CASE STUDY – N345kV HPFF FEEDER SYSTEM
PROBLEM:
A northeastern utility was experiencing an unacceptable amount of dielectric fluid leaks on their underground 345kV electrical feeder system. System reliability was being impacted and the state’s environmental protection agency was threatening to impose an administrative consent order forcing them to replace the aging lines.
CHALLENGE:
The system could not be taken out of service. Temporary barrel repairs and clamps were installed throughout the system and the entire system was coated with asbestos containing mastic.
SOLUTION:
Carbon Fiber Engineered Solutions installed our engineered system while the electrical feeders remained fully energized. Our solution fully encapsulated the existing electrical feeders, previous barrel repairs and asbestos containing mastic coating. Our composite carbon fiber solution is rated for 1,000 psi and serves as a secondary pressure boundary for the existing feeders. Carbon Fiber Engineered Solutions stopped the leaks, eliminated costly cleanup efforts, eliminated environmental reporting, restored system reliability and added 30+ years of maintenance free life.
