Degradation of silicone insulating fluids in cable sealing ends
Degradation of silicone insulating fluids in cable sealing ends
Polymeric cable sealing ends (CSE) typically contain silicone oil as an insulating fluid. In recent years a number of performance issues have been identified with silicone filled CSE on the UK network. In order to manage these assets effectively, it is important to investigate possible reasons for the unexpected service experience. This paper presents a review of the properties of the silicone fluid, the outcomes of measurements and chemical analysis on a range of samples of new and used silicone fluids. We also present the results of a fully three dimensional thermal and electrical finite element model of the CSE, which helps to demonstrate the conditions experienced by the silicone fluid when in service in a CSE.

Abstract
Polymeric cable sealing ends (CSE) typically contain silicone oil as an insulating fluid. In recent years a number of performance issues have been identified with silicone filled CSE on the UK network. In order to manage these assets effectively, it is important to investigate possible reasons for the unexpected service experience. This paper presents a review of the properties of the silicone fluid, the outcomes of measurements and chemical analysis on a range of samples of new and used silicone fluids. We also present the results of a fully three dimensional thermal and electrical finite element model of the CSE, which helps to demonstrate the conditions experienced by the silicone fluid when in service in a CSE.
