Product Description

AC submarine cables are widely used for mid-to-long-range application at medium-to-extra high voltage grade.  LS Cable & System can offer both single- as well as three-phase AC cables. They can be easily connected to the onshore AC power grid. Commonly, extruded cross-linked polyethylene (XLPE) is used as conductor insulation for reliable operation and maintenance, simple connection and repair, and due to its advanced chemical and electrical features.

 

Types and Purposes

•  Submarine cables for power connection
    - Connection among countries
    - Connection between islands and mainland

 
•  Submarine cables for wind power
    - External network submarine energy cables (offshore substation toonshore substation)
    - Internal network submarine energy cables (between offshore wind turbine power generators and -offshore or onshore substation) (these are referred to as “infield” or “array” cables).

• Oil & Gas
   - External network submarine energy cable (offshore oil & gas platform to onshore substation)
   - Internal network submarine energy cable (between offshore oil & gas platforms)

 

Benefits

LS Cable & System has the capability to produce long-length AC submarine cables (without the need to joint two lengths offshore), as the company possesses facilities and technology required to manufacture, factory-joint, layup (three cores), and store long-length MV and (E)HV AC submarine cables. XLPE insulated submarine cables hold many benefits, most notably, there is no risk of environmental contamination, as is given when an oil-insulation based cable is damaged.

 

Main features

 • Mid-to-long-distance transmission (100km)
 • Maximum voltage: 400kV
 • Maximum conductor size: 2,500mm2 (single core)
