Corrosion Protection Grease for Overhead Transmission Conductors
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.
Why Overhead Conductor Grease Is Used
Overhead conductors are exposed to changing environmental conditions, including humidity, rain, salt spray, and industrial pollutants. Without proper protection, corrosion may occur between aluminum strands, steel cores, and connection components.
Conductor grease helps to:
Reduce moisture penetration into conductor layers
Minimize galvanic corrosion between aluminum and steel components
Protect contact surfaces and conductor joints
Maintain conductor performance during long-term service
Typical Applications
OPSTECH overhead conductor greases are suitable for various power transmission and distribution applications, including:
ACSR (Aluminum Conductor Steel Reinforced)
HTLS high-temperature conductors
OPGW (Optical Ground Wire)
Compression joints
Dead-end clamps
Suspension fittings
Overhead transmission lines
Distribution networks
Protection in Harsh Operating Environments
Conductor grease is especially important for lines installed in areas with high humidity, coastal salt exposure, or industrial pollution.
By reducing corrosion factors, the grease helps maintain the physical condition of conductors and supporting components during extended outdoor operation.
Supporting Long-Term Line Performance
Proper use of conductor grease can reduce corrosion-related deterioration and help decrease maintenance requirements for transmission systems.
It provides additional protection for conductors throughout their expected service period.
Suitable for Standard Installation Processes
Overhead conductor grease can be applied during conductor manufacturing, installation, or maintenance operations.
The product is designed to work with common conductor assembly processes while maintaining stable protective performance.
Compliance with International Standards
OPSTECH overhead conductor greases are developed and tested according to relevant industry requirements, including:
IEC 61394
BS EN 50326
GB/T 36292-2018
