Middle East Query – 22 Questions.

In this installment I address question 6.

6.   Does injection apply only at utilities or can it be applied at industrial plants too?

Novinium injects medium voltage cables for utility distribution systems, utility power plants (non-nuclear and nuclear), and many industrial customers.  Check out just a few industrial applications in the collage below.  For even more pictures and more applications check out our happy faces injecting cables all over the world and at many different venues on the Novinium Facebook page.  As revealed in my post to your question 1, at Middle East Query - Treatable Cables there are a wide range of cable types and sizes that can be addressed with a tailored solution™ from Novinium.

NRI Copyrights

Dear Omnipresent Amphibian,

I am looking at the Novinium web site and the "Novinium Rejuvenation Instructions" (NRIs) say they cannot be duplicated without prior approval.

My power distribution firm is a user of Novinium technology and I would like to request approval for my firm to copy and distribute information from your web site that may aid us in training and preparing work practices for our crews.

Can you find it in your cold heart to grant me permission?

Copyrights or Copywrongs

Dear Copy-

Your heart is always the same temperature – how boring is that?  For a good part of the day I perch underneath a lamp that warms me to whatever temperature I desire.  If I get too warm I take a quick dip.  I am in control, while you suffer from a mono-temperature existence.  I feel for your temperature and your copyright plight.

Novinium is pleased to grant approval to our customers to copy and distribute information from the Novinium web site that may aid them in training and preparing work practices for their field crews.  Just write to your sales professional to make a formal request and they will respond with the required permission in short order.  Please be aware that the NRIs are living documents, which are continuously updated as new technologies and techniques are improved and perfected.  The last edit date of each NRI is provided on the NRI web page.  The NRI end-user should check the date of printed copies against this last edit date to assure that the most up-to-date instructions are being utilized.

Novinium field teams have access to the latest NRIs electronically through our state-of-the art NITS/FDE software.  NITS stands for “Novinium Injection Tracking System” and FDE is our “Field Date Entry” module.  The FDE module provides electronic access to the system even when our teams are not directly connected to the internet.

Warmer than you think,

Middle East Query – 22 Questions

In this installment I address questions 4 and 5.

4.   How much time does it take to inject a certain length of cable?  What is the maximum cable length that can be injected?

The longest cable to date that Novinium has injected was 4,400 meters.  This was a 53 mm² compact strand submarine cable out to an island.  Check out the aerial photograph.  The cable path was at a maximum depth of 500 meters.  We know how to go much longer.

Injection times are dependent on:

a.   Insulation material—XLPE injects faster than EPR

b.   Strand compaction—round strands faster than compact or compressed strands

c.    Cable size—larger cables inject faster than smaller ones, because there is more space between the strands

d.   In general, a 100 meter piece of cable injection requires less than 30 minutes.

If you have a specific long cable in mind, give me the particulars and I can show you how we calculate how long it will take.  There is also a June 27, 2007 paper, “Advances in Chemical Rejuvenation of Submarine Cables” that explains the basics.

Novinium provides the technology to identify the number and location of buried splices.  The number and approximate location of splices can be determined in less than 15 minutes with a time domain reflectometer or TDR.  Buried splices can be accurately located in 1-2 hours depending on access to the cable path and the number of other cables in the same area with a radio frequency locator or RF locator.  We describe how this is accomplished in Novinium Rejuvenation Instruction 12 (NRI12).

A TDR sends an electronic pulse down the cable.  Changes in impedance create reflections that are displayed on the instrument as wave forms.  It is important to use an impedance streamliner (IS) to minimize the reflections at the connection between the TDR and the cable.  The photograph nearby shows a Novinium proprietary IS and a high resolution TDR.  The inset shows a TDR in use by a master craftsman.

The illustration below shows how a splice is pinpointed with a RF locator.  A signal is impressed between the conductor and the concentric neutral.  The two signals are 180° out of phase, so they tend to cancel each other out.  I say they tend to cancel, because the canceling is not perfect and some signal leaks through allowing the master craftsman to follow the cable path.  The signal strength typically skyrockets when the craftsman nears a splice, because the concentricity of the neutral is generally disturbed at the spice.

For now, Ma’a salama (مع السلامة/Good bye)

In this installment I address question 11.

11.   How many years will the curing extend the life of the cable?

Patented Novinium Ultrinium™732/733 fluids will extend medium voltage cable life more than 40 years when applied with Novinium’s patented SPR or sustained pressure rejuvenation process.  If that is too much or not enough, talk to us, we can tailor the performance to your needs.
