Submarine Cable: The cable is specifically designed for underwater or submarine applications. Submarine cables are used for power transmission between land-based power stations and offshore installations or between different land masses.
Submarine cables are used in various applications, including interconnecting power grids, offshore wind farms, and undersea power distribution. They are designed to withstand the harsh conditions of underwater environments, including water pressure, temperature variations, and potential mechanical stresses.
