Runway Rejuvenation: Cables Secure Critical Airport Infrastructure
“Runway Rejuvenation: Cables Secure Critical Airport Infrastructure“, Power Grid International, November 2015
After careful examination of the electrical power cable supplying the airport, DP&L determined that more than 40,000 feet of cable in two feeders needed to be replaced or rejuvenated and it was critical that it be done quickly. Ultimately, the utility determined the project needed to be completed in less than two months, leaving little time for planning and project completion.
Electrical cable rejuvenation is an alternative to cable replacement that restores feeder cable to its full dielectric strength for a fraction of the cost of cable replacement with minimal operational disruption. DP&L had completed a feeder cable rejuvenation project a few years earlier and given the short timeline for this project decided that rejuvenation was the best alternative in this case. The utility chose to rejuvenate both the 1,000 circular mils (MCM) and 500 MCM feeder cables supplying the airport. It chose Novinium to execute the cable rejuvenation.
