Power Cable Solutions
Case Studies

Over 100 million feet (30,500 KM) of cable have been rejuvenated using CableCURE® technology throughout the world.  The case studies listed illustrate how power cable owners have increased their cable reliability and significantly reduced repair and replacement expenses.

Sulphur Springs Valley Electric Cooperative

"We injected our first cables in 1996; approximately 7,600 feet. In that particular subdivision, our failure rate went from 1 fault every six weeks to 1 fault since that time. Not only does CableCURE treatment improve service, it improves customer relationships by avoiding trenching through existing landscaped easements. Pete Swiatek, our Maintenance Supervisor, has been impressed with the dramatic decrease in cable failures. He is also impressed with the close working relationships UtilX cultivates with their customers."

Mike Stringer, Construction Manager SSVEC

SSVEC (Sulphur Springs Valley Electric Cooperative), maximizes their capital budget while improving the reliability of system underground cables through the use of a proprietary rejuvenation technology. As is common with solid-dielectric polyethylene insulated cables (a.k.a. XLPE cable), SSVEC started experiencing an increase in failures due to water-trees. Faced with the imminent failure of hundreds of aging underground residential distribution cables, Mike turned to the only proven and cost-effective alternative to disruptive and costly cable replacement, CableCURE.  For a fraction of replacement costs SSVEC has treated approximately 350 spans of cable since 2000, totaling nearly 130,000 cable feet.  UtilX has been able to successfully treat 90% of the cables released to them, deferring replacement for 20 years or more while improving system performance.

 

Hydro-Sherbrooke Power

"[They] did an excellent job of adapting their technology to suit our needs. Since the CableCURE® enhancement work, we have experienced no failures on our feeder circuits."

Jean-Guy Thibodeau, division chief of Hydro-Sherbrooke

When a splice on faulty cable exploded in an underground vault, this Canadian utility needed to look at new, cost-effective ways to restore their buried cables. After researching alternatives, Hydro-Sherbrooke in Quebec chose to inject cables afflicted with water damage or splice failures with CableCURE silicone fluid, rather than to dig and replace. To complete the job efficiently, UtilX designed a specialized splice fitting allowing two different cable sections to be injected from one manhole.

Hancock-Wood Electric Cooperative

CableCURE/XL technology successfully repaired water damage and rejuvenated a 30-year-old submarine power cable for Hancock-Wood Electric Cooperative (HWEC) in North Baltimore, Ohio, U.S. UtilX designed patented flow-through splice to accommodate the maximum pressure of 400 psi needed for the project. The cost to install new splices and inject with CableCURE fluid was US$600,000. This compares favorably to the projected US$4 million to replace the damaged cable.

Enexis (formerly known as Essent Networks)

After injecting 158 KMs (1,554,000 cable feet) of cable with CableCURE, Essent experienced the following results:
  • After one year the insulation is even better as it was original when the cable was new.
  • In the pilot grid there was just one fault up to now (in six years).
  • Overall the faults have decreased enormously.  There is no difference with new generation XLPE cable anymore.
