Submarine Power Cable Since thirty years SCW plant in Shanghai is specialised in the design, production and installation of low and medium and high voltage submarine power cables required for river or lake crossings, power supply to islands and platforms for offshore oil and gas production and offshore wind mill parks.

Numerous successfully completed projects with our cables in China and overseas have proven the capability of SCW‘s highly skilled technical staff to cope with submarine cable design, production, transportation and laying problems.

The experience gained by SCW in the development of oil-filled and extra high voltage cables is further applied in the production of submarine power cables. Testing

Testing at the factory is done according to the specified national or international standards and furthermore in strict accordance to the rules of the SCW quality assurance recommendations.

Modern testing facilities permit extensive testing of the cables as: routine tests - special tests - type tests.

� Transportation, Laying, Field testing

Special manufacturing, storing and loading facilities for submarine power cables in long lengths have been developed at SCW including the necessary provisions for transportation to seaports and direct transfer to cable laying ships or to special loading platforms. Short lengths are supplied on special cable drums, while longer lengths are normally supplied in coils laid out on platforms or fed directly into the cable laying ship. For the actual cable laying operation, platforms can be placed by means of a floating crane on barges or supply boats. The cable is then laid directly from the coil into the water through a roller system assistance and supervision of the cable laying operation or do the installation on turnkey basis including substations and cable protection equipment. The machinery and equipment for cable laying as well as cable accessories, such as specially developed splicing kits for submarine joints and cable terminations, can also be provided. Cable testing after installation and in case of a damage fault location with modern measuring equipment can be performed by SCWs as well. which is necessary to avoid kinking. For laying the cable into deeper water a special cable laying unit which coordinates the laying speed and braking of the cable is required. Depending on the possible danger of damages by anchors or heavy fishing gear, the cable is either laid directly on the bottom or buried in the seabed using a water jet stream or other trenching methods. On request, SCWs can either provide technical

Design of medium high voltage submarine cables

SCW supplies different types of submarine power cables depending on specific

requirements and conditions at site. The cable constructions are based on the mayor national or international Standards e.g. VDE, IEC or according to customers design and standards. The scw’s Group can produce submarine power cables up to 500 kV A.C. with paper-oil insulation; our plant in Yichang is specialised in the production of submarine power cables with XLPE insulation up to 220kv and EPR insulation up to 36 kV.
