Subsea cable between Italy and Montenegro

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. Nexans – France Website : www.nexans.com

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

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.”
