Anti-Theft Cables And Solutions
cable theft is phenomenon which is closely linked to the copper price level
Cable-theft under operation causes high costs Telecom networks Railway networks Energy distribution networks Subsequent costs of cable-theft exceed the direct material loss dramatically Example United Kingdom (2012): Direct cable/material losses 30 M Estimated disruption costs 900 M ( 30x material losses)
Special risk cables in railway networks Bonding cables DC return current cables Typical cross sections 25 70 mm² Typical cross sections 400 500 mm²
Nexans RHEYRAIL Copper contamination Outer protection layer as a mix of galvanize steel and tinned copper wires Galvanized steel wire in the center and outer layer Halogenfree, black HD-PE sheathing with blue stripes Inner copper conductor, class 2
Enhanced anti-theft requirements Complicate cutting of the cable Complicate recycling of the copper by means of contamination Complicate stripping or burning of the cable sheath Improve monitoring capability for fast detection and localization Prevent bypassing or manipulation of the monitoring wires Three insulated monitoring wires with 1,5 mm² conductors for R, C and R iso monitoring Multilayer, compacted copper conductor, class 2 (500 RMV) Galvanized steel wire strands integrated in the center and outer layer of the conductor to complicate cable cutting Single/double layer steel tape armoring to protect the monitoring wires against manipulation Heavy duty, flame-retardant and halogen free PUR outer sheath to complicate cable sheath stripping or burning

DuoTrack The all-in-one railway trunk cabling solution - cost efficient and globally applicable
What is DuoTrack? DuoTrack is a combined copper/optical fiber cable solution Nexans developed for DB as cost efficient fast theft-proof and vandalism-proof future-proof maintenance free trunk cabling system for regional railway lines
Why is DuoTrack cost efficient and fast? Cabling along the track DuoTrack cabling Cable laying along the track requires high share of civil works Separate OF and Cu cable laying Increased costs in difficult terrain Occasionally impossible to install in difficult terrain Cable laying at the rail eliminates the use of civil works OF and Cu cable laying in one step Identical costs in difficult terrain Applicable anywhere along railway lines
(1) Total cost savings Concrete trough cabling DuoTrack cabling DuoTrack (3x4x1.4/1x24G652.D) - 60 % DuoTrack -OF (1x24G652.D) - 30 %
(2) Total time savings Concrete trough cabling DuoTrack cabling DuoTrack (3x4x1.4/1x24G652.D) 14 weeks 4 weeks (- 70 %)
(3) Planning expenditure savings Cabling along the track DuoTrack cabling Complex and requires planning proceedings Costs uncertainties due to unforeseeable risks of civil works Simplified planning without planning proceedings Reliable and almost fixed cost budgeting
Why is DuoTrack theft- and vandalismproof? Firm and secure fastening of the cable on the rail at clamp intervals of 60 cm High clamp pressure prevents cable theft without removal of the clamps Removal of clamps is hard physical work in the danger area of the track
Why is DuoTrack maintenance free and future-proof? Long-term stability due to DuoTrack s robust design Maintenance free cable concept Compatible with all roadbed maintenance works Designed to cover long-term demand of Cu and OF Designed for interference free operation of all Cu services
Compatibility with electrified lines Researches on the compatibility DuoTrack with electrified lines spanned from 2005 to 2009 Empirical and theoretical studies delivered consistent positive results Granting of approval is expected end of this year
DuoTrack is a turn-key system Cable (Cu+OF or OF) Accessories/ Cabinets Laying Technology Clamps and Cable Branches
DuoTrack implementation in Germany Nexans implemented DuoTrack in Germany as a turn-key-system with two consortial partners Voestalpine SIGNALING Sainerholz GmbH for cable laying technology and materials Telent GmbH for project management, installation, commissioning and documentation

CPR in Railways
CPR Construction Product Regulation The European Union EU decided to transfer the Construction Products Directive (CPD) into a Construction Products Regulation (CPR) Regulation (EU) No 305/2011 of the European Parliament Council of 9 March 2011 CPR has became effective 1 st of July 2013, will be applicable with a transition period from 1 st of July 2016 to 1 st of July 2017 and will become mandatory on the 1 st of July 2017. EMEA-ID - R&TI Bruno Weider 2016
CPR for Railways Networks CPR application for Railway Networks EU Regulation N 1303/2014 EMEA-ID - R&TI Bruno Weider 2016
CPR for Railways Networks CPR application for Railway Networks EU Regulation N 1303/2014 4.2.2.4. Requirements for electrical cables in tunnels This specification applies to all tunnels of more than 1 km length. In case of fire, exposed cables shall have the characteristics of low flammability, low fire spread, low toxicity and low smoke density. These requirements are fulfilled when the cables fulfil as a minimum the requirements of classification B2CA, s1a, a1, as per Commission Decision 2006/751/EC.

Conclusions A safe traffic control is supported by signalling systems which need to be robust and reliable. Cables play an important role as they are the backbone for the signal/data transmission of these systems. Nexans is continuously developing new solutions adapted to the needs of the Infrastructure networks, with special emphasis in the safety topics. Safety is Nexans priority in our organization, in the same way we also work to translate this key factor to our products.
