The Project consists of a new HVAC link between the island of Crete and Peloponesso
TECNALIA has successfully tested in its facilities the sea-land transition joint of the electrical interconnection project between the island of Crete and the Peloponnese peninsula, in Greece.
For this, an 87/150 kV AC cable system was set up consisting of an underground cable section, a submarine cable section and a transition joint. The submarine cable and the joint were manufactured and supplied by PRYSMIAN Powerlink in Italy, using the innovative aramidic armour. The cable system was subjected to the complete sequence of type tests according to IEC 60840 Standard with satisfactory results.
The project is promoted by IPTO, operator of the electricity transmission system in Greece, and consists of electrically interconnecting the island of Crete with the Peloponnese peninsula through a three-phase alternating voltage system with XLPE insulated cable.
It is a pioneering project worldwide since it breaks several marks as it is the longest AC link in the world, both in its total length (174 kilometers) and in the submarine section (132 kilometers), and the deepest of laying (about 1000 meters).
