Global Submarine Cables Market Share, by Application, 2022

The submarine power cables sub-segment accounted for the highest share in 2022. The global shift towards renewable energy sources, such as offshore wind farms, has driven the demand for submarine power cables. These cables are used to transmit electricity from offshore renewable energy installations to onshore power grids. As countries invest in renewable energy projects to reduce carbon emissions and increase energy security, the demand for submarine power cables increases. Countries and regions are increasingly establishing power interconnections through submarine power cables to share electricity and optimize energy resources. These interconnections help stabilize the power supply, facilitate energy trading, and enhance grid resilience. Many islands and remote coastal areas rely on submarine power cables to connect to the mainland power grids. This electrification process aims to improve energy access and economic development in such regions.

Global Submarine Cables Market Share, by Voltage, 2022

The high voltage cables sub-segment accounted for the highest share in 2022. High voltage cables can transmit power over long distances with lower energy losses compared to medium and extra high voltage cables. As voltage increases, the current decreases for the same power transfer, reducing resistive losses along the cable. Transmitting power at higher voltages permits more effective power transmission. This is important for long-distance power transmission. Although high-voltage cables require more insulation and specialized equipment, the reduced energy losses and the ability to transmit larger amounts of power over long distances make them more cost-effective in the long run, particularly for large-scale power transmission projects. High-voltage cables can transmit the same amount of power as lower-voltage cables using smaller conductor sizes. This means less material is required for construction, making the cables more lightweight and easier to handle during installation.

Global Submarine Cables Market Share, by End-User, 2022

The offshore wind power generation sub-segment accounted for the highest share in 2022. Offshore wind farms are located far from the coast in open waters where traditional overhead power lines are not practical.
