A Cable Too Long

Q: I am currently reviewing a URD circuit with a cable segment that is 6,200′ per our one-line and GIS. It is our regular #2 db [direct buried] cable. I am considering the installation of pull-boxes to break up the many long segments prior to attempting injection. What is the practical limit to TDR [time-domain reflectometer] testing? What is the practical injection limit? I assume in the best case that there at least a construction splice every 2000 feet, but there may be more that have to be replaced.

The Color of Capital

Q: My firm uses Cablecure 732 and SPR to treat cables after they fail. The ability to capitalize single section injection with Novinium technology means we can earn a regulated rate of return on the capital thus expended. I read your four-part blog, “The Color on Money” and was wondering if you could do a similar analysis to help us quantify the benefit of our approach.

The Color of Money – Part III

The Color of Money—Part III In my post of February 27th, The Color of Money—Part I, I provided the big picture answer. In yesterday’s follow-up post we delved into the details of depreciation. Today we will deliberate discounting—muse over money’s time-value. A dollar earned or saved today has a greater value than a dollar earned…

Fluid Flammability

Fluid Flammability Q: Our construction centers have posed the following questions: 1. Is the injection fluid flammable after the cable has been treated? If yes, for how long? 2. Is it safe for our crews to splice a failed cable that has been injected? What type of precautions do they need to take when working…
