The Submarine cables play a consequential role under the sea and ocean to transfer energy and communicate signals around the world. These cables connect the different stations to carry all the telephonic and communication traffic.

Construction of the Submarine Cables-Submarine Cables

The submarine cables and underground cables are mostly similar in construction. The major difference between these cables is that Submarine cables can work in the unfavorable atmospheric conditions and submarine cable are strong enough to withstand hazardous conditions under the sea or ocean.
Let’s check out the basic elements of submarine cables below:

  • Outer View of cable: The outside layer of the Submarine cables consists of an extruded polymer or spiral overlay of wires. The outer layer of the polymer protects the Armour in the cable.
  • Isolation System: The isolation system protects the conductor of the cable from outside atmosphere.
  • Conductor: Manufacturers use cable copper or aluminum to make the conductor due to their better conductive properties.
  • Watertight Sleeve: This sleeve constitutes lead, aluminum, and copper which protects the isolation system and conductor from the water.
  • Semi-Conductive layers: This layer serves the purpose to create a dielectric surface between isolator and conductor.
