Facing difficult weather challenges and unusual soil conditions, Novinium® restored a cable line in Queensland, Australia that had been abandoned for five years. Novinium tailored their Cablecure® 732 fluid for warm tropical and desert soils, achieving renewed reliability on the cable.
Homer Electric Association (HEA) oversees a large service area with miles of decades-old electric cable in multiple areas. To stem recurring outages, the utility tried out the Novinium cable injection process and now uses cable rejuvenation regularly.
The Littleton Electric Light Department has been providing reliable power to the towns of Littleton and Boxborough, Mass. for over a century. By using the new Novinium cable rejuvenation process, Littleton Electric avoided the cost of replacing an important set of previously injected underground power lines.
Matanuska Electric Association (MEA) found that even subdivisions with well-laid cable were experiencing increasing faults with the stress of multiple freezes each year, so the utility decided to try cable injection to restore reliable service. Now, the Novinium-trained MEA staff can do the work so efficiently that MEA plans to continue using cable injection year-round.
Failure Causes I Q: I wonder if you have any information I could use to help address a concern I have heard in my company. That concern is that a 30 to 40 year old cable may have accumulated degradation due to many types of aging factors. Cable injection may not substantially address these factors…
Q: The blog post titled Neutral Corrosion — How Much Is Too Much? includes a waveform from a TDR (time domain reflectometer, often called a radar) that is used to pinpoint bad sections of cable neutral. The TDR is also used to pinpoint splice locations on the cable. How does the TDR determine the neutral corrosion and splices on the cable? And how is the waveform read to tell them apart and to pinpoint their locations?
When it comes to rehabilitating aging underground power cables there are basically three tool choices: A good choice, a better choice, and the best choice. The only bad choice is to do nothing at all. Integrated Rehabilitation uses all of the available tools and applies them in the order: best, better, good.
