Title: For Oil and SF6 Gas Leaks


1
For Oil and SF6 Gas Leaks
2
What is PowerPatch?
  • A specially formulated 3-part chemical system
    designed to adhere to metals, lead, porcelain and
    plastics to stop oil from leaking or to repair
    apparatus.

Leak Causes
  • Vibration
  • Welding failures
  • Storm damage
  • Vehicle damage
  • Poor gasket seating
  • Aging equipment
  • Bullets
  • Metal flex fatigue
  • Bad seam seals
  • Threaded joints
  • Transportation damage
  • Lightning

5
Benefits
  • Stops SF6 gas oil leaks in the field
  • Eliminates bagging and removal
  • Keeps transformers in service
  • Patch can be removed, if desired
  • Quick and cost effective
  • Extends life of hard-to-replace equipment
  • Can be a temporary fix during transportation

6
PowerPatch can fix
  • Cracks
  • Holes
  • Seams
  • Fins

7
Pipe Fittings
  • Easily repair leaking pipes in your system
    without replacing the pipes.

8
Oil Holding Tank Reservoirs
  • Repair leaking tanks, fittings, threads and pipes
    with PowerPatch. Avoid equipment replacement.

9
Potheads
  • Repair the factory sealed joint on top (or the
    lead splice joint on the bottom) of potheads.

10
Pad-Mounted Transformers
  • Corners are often damaged by fork lifts, parking
    lot accidents and during shipment.

11
Pole Mounted Transformers
  • PowerPatch allows you to fix the leaks in the
    field without taking the apparatus out of service.

Benefits
  • Will patch hard-to-reach areas
  • No torches or boiling pots of lead
  • Cures in 20-30 minutes
  • Impervious to oil, water, other contaminants
  • Will survive cable expansion, etc.

16
Pressure Testing
  • Extensive testing was done on PowerPatch to see
    how well it held up during environmental
    conditions.
  • PowerPatch can hold up to 15 pounds of constant
    pressure.

17
PowerPatch Technical Data
  • 43kv dielectric strength
  • Exceeds ASTM D 3808 aging adhesion tests for
    water, oil and heat cold cycling
  • Exceeds ASTM C 794 adhesion-in-peel elastomeric
    joint sealant test on lead, polyethylene,
    aluminum and steel
  • Meets impact test modification of ASTM G 14
  • Oil resistant formulation
