Novinium News: January 2017

When you buy something it starts to depreciate. A car will be less reliable next year than it is now. If one of our customers installs a new cable this year, it will be less reliable next year, and even less reliable the following year. We all recognize this phenomenon as the aging process. The black line in the graph below is the post-installation failure rate for new cables installed at a U.S. Southwestern utility between 1969 and 2005.* In general, and as expected, failures increase as the years since installation increase.

Salt River Project

The Salt River Project (SRP), a utility serving south Phoenix, Ariz., has a large population of aging feeder and URD cable. With numerous replacement projects, SRP saw its cost of line maintenance rising faster than the budget could handle. SRP decided to try Novinium® cable rejuvenation and has experienced a less than 1 percent failure rate on the treated cable.

Intermountain Rural Electric Association

The Intermountain Rural Electric Association (Intermountain REA) began to experience an increasing number of failures with cable laid in the in 1970s and ‘80s. By proactively rejuvenating entire neighborhoods before cables failed, the utility improved service levels to a 99.4 percent reliability rate and saved tens of millions of dollars.

London Hydro

London Hydro, Ontario, Canada

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.

Tacoma Power

Tacoma Power, Washington, U.S.A.

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.

Ergon Energy

Ergon Energy, Queensland, Australia

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.

Matanuska Electric Association (MEA)

MEA, Palmer, AK, U.S.A.

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.

Greenwood Utilities

Greenwood Utilities, Greenwood MS, U.S.A

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.
