The Polywater PowerPatch Transformer Leak Repair System is an economical and highly effective solution for sealing active transformer leaks in the field, often without the need for equipment shutdown. This versatile seal system can repair small pinholes, cracks, bolts, gaskets, and larger areas on transformers, GIS systems, and PILC cables. With its strong material adhesion and fast cure time, PowerPatch creates a durable, moisture-resistant seal that protects essential grid assets from accelerated aging, unplanned outages, and environmental risks, such as oil or SF6 gas leaks.
Key Features:
- In-Field Repair: Fixes active leaks in transformers and PILC cables without requiring service shutdown, reducing operational disruptions.
- Strong Moisture Seal: Forms a moisture-resistant barrier that helps protect transformers from premature aging and damage.
- High-Pressure Resistance: Can withstand high oil pressure, up to 100 psi (0.69 MPa), and is ideal for sealing the largest oil-filled transformers and GIS systems.
- Superior Material Adhesion: Bonds to steel, copper, porcelain, lead, and other common electrical substrates, ensuring a long-lasting repair.
- Dielectric Compatibility: Reduces partial discharge of oil and solid insulation, maintaining equipment integrity and performance.
- Durable and Reliable: Withstands temperatures from -40°F to 300°F (-40°C to 150°C) and retains strength after exposure to dielectric fluids, oils, and gases.
- ASTM Tested: Meets ASTM D3455 for oil quality, ASTM D1002 for adhesive strength, and ASTM G14 for impact resistance, ensuring high performance in demanding environments.
- Versatile Application: Usable on vertical and inverted surfaces without sagging and prevents galvanic corrosion.
- Non-Conductive: Tested with dielectric strength of 469 Volts/Mil per ASTM D149.
Polywater PowerPatch is the ultimate leak repair solution for protecting transformers, minimizing unplanned outages, and preventing environmental hazards. Available in convenient kits, this easy-to-use system is designed for field applications and ensures reliable repairs to extend the life of critical equipment.
