PowerPatch® System

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.

It is non-conductive and has a dielectric strength of 43KV (ASTM D149).

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.*Slower cure version available for larger leaks and repair areas.

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.   Read detailed application instructions before using.

TESTIMONIAL:   "This product was used on a pad-mounted switchgear that had developed a rust hole on a corner, allowing possible access to energized parts.   Product was easy to apply and went over rusted area quite well.   It cured well and has adhered to rusted surface, allowing us to delay replacing a $40,000.00 unit that had this one defect."




PowerPatch® Kit

The PowerPatch® Sealant is provided in a kit containing the preparation and patching materials necessary to repair oil and SF6 gas leaks in transformers, lead-sheathed cables, potheads, and other oil-filled, electrical equipment.   Kits can be customized to end-user requirements.
