Si-COAT RTV Silicone High Voltage Insulator Coating
A Proven Success
“Our plant supplies the equivalent amount of electricity that a city the
size of Seattle uses, and it is a complex task to bring a reactor back
on line after an unexpected trip. Our plant is a very important power
supplier in our region, and is directly connected to the US Department
of Energy 500kV grid.
…because my problem was big, the pressure was on me to do something
to prevent future flashovers. The Nuclear Regulatory Commission monitors
our performance, and saw these reactor trips as detrimental challenges to
our reactor shut down systems. A permanent solution was required. The
method of utilizing a coating was selected. The story about how Si-COAT
570 HVIC rose above its competitors during testing is history. We applied
it at the next opportunity and have not had a flashover since 1992.”
ENERGY NORTHWEST, Columbia Nuclear Generating Station, Washington, USA
“Hydro One Networks Inc. installed Si-COAT RTV Silicone High Voltage
Insulator Coating (HVIC) at its Hamilton Beach Transfer Station
(TS) in January 1994 to all bushings. Prior to 1994 the station was
experiencing flashovers many times a year, which required power
washing of the bushings multiple times annually.
Since installation of the Si-COAT HVIC at Hamilton Beach, there has
not been a single flashover on the coated bushings, no re-coating has
been conducted since then. In the interest of precaution by Hydro One,
the coated insulators were power washed once annually only. Feedback
from the manufacturer, however, says that power washing of the
coating is not necessary.
The Si-COAT HVIC product has given flawless performance.”
HYDRO ONE NETWORKS INC., Ontario, Canada
“Just a short note to let you know that the Basslink outage was very
successful. I was particularly impressed with the Si-COAT work that
was completed on the DC insulators. The coating is very impressive,
the product seems to be very effective.”
NATIONAL GRID AUSTRALIA PTY LTD., Melbourne, Australia
