Japanโs Sumitomo Electric Industries (SEI) has been awarded a contract for the Stikine Crossing Submarine Cable Replacement Project from Southeast Alaska Power Agency (SEAPA) through its subsidiary, Sumitomo Electric USA.
A press release said that the project calls for removing and discarding the existing 138 kV OF (oil filled) submarine power cable. It will be replaced by an environmentally friendly 69 kV XLPE (Cross-linked polyethylene) submarine cable, with ancillary equipment, for a fully functional system located in the Stikine crossing (approximately 16,700 ft high) between Vank and Woronkofski Islands, near Wrangell, Alaska, USA. In 2018, SEI completed a similar project in relatively close waters for Orcas Power & Light Cooperative, Washington, USA.
โThe Sumitomo Electric Group will carry out this project soundly with the highest priority on quality and safety, and through constant optimization in project execution gain further experience to capture demand for power grid renewal projects in the U.S. market, which is expected to rise in coming years.โ
In other news, SEI has passed the approval test for its 525 kV DC cable system with a DC gas-insulated switchgear (DC GIS) interface in accordance with CIGRE TB496 by a collaboration with Siemens Energy and German cable supplier Sรผdkabel. DC GIS provides a compact solution for connecting HVDC cable lines to offshore converter platforms and onshore transition stations. Sรผdkabel supplied its DC XLPE cable using Sumitomo Electricโs DC XLPE compound materials and connected it to Sumitomo Electricโs XLPE cable and joints.
