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.
