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.

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…

The Prysmian name has been synonymous with fluid filled High Voltage cable systems since it invented and introduced its range of products into service in the 1920s. With their proven electrical performance, life expectancy and excellent reliability record, these type of cable systems continue to meet the ever increasing demands of the world-wide transmission and distribution systems up to 1100 kV AC. With its long experience in the design and production Prysmian offers its own comprehensive range of High Voltage…

Extruded cables are light and easy to handle and extruded cable systems are designed to be maintenance-free. Dependent on the system requirements, these features present significant benefits in terms of total installed system cost. Prysmian produces extruded cables with either XLPE or EPR insulation material, using design and process technologies, which ensure continued service reliability and long-term performance. Such cables can operate at elevated temperatures and under considerable electrical stress. Prysmian also offers a wide range of accessories for extruded…
