Nexans has been awarded one of two contracts for the supply
and installation of a power cable for the high-voltage direct
current (HVDC) link between Italy and Montenegro.
The public tender was called by Terna Rete Italia SpA, a company
fully owned by Terna SpA, the operator of Italy’s electricity
transmission system.
Over the last 20 years, Nexans has manufactured and installed
over 3,000km of HVDC submarine cables.
The new link will connect the Italian peninsula with the Balkans
and will contribute to improve the integration of the countries’
electricity systems.
The HVDC interconnection between Italy and Montenegro will be
approximately 415km in length, comprising 393km of subsea cable
and 22kmof underground cable for the onshore connections.
It will feature two 500kV HVDC cables in a bipolar configuration
(2 x 500MW), with one cable supplied by Nexans.

Subsea cable between Italy and Montenegro
Cable cleats rush to
Russia
Yorkshire cable cleat manufacturer Ellis
has won the order to supply extra high
voltage (EHV) cable saddles to a unique
Hydro Accumulative power plant in the
Moscow region.
Ellis’ Centaur cable saddles were
specified by Russian cable engineering
and cable supply company Systec
LLC for use in the second phase
development of the Zagorskaya pumped
storage plant (PSP), located in the
administrative district’s Sergiev Posad
area.
The plant uses two lakes at different
altitudes to generate sufficient power
to cope with peak demands in Moscow,
and when complete will deliver
1,200MW of generated power and
1,320MW of consumable power.
Centaur is a heavy duty extruded
aluminium saddle cleat, designed and
developed in-house by Ellis in response
to a serious safety issue surrounding the
restraint of high voltage (HV) and EHV
cables up to 160mm in diameter.
Prior to launch, Ellis put its Centaur
cable saddles through the most
rigorous of testing procedures. The
company shipped the saddles to the
Netherlands, where they were tested
on EHV cable to 163 kA peak and 63 kA
RMS for one second, in both 3 phase and
phase-to-phase fault scenarios.
Pavel Udovitsky, a senior project
manager for Systec, said: “We knew that
Ellis had developed a cable cleat for
EHV cables and when we spoke to them
about the benefits it would bring to
this project, the answers they provided
left us in absolutely no doubt that its
Centaur cable saddle was the ideal
specification option.”
