2 Our passion brings power to life Foreword Electrical energy is the lifeblood of our modern society, It affects every aspect of our daily lives, providing heat and light, acting as a driving force and supporting communication, as well as setting electric trains in motion. Electrical energy must therefore be in constant supply and we have to be able to put it to use cost-effectively. NKT has set itself the aim of helping its customers in energy supply and industry to meet this challenge by providing creative ideas and tailor-made energy transmission media. Contact wires with a service life at least two times longer than that of conventional copper contact wires and demonstrably more cost-effective than copper/silver contact wires are our most recent development innovation. The name of this new contact wire is: VALTHERMO VALTHERMO has already demonstrated its impressive properties on several reference routes. These references, which you will find on the last few pages of this catalogue, speak for themselves. Working in close collaboration with the Technical University of Dresden, we have created a rigorous economic efficiency calculation. The result is the reward for many years of dedicated development work from which you, our customers, can now benefit. But the VALTHERMO range does not just feature contact wires. It also includes catenary wires and dropper wires. We hope that you will enjoy working with the products in the VALTHERMO range and we look forward to hearing from you.

27 The project: New Lower Inn Valley Railway ÖBB high-speed rail link in Austria s Tyrolean Unterland. Providing access to the Brenner Base Tunnel from the north, the New Lower Inn Valley Railway is part of TEN axis no. 1 which links Berlin and Palermo. TEN stands for Trans-European Networks, an initiative funded by the European Union to transform and develop the single market and improve the economic and social cohesion of the EU. The programme is also designed to unify transport systems in the EU. Key Facts: 40 km double-track stretch between Kundl and Baumkirchen At the heart of this section of the route is the 16 km long Münsterer tunnel between Radfeld and Jenbach Total project costs EUR 2.4 billion The new section of track was handed over for scheduled operations to commence on 29 November 2012 The aim: Along with other construction projects (e. g. the new Brenner Base Tunnel), the New Lower Inn Valley Railway will reduce the journey time between Munich and Innsbruck from 1 hour 50 minutes to 55 minutes and between Munich and Verona from 5 hours 20 minutes to 2 hours 20 minutes. The contract: Retention for NKT as new supplier and party to the ÖBB framework contract in the first major project. In 2012, ÖBB named NKT as its new supplier of contact wires and catenary wires. Between January and September 2012, NKT supplied a total of 95 km of CuAg mm² contact wire and CuAg mm² catenary wire for this project via its distributor HC-ELECTRIC of Vienna, Austria. In meeting the expectations of ÖBB, the first major task for us as a manufacturer was posed by short lead times and very varied batch sizes. 27

28 References German Unity Transport Project No. 8 (VDE 8): Berlin Munich in 4 hours 28

29 The project: From 2017, high-speed trains capable of speeds of up to 300 km/h will reduce the journey time between Germany s two biggest cities, Berlin and Munich, to less than 4 hours. Work on the project to improve the transport link between East and West was approved back in 1991 by the then Federal Government. The project will make the train a genuine and ecofriendly alternative to travelling by air and car. The aim: Before construction work commenced, the journey time between Berlin and Munich was approximately 7 hours. However, of equal priority to reducing the journey time between these two major cities was establishing a link to the new German states. The journey time from Dresden and Leipzig in the East to Frankfurt-am-Main and the Rhine-Main region in the West, for example, is significantly reduced. The contract: NKT was selected to supply contact wires and cables from one of the route to the other, with particular involvement in the provision of highspeed contact wires. With short and reliable lead times, NKT showed itself to be a helpful project partner along the entire route for Spitzke SE, Europten, SPL and BBR, the companies responsible for the construction work. Until the end of 2016, a total of 400 t of contact wire and 300 t of cable will have been supplied to the project. Key Facts: Track length 200 km including for goods traffic At the heart of the project and also a challenge was crossing the Saale Valley and the Thuringian Forest Total costs EUR 10 billion Modern, high-performance rail hubs which also integrate regional traffic are being created in Erfurt, Halle and Leipzig From Cologne to Rhine-Main, Nuremberg to Ingolstadt and before that from Berlin to Hanover, NKT has played a vital role on all major high-speed routes in Germany. 29

31 The project: This construction connects the northern side of the Alps with Erstfeld in the Uri Valley with Bodio in the Canton of Tessin on the south side. At 57 km, it is the longest railway tunnel in the world. A continuous track runs through each of the east and west tubes. As the tunnel is what is known as a flat route, it is suitable for use by high-speed trains. The contract: Development of innovative solutions and delivery of catenary products. The construction of the Gotthard Base Tunnel has involved the installation of 2800 km of cables for power supply and data transmission, 170 km each of CuAg contact wire (120 mm 2 ) and Bz catenary wire (70 mm 2 ) as well as 850 km of copper cable and more than 100 km of aluminium cable in various cross-sections for feed and return purposes. All contact wires and cables are being supplied by NKT. In collaboration in this, the largest railway tunnel project in the world, NKT was yet again able to demonstrate its skills as a technology leader. Many years of trustful cooperation with our contractors, thorough preparation for projects with the flexibility to adapt planning and installation schedules all of these features set us apart and are valued by our customers. Key Facts: At 57 km, it is the longest railway tunnel in the world. Construction work commenced in 1999 and the tunnel went into operation in December 2016 Approximate costs approx. CHF 12 billion NKT contracted by the Transtec Gotthard Consortium Building contractor is AlpTransit AG Installation of 228 km of track and 190,000 concrete sleepers Installation of 2800 km of cables for power supply and data transmission Supply of 170 km of CuAg contact wire 120 mm 2, supply of 170 km of Bz catenary wire 70 mm 2, supply of 850 km of copper cable and more than 100 km of aluminium cable for feed and return purposes 31

32 VALTHERMO Success that speaks for itself 32

33 In comparison with other materials, the VALTHERMO contact wire has been in commercial operation with the DB rail network since 2012, and in the meantime also by other rail operators. Since 2013 VALTHERMO contact wires have been used succsessfully in local traffic. This has demonstrated two major advantages for VALTHERMO compared to Cu-ETP contact wire: considerably more service life considerably more than double the service life a lower creep strain by a factor of approximately 1:3 to 1:2 That means: 1. A saving of one or a number of contact wire replacements over the system s life. 2. The cost of adjusting the initial contact wire installations is cut, or even avoided altogether. VALTHERMO exhibits exactly the same creep strain as CuAg0.1. The adjustment cost savings mean that VALTHERMO pays for itself in the very first year. The remaining installation characteristics are the same as for Cu-ETP and CuAg0.1. A survey conducted in April 2017 on the installation properties of VALTHERMO contact wires confirms that in practice application is comparable to Cu-ETP and has a slight edge over CuAg0.1 contact wire. 3. Significant economies in terms of operating and maintenance. An analysis by Dresden University of Technology based on the Net Present Value method demonstrates that a mainline overhead contact wire system can be operated for more than 70 years without replacement. This economic benefit was also confirmed for local transport by Dresden University of Technology in 2015: over a period of 70 years the percentage of the savings resulting from the change in contact wire as compared to Cu-ETP amounts to more than 80% throughout its life cycle a clear benefit of VALTHERMO. Cu ETP CuAG0.1 VALTHERMO lower creep strain by a factor of 1:3 to 1:2 4. The longer service life and lower adjustment cost translates into significantly higher contact line system availability. 5. VALTHERMO contact wires are mechanically (tensile strength, hardness, modulus of elasticity, torsional characteristics, coefficient of expansion etc.) and electrically (conductivity, thermal coefficient of electrical resistance) fully compatible with Cu-ETP and CuAg0.1-contact wires. The clamps and other accessories used for Cu-ETP and CuAg0.1 can also be used unchanged for VALTHERMO. Cu ETP CuAG0.1 VALTHERMO 6. VALTHERMO contact wires comply with EN Furthermore, DB have evaluated the field test, have technically approved VALTHERMO and have adopted it into the Ebs-Zeichnungswerk (set of standard drawings for German railways). 33

34 The economic alternative to Cu- and CuAg Overhead Catenary Systems VALTHERMO VALTHERMO is the new contact wire material from NKT. Copper and copper-silver contact wires can now be replaced by the VALTHERMO economic alternative. Compared with copper contact wires, VALTHERMO provides higher wear resistance, higher thermal resistance and lower creep strain while achieving the same high level of conductivity as copper and copper-silver contact wires. In harmony with sustainability objectives: Multiple lifetimes and resource conservation VALTHERMO contact wire is a sustainable product: A saving of over 5,500 t CO 2 in manufacture and operation per 100 km of twin-rail track fitted with VALTHERMO contact wire can be achieved. 1) Saving on contact wire changes and reduced wear conserves resources thanks to lower Cu consumption and Cu input into the environment. 1) In comparison to Cu-ETP contact wire. Approximately 62 MWh of energy are required for the manufacture of 100 km of AC-100 contact wire. (Factor of 0.6 kg CO 2 per kwh, information from Environmental Federal Office for Electric Power). In addition to this, considerable CO 2 savings are achieved over the total lifetime of 70 years thanks to wear-related lower cross-section of the contact wire which as a result reduces losses in electricity. A wide range of application areas for VALTHERMO In the first instance, VALTHERMO is used as a cost efficient alternative to CuAg0.1 while fully complying with EN Field test results show that VALTHERMO contact wires have a longer life expectancy as compared to CuAg0.1, both when used with alternating current and with direct current. Due to more stringent requirements on contact line system availability and power transmission capability, replacing copper contact wires (Cu-ETP) with VALTHERMO is also strongly recommended. The permissible constant temperature of 80 C for Cu-ETP can be increased to a minimum of 100 C in the case of VALTHERMO, just as it can be done in the case of CuAg0.1, without any thermal softening. Thermal resistance as well is significantly higher when subjected to thermal stresses and in particular to local overheating (e.g. with a stationary pantograph). In the long term, other products made of VALTHERMO, such as messenger wires, are also the preferred economic alternative when compared to copper or copper-silver cables because of their high thermal resistance and lower creep strain. 34
