Conductors to Brazil
Nexans has been awarded a
€26 million contract by EBTE, the
Alupar company responsible for the
construction and development of the
electric power infrastructure in the
Brazil state of Mato Grosso, to supply
AAAC (all aluminium alloy conductor)
for the construction of five new 230kV
overhead transmission lines with a
total length of 775km.
The project (ANEEL 04/2008 group D)
will provide additional transmission
capacity to handle the output of a
number of new power generation
projects that will contribute to Mato
Grosso’s economic development as
well as increasing Brazil’s national
power generation capacity. AAAC
overhead conductors replace the
steel core and pure aluminium outer
layers found in conventional ACSR
(aluminium conductor steel reinforced)
conductors with aluminium alloys.
This conductor is both lighter and
stronger than ACSR, making it ideal
for long spans, as well as being more
resistant to corrosion. Using AAAC will
enable EBTE to reduce the total
number of pylons required for the
project by around 8%.
Each overhead transmission line will
comprise three phases, so Nexans
will supply a total length of around
2,350km of conventional round wire
AAAC with a cross-section of 456mm2.
The conductors, which will be manu-
factured at Nexans’ Lorena plant in
Brazil, are scheduled for delivery in the
second half of 2009, while EBTE plans
to begin operation in the second half
of 2010.

Nexans has been awarded a contract
by Global Marine Systems, provider
of submarine cable installations, to
supply 1,300km of repeatered fibre
optic submarine cable to connect
the islands of Trinidad & Tobago to
Suriname via Guyana.
The cable system will help enhance
communication links between the
three countries.
The 1,300km cable will be produced
at Nexans’ factory in Rognan, Norway
and comprise 21 segments with
amplifiers integrated every 70km.
It will be delivered to Global Marine
Systems in October 2009.
Behind this next generation of
repeatered fibre optic submarine
systems are Nexans, Global Marine
Systems Ltd and Huawei Marine
Networks, a Chinese manufacturer of
telecom accessories.
“The latest repeatered optical cable is
a major technological breakthrough
that will enable us to deliver cables
for any optical transmission range,”
says Yvon Raak, Nexans’ chief
corporate officer in charge of the
Europe area.
