Experience has shown that electrical buses in bus ducts have failed due to:

  • Cracked insulators
  • Presence of moisture
  • Debris in bus duct enclosure
  • Dirt or dust build-up (additional threat in force cooled systems)
  • Iso Phase Bus conductor support insulator bolts loosen from vibration and thermal cycling
  • Aluminum laminate failure of conductor thermal expansion joint

In order to help prevent such occurrences, Electrical Builders has developed an Iso Phase Bus System Inspection and Specialized Cryogenic Cleaning Service.  During a plant scheduled or emergency outage, EBI will provide a crew to come to your facility to evaluate and report on your existing system.  Documentation can be provided via digital pictures with insulators, bushing and wall penetration identified via an assigned grid map.  EBI’s specialized cryogenic cleaning method has been proven superior to any hand cleaning method.  Don’t wait for problems to arise, contact us today to schedule your maintenance service.
