Submarine Systems

Submarine Systems Cable

The submarine systems field is facing a number of new challenges. Among them sharp increase in power demand, strong orientation towards the development of renewable energy sources and optimisation of the existing generation capacity.

In this scenario, the total cost of the submarine energy system may be the determining factor for the implementation of a project. The availability of innovative solutions together with a comprehensive know-how of all phases of the project will become essential. With this in mind, know that Prysmian is the acknowledged world leader - both in terms of market share and technical know-how in the submarine energy system field.

Extruded insulation cables

 The extruded dielectric offers many advantages that make the cables lighter and easier to handle and to install. Both EPR and XLPE can be used for insulation: they provide the cables with the advantage of operating at high temperatures (90°C) and at high electrical stresses. In most cases, XLPE requires an impervious metallic sheath (e.g. lead sheath) to be applied over each core to avoid direct contact with water. EPR compounds can be formulated in such a way as to give an excellent performance in terms of both electrical reliability and ageing, thus removing the need for an impervious metallic sheath (the so called "Wet Design"). We tailor-make your solutions In order to meet different standards and preconditions we always tailor-make the cable...

Mass impregnated cables

 These cables are presently suitable for voltages of up to 500 kV DC. The insulation consists of high-density paper tapes impregnated with a high-viscosity compound, which does not require fluid pressure feeding. These cables can be installed in high voltage DC links in very long lengths, up to several hundreds of kilometres. Present experience or trials are limited to water depths in the range of 1000 m, but deeper waters can be reached by using special design features. We tailor-make your solutions In order to meet different standards and preconditions we always tailor-make the cable systems in this area. Please contact our experts to specify your requirements.

Self-contained fluid filled cables

 These cables are presently suitable for voltages up to 600 kV DC. They can be laid at depths down to approximately 800 m without special precautions; with the use of special fluids and proper armour designs, depths of 2000 m can be reached. The cables designs depend on the feeding length – maximum connection lengths are between 60 to 100 km, depending on system features. The longer the route, the larger the oil duct required.

Mass impregnated cables

 These cables are presently suitable for voltages of up to 45 kV AC. The insulation consists of high-density paper tapes impregnated with a high-viscosity compound, which does not require fluid pressure feeding. These cables can be installed in HVDC links in very long lengths, up to several hundreds of kilometres. Present experience or trials are limited to water depths in the range of 1000 m, but deeper waters can be reached by using special design features.

Paper-Polypropylene Laminated (PPL) cables

 PPL cables use a special low permittivity - low loss insulation type. Compared to conventional self-contained fluid filled paper insulated cables at the same power, it allows for increased transmitted power or reduced conductor size and cable dimensions. The use of PPL is in general considered for large sizes and for voltages above 275 kV.
