhead Conductor Greases

What is Overhead Conductor Greases

Overhead conductor grease is a protective compound applied to overhead conductors to reduce corrosion risks during long-term operation. It forms a protective barrier on conductor surfaces and internal contact areas, helping prevent moisture, oxygen, and corrosive substances from reaching aluminum strands, steel cores, and metal connection points.The grease is commonly used for ACSR, OPGW, HTLS, and other overhead conductor systems where reliable corrosion protection is required under outdoor conditions.

Application of Overhead Conductor Greases

Overhead conductor grease is used to protect transmission and distribution conductors from corrosion caused by moisture, salt spray, oxidation, and other environmental factors. During long-term outdoor operation, conductors are exposed to changing weather conditions. Proper grease application helps protect aluminum strands, steel cores, and metal contact areas, reducing corrosion risks and extending conductor service life.

History of Overhead Conductor Greases

Overhead conductor grease was developed to address corrosion problems that occur during long-term operation of power transmission lines. In outdoor environments, conductors are exposed to moisture, rain, salt spray, industrial pollution, and temperature changes. Over time, these factors can affect aluminum strands, steel cores, and conductor connection areas. The need for better corrosion protection led to the development and wider use of conductor greases.

ACSR Overhead Conductor Greases

Why ACSR Conductors Need Protective Grease Although ACSR conductors combine excellent electrical conductivity with high mechanical strength, their steel core remains vulnerable to corrosion when exposed to moisture over many years.

OPGW Overhead Conductor Greases

Why OPGW Conductors Need Protective Grease OPGW cables operate in challenging outdoor environments for decades. Continuous exposure to rain, humidity, coastal salt spray, UV radiation, and industrial pollutants may eventually allow moisture to reach internal metallic components, leading to corrosion and reduced cable reliability.

HTLS Overhead Conductor Greases

HTLS (High Temperature Low Sag) conductors are increasingly used in modern power transmission systems where higher current capacity is required without major changes to existing transmission corridors.
