Our Technology

Novinium helps electric utilities address their aging underground infrastructure by restoring aged cables to like new or better condition.

Soon after underground cables are installed, the wet environment causes water trees to grow. The growth of water trees reduces the dielectric strength of the insulation. The reduction of this dielectric strength can cause electrical/catastrophic failure of the cable. 

Cable injection introduces silicone fluid into power cable strands. The fluid migrates into the conductor shield & insulation. This process improves the chemistry of the insulation and the physics of the cable to extend the reliable life of the circuit.

Novinium offers utilities the opportunity to invest capital in their underground distribution system, reduce O&M annual expenditures, increase reliability of their underground grid and reduce emissions by rejuvenating aged underground cables. 


Novinium’s patented cable rejuvenation methods can be used independently or in combination to address any technical challenge including URD, feeder, submarine cable, extreme temperatures, blocked splices, radial segments, and neutral corrosion.

The silicone fluid, invented by Dow Corning, continues to be improved each year as additional Novinium research is completed.  Novinium partners with Dow Chemical (Dow Corning) to provide fluid manufacturing and technical support.

Novinium’s patented cable rejuvenation fluids are specially formulated to ensure optimal performance in tropical soils, subzero temperatures, and everything in between.

Cable Rejuvenation Changes the Course of History at NV Energy: An In-depth Case Study

For the past 22 years, cable rejuvenation has played a key role in NV Energy’s (NVE) delivery of reliable electric power to its customer base of over 1.3 million homes and businesses in the United States’ desert southwest. Since the beginning of the program in 1998, more than 12 million conductor feet of their underground residential distribution (URD) system have been successfully rejuvenated by silicone injection. This paper will explore the evolution of NVE’s reliability program from trial phase to present and the metrics used to gauge the success of silicone injection. Further, the application of predictive modeling as a tool for forecasting future outages and estimating outages saved will be defined.

What the heck is Cable Rejuvenation? 

If only we could do for humans what we do for underground residential distribution (URD) cables. Imagine that as you approached the end of your life, you could drink a magic elixir and within a week you could perform at your peak in every way for another 40 years. That is precisely what Novinium® brand Cablecure® rejuvenation fluid does for URD cables. Your power utility has another option, it can replace the aging URD cable with new cable. The new cable will perform reliably, but installing it will tear up streets and landscaping, take a lot longer, squander scarce world resources, and cost 2 to 5-times more, which must ultimately be reflected in your electric rates. Cablecure rejuvenation is a safer, faster, and better alternative.

Secondary Service Injection

Secondary service cables form the last link in the power grid by interconnecting the distribution transformer to the end user’s service meter. For many utilities with underground services, failures on this class of cable account for over half of their total cable-failure count and are on the rise. Utilities would traditionally be faced with a decision to continue to make ad-hoc repairs or create a replacement program. This paper introduces silicone-gel injection as a third option for utilities to consider. The injection of silicone gel purges water from the conductor and forms a physical barrier that protects against water intrusion and corrosion. Silicone-gel injection is a non-invasive solution that causes minimal disruption to neighborhood homes and businesses.

Neutral Corrosion 

This paper reviews six neutral corrosion issues and provides data to shed some light on the overall significance of the phenomenon. The paper draws upon IEEE 1617 and encompasses and expands upon the 1617 scope. This paper defines the purposes of the neutral, the consequences of excessive corrosion, the causes and chemical dynamics of neutral corrosion, dimensions the severity of the issue in North America, describes how to detect neutral corrosion, and provides options to address neutral corrosion once discovered. The paper also suggests areas for future work to provide guidance to circuit owners on the likelihood of neutral corrosion issues in their service territories.

Silicone Injection: Better with Pressure 

Moderate pressure injection has been utilized for over two decades and has demonstrated several significant advantages over the low pressure inject-and-soak paradigm. In 2006 sustained moderate pressure injection further advanced rejuvenation technology, increasing post injection reliability.

This paper traces the evolution of injection pressure in dielectric enhancement technology and compares the merits of the available delivery methods. The paper goes on to introduce the latest improvement in injection technology, thermally enhanced rejuvenation.

Better Next Year

For over three decades cable rejuvenation using dialkoxysilane fluids has been the most capital efficient method to prevent cable failure due to aging resulting from all manner of defects including but not limited to water treeing, electrical treeing, and manufacturing defects. Over the last decade rejuvenation has surpassed replacement as the most utilized method of rehabilitation. The work presented in this paper utilizes very large data sets to compare the post-installation reliability of rejuvenation and replacement. The results shed light upon off-line partial discharge diagnostic testing. Either or both of the following propositions are true: (1) Electrical trees are rare and/or (2) rejuvenation adequately addresses electrical trees. Data to support both propositions are presented.

Rejuvenation Upgrade

The case for a rejuvenation upgrade is even more compelling than the original case for treatment. Thirty years of experience all but eliminate the technology risk. A cable’s neutral condition has a baseline measurement which can be compared to the current condition. This comparison allows accurate extrapolation to future periods. Next-gen fluids are designed to deal with all significant aging mechanisms including ephemeral partial discharge. A cable’s suitability to be treated is pre-established. Early field results will be reviewed.

Can Novinium brand injection be capitalized? Based upon the information provided, a company may capitalize the cost of installing injection rehabilitation products provided that the product is used by the company to extend the useful life of its segments of URD cables beyond their original estimated useful lives.

RUS Letter Order Approving Capitalization of Novinium Brand Product

On September 4, 2008, the Federal Energy Regulatory Commission (FERC), acting upon a request from the manufacturer, issued Docket No. AC08-143-000, approving the capitalization of the cost of the injection rehabilitation products for underground cable (URD) known by the product names Perficio and Ultrinium, which are manufactured by Novinium, Inc. Based on the actions of the FERC, the Rural Utilities Service now authorizes the capitalization of the cost of Perficio and Ultrinium injected into underground cable.

Molecular Thermodynamics of Water in Direct-Buried Power Cables

Water, which is almost always present at 100% relative humidity at the typical 1 meter burial depth of direct buried power cables, moves very quickly through any polymeric layers. This paper examines what actually happens to water within a direct-buried cable throughout the day and year as the cable temperature, the soil temperature, and the water content of the soil vary.
