Life of Underground Lines Are Being Extended
Work on this project enters its fifth year
What is cable rejuvenation? According to Novinium’s web site (this is the vendor that GVEA has contracted with): "It’s the process of injecting a healing and upgrading silicone fluid into the strands of aging medium-voltage power cables. The rejuvenation fluid migrates into the conductor shield and insulation, modifying the insulation’s chemistry, ultimately repairing and extending the cable life. The cable returns to its full dielectric strength within as little as seven days."
GVEA has dedicated a two-person crew each of the past four summers to work with a representative from Novinium. Approximately 10,000 feet of GVEA’s underground cable has been rejuvenated each summer. This summer, we’re trying something new in the hopes of achieving a minimum of 30,000 feet of cable rejuvenation. Instead of GVEA assigning a two-person crew to work on this project, it will be a two-person crew from Fullford Electric who will be working with Novinium.
Beginning on August 21, this year’s work (2017) will last two months and will focus on the underground lines in University West.
Novinium warranties their work and believes this will extend the life of the power cables by as many as 40 years.
An additional benefit from this work: once the underground lines have been rejuvenated, GVEA’s mapping system is updated with data on the lines, making the information more complete and detailed than ever before.
