Application of Overhead Conductor Greases

Corrosion Protection for Overhead Transmission Conductors

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.

OPSTECH overhead conductor greases are designed for different conductor systems, including ACSR, OPGW, HTLS, and related transmission line components.

Applications of Overhead Conductor Grease
ACSR Conductors

For ACSR (Aluminum Conductor Steel Reinforced), conductor grease helps protect the contact area between aluminum strands and steel cores.

It reduces moisture penetration and helps prevent galvanic corrosion between different metals, especially in humid, coastal, and industrial environments.

OPGW Conductors

OPGW (Optical Ground Wire) combines power transmission and communication functions. Grease protection helps protect metallic components from corrosion and supports long-term mechanical performance of the conductor system.

HTLS Conductors

HTLS (High Temperature Low Sag) conductors operate under higher temperature conditions than conventional conductors.

Suitable conductor grease helps maintain protection performance during temperature changes and long-term outdoor exposure.

Conductor Joints and Fittings

Overhead conductor grease is also used in:

Compression joints
Dead-end clamps
Suspension fittings
Other metal connection areas

It helps reduce corrosion at critical points and improves the durability of conductor assemblies.

Applications in Different Environments

Overhead conductor greases are commonly used in:

Coastal areas with salt exposure
Industrial areas with pollutants
High-humidity and heavy rainfall regions
Long-distance transmission networks

By providing a protective barrier, conductor grease helps maintain stable performance of overhead lines under challenging conditions.

Standards Compliance

OPSTECH overhead conductor greases are developed and tested according to relevant industry standards, including:

IEC 61394
BS EN 50326
GB/T 36292-2018
