• HVAC (High Voltage Alternating Current) Cables:
These cables are used for transmitting electricity from offshore power generation sources (e.g., wind farms) to onshore grids.
They consist of a conductor (usually copper or aluminum), insulating layers, and protective armoring.
HVAC cables are Suitable for shorter distances (up to 100 km) due to reactive power loss.

• HVDC (High Voltage Direct Current) Cables:
These cables are used for long-distance power transmission, often exceeding 100 kilometers.
They include a conductor, insulation, and protective armoring. HVDC systems require converter stations at both ends.
The advantages of HVDC cables are lower electrical losses over long distances and better for connecting asynchronous grids.
