by Glen J. Bertini

This paper provides part I of a framework for the prediction of the effective life extension of cables treated with rejuvenating chemicals under accelerated aging conditions. Utilizing the principles of molecular thermodynamics and a cable’s soil regime, soil thermal conductivity, and load profile, it is possible to make accurate estimations of life extension for legacy technologies and for new advanced technologies.

  • Proper method to estimate post-injection performance
  • Extensive data which validates life-expectancy
  • Life extension comparison : 732 & older technology
