Electrification innovations
Network Rail’s electrification programme covering key sections of Britain’s network is providing new opportunities for suppliers. Pace Networks works in partnership with Bonomi Group and Morris Line Engineering (MLE), and has been responding to the requirements of these plans. On show at Infrarail will be a notable result of this partnership – the development of a fixed earthing device (FED) by MLE in collaboration with Network Rail and a number of its main contractors.
In 2012 the Office of Rail Regulation issued new guidelines for isolating and earthing the 25kV network, with a particular focus on safety. As a result Network Rail undertook a detailed review of these practices, including the use of FEDs with local or remote operation as an alternative to the use of portable leads. FEDs are switches that can be operated to earth the overhead line for safety and maintenance purposes once traction power has been disconnected and isolated. Operation could be from central control or at a number of points along the route. MLE has now started production of these devices, which can be either manually or electrically operated. Also present on the
Pace Networks stand will be Bonomi Group, with its Omnia range of cantilevers for overhead electrification systems. Already adopted in Italy, Omnia has since been developed to suit UK requirements and is now standard equipment for ‘Series 2’ specification. It has been successfully installed on Phases 1 and 2 of the electrification programme in northwest England and on the
TE Connectivity targets electrification schemes
Major rail investment plans for the UK are also a current focus for TE Connectivity, which has created a task force combining the expertise and resources of its Rail and Energy business units to create innovative solutions for electrification requirements. The combination of the infrastructure expertise of TE Energy, which has been one of the leading suppliers for electrical networks in the UK for more than 60 years, and the industry knowledge of TE Rail has allowed TE Connectivity to leverage expertise across its businesses to offer unique solutions to the market.
The result will be on show at Infrarail – a range of products used in electrified rail systems for trackside and rolling stock applications as well as high-, medium- and low-voltage cable accessories, connectors and fittings, overhead line insulators and insulation, surge arresters and a roofline solution that all meet current rail standards.

Cumbernauld project in Scotland. In response to a Network Rail requirement, Bonomi has been developing a station cantilever for platform use. This keeps the 25kV live section of a cantilever far away from station platforms for reasons of security and for maintenance purposes. The company says Omnia’s simple but advanced design allows easy control of clearance issues and provides a wide range of reach from the mast surface to the catenary axis without losing any benefits or reliability. In addition, Omnia provides an unprecedented level of aesthetics, while whole-life costs, installation time and maintenance are significantly reduced. Since 1992 Rebosio, now part of Bonomi Group, has been a leading supplier of composite insulators to Network Rail. In Europe Bonomi Group is one of the most successful suppliers of railway overhead line equipment, including cantilevers, tensioning devices, droppers and connectors.
10 INFRARAIL 2014 OFFICIAL PREVIEW
LEM will be presenting energy, current and voltage measurements solutions for traction at Infrarail. Traction products to be displayed include the latest EM4TII Energy Meter – utilising LEM's class 0.5R ITC current (now available in the 1,000A and 2,000A ranges in addition to the 4,000A version) and DV voltage transducers. This is the only suite of components able to offer an onboard energy metering function for both DC and AC rail networks fully compatible with EN50463. For railway industry engineers working with both rolling stock and substations, LEM will propose a new versatile power saving (30% less consumption) solution that is equally applicable to measuring network voltages or the main converter DC link onboard trains. Integrating LEM’s proven and patented insulating technology, the DVL voltage transducer will exhibit flexible mechanical features and high performance, including unmatched immunity against electromagnetic disturbances. Weighing 30% less, the family of devices covers nominal voltages from 50 to 2,000V. LEM says it is the market leader in providing innovative and high quality solutions for measuring electrical parameters for a broad range of applications. The rail industry uses LEM’s products for onboard energy measurement, propulsion and auxiliary inverter control, track asset monitoring and improving maintenance infrastructures.
