VVG GREASE
CORROSION PREVENTIVE GREASE FOR OVER HEAD LINE CONDUCTORS
Product Description
VVG GREASE is a corrosion preventing grease specifically designed for the protection of aluminum, aluminum alloy and steel reinforced overhead conductors. The unique combination of additives and base fluids delivers very good corrosion protection with long term stability resulting in enhanced protection throughout the service life of the conductor.
Unlike traditional waxes or soap greases commonly used in conductor
manufacture VVG GREASE utilizes a non-melting thickener system which results in
a drop point over 300°C and minimal oil separation. This ensures that the
grease structure is maintained throughout the operating temperature range and
oil migration to the outer surface of the conductor is significantly reduced,
helping to minimize corona effects.
Applications
VVG GREASE is designed for application at ambient temperatures and does not require heating prior to use. Application equipment should be thoroughly cleaned to remove residues of previous lubricants to avoid incompatibility issues.
Benefits
·
Exceptionally low oil
separation helps to minimize corona effects.
·
Operating temperature range
-20°C to + 250°C.
·
High thermal stability.
· Provides good
corrosion protection to steel, galvanized steel, aluminum and aluminum alloy conductor components.
Reduces abrasive wear and fretting on the conductor that can result due
to thermal expansion/contraction
and varying weather conditions
