Injection Device Choices for Rejuvenating Cables

October 24, 2017

Abstract—The choice of injection devices to deliver rejuvenation fluid to aging cables has changed considerably over the past few decades. This paper tells a brief history of devices relative to how cable rejuvenation processes have evolved beyond unsustained pressure rejuvenation (UPR) toward improved unsustained pressure rejuvenation (iUPR), and sustained pressure rejuvenation (SPR), examines the injection devices and terminations utilized for modern rejuvenation, and discusses the advantages and limitations of each device type.
