Malta-Sicily interconnector reaches testing phase

The 120 kilometre Malta-Sicily subsea interconnector has reached testing phase after a year-long delay.

Enemalta is planning to commission the $216m (€182m) subsea cable, stretching from Qalet Marku in Magħtab to Ragusa in Sicily, by the end of June. The final piece of the jigsaw fell into place last week when the Magħtab Terminal Station was hooked up to the local grid by means of a 6.5 km tunnel excavated to Kappara.

The project is a year behind schedule, due to delays in acquiring planning and environmental permits from the Italian planning authorities.

Measuring 26 centimetres in diameter, the interconnector consists of three single-core 630-square-millimetre copper cables, bound up tightly together with steel wire.

The cable is covered with an additional insulation layer made of lead to prevent any water seeping in. It also houses space for two fibre-optic cables which may be used for data transmission.
