An Overview of the ABB UFES active arc flash reduction solution


Our November speaker will review various types of cable ties and their applications with respect to extreme conditions, The speaker will review application considerations including  life expectancy, and economic issues.  

When I was a young salesperson, I sold a few dozen cast resin power transformers to a client who used them to replace existing liquid filled substation transformers.  The cast resin transformers were a perfect fit,  efficient, eliminated the risk of fluid leaks, offered 50% overload capacity, and were quiet as could be.  The customer was happy; until one night when one of the cast resin transformers experienced a fault, taking the substation and the factory off line.    A cable tie supporting the temperature monitor control wiring became brittle and broke, allowing the wiring it was supporting to fall against the transformer coil, where it came in contact with the HV tap hardware. Boom!   Finn received an unpleasant 2:00 AM phone call.   Fortunately, no one was injured, but they could have been, for the standard NEMA 1 substation transformer enclosure is not designed to contain an arc flash.  The transformer manufacturer used general purpose nylon cable ties rather than a tie specifically designed for high temperature applications.  Engineers apply significant resources into designing reliable systems, specifying the right circuit breakers, fuses, and distribution equipment; yet, an improperly applied small, seemingly simple item, like a cable tie,  can  lead to  system failure, financial loss, injury, and worse.  Join us for a discussion on specifying the right cable tie for your crital applications.
