Transformer Leak Repair System for Gas and Oil Insulated Transformers

Polywater® PowerPatch® Transformer Leak Repair permanently repairs oil and gas leaks commonly found in:

  • Bushing & portal gaskets
  • Bolt & nut leaks
  • Welding defects
  • Valve & meter connections

The fast, durable repair of oil and gas leaks with PowerPatch® is an economical and effective means to protect essential electrical grid assets. The repair of leaks in the field with PowerPatch® reduces risks to the environment and personnel, and increases the overall performance of the electrical grid.

Leak repair with PowerPatch® reduces the length and frequency of power disruptions to ensure the maximum efficiency of the grid. PowerPatch® is an easy and fast way to repair leaks in transformers by following a step-by-step process. PowerPatch® is successfully applied in numerous installations around the globe, in extreme climates and difficult spots

Product/Package Notes:

  1. PowerPatch® Transformer Leak Repair comes in several field-friendly forms.
  2. PowerPatch® EPCT comes in a side-by-side cartridge (shown above) that mixes the two parts as they are applied. A plunger tool is required for application.
  3. PowerPatch® EP is a thicker paste that comes in premeasured Part A and B cups. The two parts are hand mixed before application.
  4. PowerPatch® EPSC is a slower-curing version recommended for large repairs where more pot life is needed.
  5. The PowerPatch® Sealant is provided in kits with the preparation and patching materials necessary for a good repair. See details in the product table below.
  • Fast Repair: Stops active leaks without shutting down equipment.
  • Convenient: Seals active leaks in minutes. Also eliminates “bagging” of transformers during transit.
  • Resilient: Seal is UV and weather resistant for long-term durability
  • High Adhesion: Adheres to a variety of substrate materials for fast and effective leak repair of power transformers, gas insulated switchgear, and other electrical assets.
  • Chemically Inert: Will not affect oils, solid insulation or other equipment

Specifications and Applications:

Electrical Reliability: Moisture can damage transformers. Sealing leaks quickly as they occur is the key to keeping moisture from entering transformers and causing premature or catastrophic failure.

Chemical Resistance: Sealant chemically resists dielectric fluids, SF6 gas, ultraviolet light, water, and oil.

Leak Sealing Performance: Sealant shows good adhesion to numerous metals, ceramics, and rubbers; and no leakage under high pressure (up to 100 PSI) with both air and polybutene oil.

Electrical Testing: Sealant is non-conductive. Dielectric strength is 43 kV using ASTM D149, Method A. Platen samples are cast and fully cured.
