FAQs

What is cable rejuvenation?

Cable rejuvenation is the injection of a healing and upgrading fluid into the strands of medium-voltage power cable to repair and extend the life of your aging cable.

The rejuvenation fluid migrates into the conductor shield and the insulation, modifying the chemistry of the insulation and extending cable life.

The dielectric strength of your cable increases immediately and will exceed 400 volts/mil within seven days of Sustained Pressure Rejuvenation.

 

Our cable is too far gone. It’s that old, unjacketed, 40-year-old cable. You can’t do anything with that, can you?

The unjacketed 1970s vintage cable has been the largest population of cable that we have injected.

 

How much cable rejuvenation has been performed?

Over the last 27 years, circuit owners have rejuvenated more than 131 million feet of medium-voltage power cables. Of all these cables, less than 1 percent have failed in service.

 

What cable rejuvenation processes does Novinium offer?

Novinium offers sustained pressure rejuvenation (SPR) with a 40-year warranty (splice replacement), in addition to improved unsustained pressure rejuvenation (iUPR), which has a 20-year warranty (splice flow-through). Our hybrid injection process, which combines SPR and iUPR (depending on each segment), provides the maximum benefit and the greatest percentage of injected segments, saving replacement costs.

 

How long does it take to inject a cable segment?

On a typical residential, 300-foot 1/0 segment, injection takes less than two hours, including the switching, craft work, and injection. On looped systems, or where primary jumpers can be utilized, there is no outage required.

Can cable rejuvenation be capitalized?

Both FERC and RUS have approved cable rejuvenation for capitalization.

 

What is the cost of cable rejuvenation?

Cable injection is typically less than one-half the cost of replacement, and the economics almost always favor rejuvenation over replacement.

 

What is the business case for cable rejuvenation?

  • Increased system reliability
  • Lower costs
  • Less time
  • Less manpower
  • Less equipment
  • Minimum disruption to your customer
  • Capital vs. O&M budget

My neutrals are bad. How can you help?

This neutral-corrosion paper describes how more than 120 million feet have been injected in the last 25 years and less than 4 percent have been turned down because of corrosion issues.
