1 HV Light Cables Submarine and land s

2 The HV Light s to offshore platform The light and robust HV Light s can be laid with very cost effecient methods HV Light System HV Light is a transmission system in one ABB turn-key delivery including s, converters, transformers etcetera. ABB has the capability to provide the complete chain of services from design to commissioning. Applications: Power transmission Reactive control in both connected AC networks Connecting not synchronized networks, offshore platforms, wind farms etc. Main technical features are: Advantageous for long distance transmission Power reversal without interruption Can start up dead AC network No increase of short circuit s Equal or longer service life than XLPE AC s. AC Land or submarine bipole AC 2

3 We produced and installed MurrayLink, the world s longest land Cable ship for the Cross Sound Cable 330 MW feeder to Long Island - floating the end ashore HV Light Cables The system is complete with s, accessories and installation services. The s are oated in bipolar mode, one with positive polarity and one with negative polarity. The s have polymeric insulating material, which is very strong and robust. This strength and flexibility make the HV Light s fect for severe installation conditions: The submarine s can be laid in dee waters and on rough bottoms The land s can be installed less costly with ploughing technique HV s can now also go overhead with Aerial Cables. Environmentally friendly Magnetic fields are eliminated since HV Light s are laid in pairs with antiparallel s Risk of oil spill, as in pa-oil-insulated s, is eliminated. More than 1,600 km HV Light s installed: Submarine reference projects Estlink, Estonia - Finland Interconnecting the Baltic countries with the Nordic countries 350 MW at 150 kv, 2 x 75 km submarine, 2 x 29 km land, year 2006 Troll A offshore gas platform, Norway Unique and efficient combination of transmission and frequency regulated electric drives 2 x 40 MW at 80 kv, 4 x 68 km, year 2004 Cross Sound Cable, USA Fully controllable to Long Island 330 MW at 150 kv, 2 x 42 km, year 2002 Land reference projects MurrayLink, Victoria South Australia The world s longest land 200 MW at 150 kv, 2 x 180 km, year 2002 DirectLink, New South Wales Queensland Different tariffs call for trade 3 x 60 MW at 84 kv, 6 x 65 km, year 2000 Tjaereborg, Denmark Power quality and variable frequency for wind mill parks 8 MW at 10 kv, 2 x 4.5 km, year 2000 Gotland Island, Sweden Network control at extensive use of wind mills 50 MW at 80 kv, 2 x 70 km, year
