PRODUCT RANGE
HVDC MASS Impregnated Cables : These cables are suitable for voltages of up to 600 kV DC. The insulation consists of high-density paper tapes impregnated with a high-viscosity compound which does not require fluid pressure feeding, thus allowing cables to be installed in HVDC links in very long lengths, up to several hundreds of kilometres. Research and development work on materials and technologies carried out by Prysmian has led to a product that combines the advantages of PPL and MI technologies. The use of PPL in combination with a viscous compound has significantly increased HVDC cables electrical and thermal performances and paved the way for system planners to a range of unprecedented technical and economical possibilities and for bulk power transmission, exceeding 2000 MW per bipole at ±600 kV. Present experience include record breaking installation at water depths exceeding 1600 m, using special design features.
HVAC and HVDC Self-Contained Fluid Filled Cables : These cables are suitable for voltages up to 600 kV HVDC and 1000 kV HVAC. A special low permittivity - low loss insulation system consisting of Paper Polypropylene Laminate (PPL) has been developed for HVAC SCFF cables to improve electrical performances and reduce losses. Benefits of PPL insulated cables are either increase of transmitted power or reduction of the conductor size and cable dimensions in comparison with conventional paper insulated cables. The use of PPL is in general considered for bulk power transmission at voltages above 400 kV AC and 500 kV DC. Application of SCFF cables is intrinsically limited in distance by the oil feeding hydraulic system. They can be laid at depths down to approximately 2000m.
HVDC Extruded Insulation Cables : Absence of impregnating fluids and/or pressure feeding requirements, reduced cable weight and dimensions and relative ease of jointing are the key features of this technological innovation. Where system requirements permit, the use of an extruded dielectric offers several remarkable advantages and makes for lighter and easier-to handle cables, which can operate at high temperatures and at high electrical stresses. Recent developments on converters technology have led to the adoption of extruded insulation cables for HVDC transmission systems up to 320 kV, in particular when associated with VSC (Voltage Source Converter) technology.
