MEDIUM VOLTAGE THREE CORES CABLE WITH LEAD SHEATH

With the global renewable energy expansion, the demand for submarine power cables is steadily increasing. Embedded into the seabed, these cables interconnect the power grids of countries, as well as offshore wind farms and oil & gas platforms with the mainland. Our submarine turnkey solutions encompass the whole cable system: Design engineering, manufacturing, supply, installation, and testing.
