We have a lot to say about cable reliability, rejuvenation, injection processes and more. To help you find the right stuff, search by category or keyword. Want the big picture? There’s always the site wide search at the top.

CO2 v Helium

CO2 v Helium Q: Novinium uses CO2 gases to push their fluids, and not helium. Why is that so? Is there a benefit of one over the other? Does the CO2 contribute to global warming? A: There are safety, environmental, and economic benefits of using CO2. Safety Benefit Effervescence limits the conductivity of fluid effluent…

Methanol

Methanol Matters

Q: Methanol is both poisonous and explosive. What precautions will be taken by the circuit owner or Novinium if the cable, cable components, or injection equipment were to leak Cablecure 732 fluid and mix with water (i.e. flooded vault scenario)?

Flash Point Matters

Q: Why is the flash point of a rejuvenation fluid relevant? The temperature of an electrical arc is 35,000°F. And everything is flammable from the utility standpoint, just as nothing is unbreakable from a lineman’s viewpoint.

Methanol

Q: In Section 16 of the material safety data sheet (MSDS) for Cablecure iXL fluid it states that methanol is listed as a Hazardous Air Pollutant (HAP). Given your green credentials it is hard to believe that you would create any significant air pollution.

Dielectric IV

Dielectric IV In Dielectric I, I provided the first part of a four-part answer to a query—the summary question: To what extent does the introduction of injection equipment into energized devices impact the safe operation of medium-voltage circuits? We learned that there are great differences in the extent of this risk depending upon the injection…

Dielectric III

Dielectric III In Dielectric I, I provided the first part of a four-part answer to eight questions. The eight questions can be summarized: To what extent does the introduction of injection equipment into energized devices impact the safe operation of medium voltage circuits? We learned in the first installment that there are great differences in…

Dielectric I

Dielectric I Q: I am working on my comments/concerns for the Safety Section for the C30 Draft Guide [Editors note: C30 is a group within the IEEE/PES/ICC working towards the writing of a “Draft Guide for Rehabilitation and Rejuvenation of Extruded Dielectric Cable Rated 2.5kV through 46kV.” While that Draft is being crafted, interested readers…
