The subsea interconnection of Crete to the mainland has approximately 178 Km long HVAC interconnection with submarine cables laying under the depths of up to 1,000 m. In addition, three different types of cable protection systems were custom-designed in terms of water depth, geomorphology, and geohazards along the length of 135km.
