Breakdown Characteristics of PEEK Insulation Immersed in Synthetic Ester Liquid for Subsea Cable Connectors

Electrical Materials and Applications, Volume 3, Issue 1, January/December 2026.
This paper proposes integrating polyether ether ketone (PEEK) with a synthetic ester liquid as the composite insulation system for subsea cable connectors. The study commences with a comparative analysis of the electrical performance of PEEK when immersed in a synthetic ester liquid and a mineral oil.
