ZTT - Model HVDC -Submarine Cable
HVDC links are mainly used for the transmission of large amounts of power over a long distance with low losses, especially for offshore generation sites that are far from shore (>70km). HVDC submarine cables are typically single-core cables with extruded insulation and metallic radial water barrier. ZTT has the capability of manufacturing the HVDC submarine cables with an annual capacity of 1000km and had made a series of great achievements in Chinese market.
ZTT has the capability to manufacture long continuous length HVDC submarine cables without factory splices with the state-of-the-art VCV lines and large indoor turntables for transferring and store the long length complete submarine cables with two big outdoor turntables to deliver in one segment without necessity of using offshore joint. Moreover, the rather short length (80m) for cable loading out to the vessel calling at the wharf greatly reduces the risk during the process.
