The world’s longest triplex undersea bidirectional AC cable interconnection has been operating since 2020, connecting the 150 kV power systems of northeast Crete and southwest Peloponnese in Greece. This is a 2X200 MVA 135 km system, with underground cable interconnections at both ends that add another 42 km of length. The undersea cables are laid at a record depth of 980 m. This presentation reviews all the different testing requirements as well as findings related to this cable interconnection and also describes continuing work in this regard.
