No water, salt, dust or rats. No electromagnetic disturbance. None of these risk factors may affect the SAPEI HVDC link between Sardinia and the Italian mainland.
The SAPEI is a 435 km long transmission system with a capacity of 1,000 MW. The double submarine cable runs at 1,640 meters below sea level – a world record.
Energy transmission grid operator Terna and ABB Power Systems use Roxtec safety seals in the new converter stations on each side of the Tyrrhenian Sea.
“I recommend Roxtec, and I suggest we use Roxtec in our future projects too.”
