CORR-EX
USE OF SUPERCORR A FOR MAINTENANCE OF
ELECTRICAL CONNECTIONS ON GAS TURBINES
IMPROVES PERFORMANCE BY REDUCING CORROSION
FRETTING
LP Gas Turbines are used throughout
the world by extraction industries and
manufacturing plants in remote and hostile
locations for essential power production.
Dusty and wet environments in deserts,
mines, grinding mills, pulp and paper mills
and on land or sea drilling rigs for gas and
oil production. Turbines powering aircraft
services while stationary connect and
disconnect many times a day in extreme
conditions.
These applications and locations test
connector sealing continuously allowing
dust or water to penetrate.
This with the flexing of the connecting
cables allows sufficient movement between
the metal surfaces of the connecting
pins to produce fretting corrosion which
reduces, interrupts or produces failures in
supply. Regular maintenance of electrical
connectors is essential to be certain of
uninterrupted supply.
SuperCORR A is an aerosol lubricant
containing corrosion preventive
compounds, and, as is the case with all
lubricants, they can be worn off over time.
A manufacturer of connectors tested
SuperCORR A to see what the "life" of the
lubricant was in a "rub test".
The typical test is 20,000 cycles, i.e. unplug,
plug in is one cycle.
The test results demonstrated that after
20,000 cycles there were no failures. It
was decided to take it one more step and
run the same tests for 200,000 cycles. The
results again showed no indications of
galling or scoring on the connectors at
all. The connector looked and tested as
good as new. This test was run under clean
conditions in a laboratory but demonstrates
the effectiveness of the protective lubricant
in SuperCORR A.
As it meets Mil-DLT-87177B specifications
it is used by the U.S. Air Force to protect
the intricate workings of the F-16 and F-15
fighter jets and by the U.S. Navy on the P 3
Orion electronic surveillance aircraft. Savings
for the U.S. government is estimated at $50
million per year.
Commercial Aviation aircraft manufacturers
recommend it for avionics and electrical
switches and connectors and close
mechanical application, especially where
flights are in salt fog or high humidity.
Containing extremely long-lasting,
proprietary anti-corrosive inhibitors
SuperCORR A provides a superior lubrication
coefficient and protects components
against moisture, wear, general and fretting
corrosion, surface static electricity, corona,
and other electro migration problems.
The super thin non-flammable lubricant film
is only 7 microns (0.0007 inch) thick and is
formulated without sulphates, chlorides or
halogens to meet the RoHS directive. It is
unexcelled in preventing deterioration and
contamination on all surfaces of electronic
equipment. Very fast drying environmentally
acceptable solvents are used as carriers
and propellants which will not affect most
plastics, substrates, metals or other materials
used in connector manufacture.
The aerosols are supplied with probes which
allow access to pins and connector tubes
where the low surface tension repels water,
dirt dust and metal particles from blind
holes and surfaces to produce thoroughly
clean holes and surfaces before a second
application applies the lubricant film.
Reconnection to the supply with cleaned
sections of the connector ensures reliable
operation even in the most testing of
environments. This easy maintenance from
one can of SuperCORR A allows this essential
task to be carried out in any conditions
quickly, easily and securely.
