from American Polywater Corp for Transformer Leak Repair Service
Use the PowerPatch® System's putty stick to block oil and SF6 leaks.Then make a permanent patch with the fast cure, 2-part paste overcoat.Ensure optimal mix and performance with pre-measured packaging.
Seals punctures or cracks in hard to reach areas.Fixes leaks fast.At 70°F, the putty and sealant harden in about 10 minutes.Repairs made at temperatures as low as 40°F, have a somewhat slower cure.The finished patch is resistant to transformer oil and sulfur hexaflouride gas (SF6), and has held oil pressures in excess of 100 psi.
Preparation is important, and the kit approach provides everything needed to do the job, although in instances of excessive oil leakage or dirt accumulation, separate scrubbing rags such as Grime-Away™ Cleaning Wipes are helpful.
