Problem:<br />
Over several years of service life, the seals between the ceramic insulator bushing <strong>and</strong> base would<br />
degrade. The failed seal would allow of SF6 gas to leak into the environment.<br />
Solution:<br />
Complete repair areas were roughened using a grinding machine <strong>and</strong> wire wheel attachment. Surface<br />
areas were then chemically cleaned using Cleaner Blend 300. A cardboard mold was manufactured to<br />
position the Wear Resistant Liquid Epoxy. A generous coating of release agent was applied to the<br />
cardboard mold. Release agent must be applied for easy part removal. Wear Resistant Liquid was mixed<br />
<strong>and</strong> transferred into simple caulking guns. Wear Resistant Liquid was injected into the mold <strong>and</strong> seal<br />
areas. Following a full cure (24 hours), the mold was easily removed.
