Three Core Steel wire armored Submarine Cable
Three Core Steel wire armored Submarine Cable Application
Three Core Steel wire armored Submarine Cable is is mainly intended for the solidly earthed system with power frequency 49~61Hz with rated voltage 35Kv and below, Used as high power electrical transmission between the mainland and the islands, island to island, mainland to the platform and between the offshore oil drilling platform, as well as control signals transmission of smart grid and communication signal transmission cross rivers, harbor, or the drilling platform or connection between drilling platforms, etc..
In general, the power transmission of submarine cable is undoubtedly more expensive than overhead cable with the same length, but it is more economic compare to using a small isolated power station to supply a region’s power, especially more benefits in the offshore area application.
The cable is widely used in Countries where have many islands and rivers.
