Prysmian – developing power transmission grids

High-speed crossings

Recycling HVDC

Prysmian Group has launched a cable technology for the development of power transmission grids, said to ensure better environmental sustainability, higher electrical performance and lower costs. The group has announced the successful development of its new P-Laser 525kV cable system for HVDC applications. P-Laser is described as the company’s most advanced technology for efficient cable production with lower environmental impact than traditional XLPE (cross-linked polyethylene). Manufactured in a single continuous process, it needs no chemical reactions to achieve the properties required for the long term electrical integrity of HVDC insulation systems. Shorter production times result in both reduced energy consumption and lower greenhouse gas emissions. P-Laser is the first fully recyclable HVDC cable, and is said to provide better electrical performance and a higher material integrity for HVDC in comparison to traditional XLPE-insulated cables. From an efficiency perspective, P-Laser technology has higher thermal performance properties, which increase the power transmission capability of the cable system for a given conductor size.

Alcatel-Lucent Submarine Networks (ASN) is to implement two major upgrades on transpacific and transatlantic undersea cable systems. The company plans the upgrades to add terabits of capacity on each route bringing more scalability and redundancy to the delivery of high speed, low latency services over resilient high capacity systems. ASN’s 1620 Softnode, with bit rates up to 400Gbps, will deliver the multi-terabit boost on both routes. “Achieving the maximum capacity out of an existing submarine network asset remains critical for telecomandweb-scale operators as they need to meet increasing end-user requirements for capacity, speed and reliability,” said Philippe Piron, president of ASN. ASN will upgrade a new cable system on the transpacific route, connecting major cities along the US west coast to two coastal locations in Japan and Taiwan. On the transatlantic route, ASN will upgrade a 6,500km submarine cable system linking the UK to the US.
