Middle East Query – Novinium Splices & Terminations

Middle East Query – 22 Questions.

In this final installment, I address questions 18 through 22 as they are all related to the splices and terminations utilized for sustained pressure rejuvenation or SPR. Here are the questions my dry friend posed …

18. If a cable were to fail after injection, can the customer use ordinary splices? Or should he use the “Novinium” specified splice? Can we use the traditional splices and terminations if a fault took place after treatment? In other words, do we have to use your splices and terminations on any treated cable all the time or that is only during treatments?

The probability of post-injection failure is quite low, but no rehabilitation approach is perfect. In the event that a post-injection failure does occur there are Novinium Rejuvenation Instructions (NRI-99) for “Cutting a treated cable.” Click here to see NRI-99. Step 9 of NRI-99 encourages the circuit owner to send a failure sample to Novinium so that we may learn from the experience. There are another set of instructions, NRI-93, which describe the best way to handle the failure sample. Click here to see the NRI-700 “Failure Sample Handling” instructions.

Once the failure is dispatched, it is time to repair the cable. Step 10 in NRI-99 encourages the use of Novinium® brand injection adaptors (IAs) to seal any remaining fluid in the cable. These IAs are inexpensive and provide a fluid-tight seal so that rejuvenation fluid does not come in contact with the new splice body and so that water can never enter the cable strands. At Novinium, we use only “ordinary” splices. In fact, Novinium injection technology is compatible with most splices. Click here to view two lists of Novinium Certified components. On that web page Table 1 provides a comprehensive list of dead-front terminations and Table 2 does the same for splices. If your splice of choice is not found in the table let me know and we can initiate the certification process.

Post-injection failures are rare with treated cables. Over two decades, the total failure rate is less than 1% with all technologies. The failure rate with Novinium technology is lower still.

Maximum reliability and minimum capital achieved by rehabbing all components.

19. Do the existing cable terminations need to be replaced? Will this introduce new splices?

Rehabilitation of a circuit is best accomplished if all the accessories are rehabilitated too. It makes little sense to extend the life of a cable by decades and leave 30-year-old terminations or splices in place. A chain is only as strong as its weakest link. For this reason, all terminations and splices are normally replaced to install Novinium injection adaptors and to ensure that proper craft work accompanies the rejuvenation of the cable. Twenty-plus-year-old-terminations and splices cannot be expected to last several more decades. If there is no slack in the cable, each cable lug is split off, so that no cable length is lost.

Removing and replacing terminations generally does not require the installation of a splice. Removing existing splices may require the installation of a second splice, because it may be impossible to remove the old splice without damaging the cable.

20. Are your splices and terminations available in the market or it is unique to Novinium?

Novinium only uses commercially available splices and terminations. However, we qualify each commercially available termination and splice before use to insure that it will allow Novinium to also install an injection adaptor and still remain inside of the conductive insert of the accessory. Once this is completed, we develop and publish an installation template for that accessory. Click Templates for a listing of certified components.

21. If we have to use your splices and termination all the time, do we need special training for our technicians and if yes can you provide such training and at what cost?

Novinium does not require special splices and terminations for future repairs. We only require that accessories we use will work properly with our injection adaptors—not all qualify. If you replace anything that Novinium installed, you can replace it with any standard accessory you may normally use. Any information you require to be confident of what action to take is provided in detail within the Novinium Rejuvenation Instructions or NRIs. Novinium sets the standard for craftsmanship and we will soon be sharing our expertise with the world. Watch for an announcement soon of an online craftsmanship training course at www.knovinium.com. Even if you don’t rejuvenate your cable, you should be learning from the world’s foremost reliability experts the best way to install components.

A proprietary Novinium lug-splitter removes the old lug without damaging the conductor. This preserves conductor length so that a splice does not need to be added even when there is no cable slack.

22. Did you type test your splices and terminations and are they certified to be used in such applications?

Yes, the accessory manufacturer has type tested all splices and terminations certified by Novinium. Further, Novinium tests each splice and termination to be certain that they will work with the Novinium injection adaptor. Once this testing is complete, Novinium publishes a template for that accessory at Templates. Many of the accessory manufactures have also reviewed the Novinium templates and procedures and have issued letters indicating that the Novinium technology is compatible with their components. See Novinium Certified Components and click on Hubbell, Cooper Power Systems, 3M, Richards Manufacturing, Prysmian, or Tyco/Raychem to view letters from the component manufacturers.
