As an alternative to ongoing cable replacement, London Hydro asked Novinium to conduct a pilot cable injection project in a large subdivision. Since then, Novinium has gone on to inject more than 174,465 meters of cable for London Hydro and cable failures have declined by 58 percent.
Some 4,800 feet of submarine cable from Tacoma Power, feeding 14 customers on tiny Ketron Island, was nearing the end of its design life. The utility decided to rejuvenate the underwater line before a fault occurred and has not experienced any faults in the now-guaranteed, rejuvenated cable.
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.
The Glendale Subdivision had experienced numerous faults—as many as five or six a year dating as far back as 1984. Greenwood Utilities hired Novinium to rehabilitate the utility’s vaults and treat the cable line in the area. After the project was finished, the subdivision experienced no faults.
Estimated costs for the St. Charles Municipal Electric Utility cable replacement needs came in at about $6.6 million. St. Charles chose a solution comprised of 77 percent Novinium® cable rejuvenation and 28 percent cable replacement, saving $4.3 million, or 66 percent of the original project estimate.
