Electrical termination systems win Network Rail approval
Ian Woodcock, business development manager at Wago Limited, explains the company’s role on some major projects across the network.
W
ago’s innovative electrical termination systems improve performance, save
space and reduce cost. That’s why they’ve been specified for some of the UK’s major rail projects, including Thameslink and the Watford Remodelling Signalling scheme.
Wago, the innovators of the world-renowned Cage Clamp termination concept, offer a range of more than 25,000 products including industrial rail-mounted/PCB terminal blocks, electronic modules, interface units and fieldbus-independent I/O systems. They are used in a wide variety of applications including manufacturing, building services, utilities and transportation systems.
The Cage Clamp system ensures faster connection than conventional screw-type systems. ‘Proportional clamping’ means the spring adjusts automatically to conductor size, so a safe, secure connection is assured, virtually regardless of operator skill.
In rail transport, Wago’s spring pressure technology offers particular advantages for many on-board and trackside applications. Compared to both screw-type connectors and stud-type connector blocks, Wago units are faster to install, more compact and ensure a secure connection, which is resistant to vibration and extremes of temperature and climate.
Products have been used successfully in rail 170 | rail technology magazine Apr/May 14
systems throughout the world. Applications include locomotives, rolling stock, points heaters, signalling systems and other trackside installations. The versatility of the Wago range is a major plus. The choice of units, including double and triple deck terminal blocks, incorporating knife disconnect, test points, bridging and other functions, makes it easy to adapt to changing operator requirements.
Wago’s Series 280-675 and 280-833 TS35 DIN rail-mounted terminations have Network Rail acceptance. Amongst other Wago products used in rail applications is the X-COM S universal connection system. Suitable for use in switchgear cabinets in locomotives and carriages, it offers major labour and cost-saving benefits. The X-COM S product family provides the benefit of ‘pluggable solutions’ for a variety of switchgear applications. With a rating of 500 V/16A, the system is also an efficient and cost- effective alternative to heavy connections.
Wago continues to work closely with Network Rail and its suppliers with a view to providing truly innovative solutions for rail applications. The main aim is to help improve efficiency and maintain safety standards whilst at the same time driving down cost.
A recent example of Wago’s problem-solving approach is its work with a major rail supplier on the prestigious Thameslink project. With space-saving a key objective, Wago was able to produce new separators for its Network
Rail approved terminals – already widely used in signalling projects – that are only 1mm wide. These are replacing the 5mm versions previously used.
Another Wago product range currently going through the Network Rail approval process is TopJob S. These EX approved DIN rail mounted terminals are robust and economical and offer major space-saving benefits. In the Watford re- modelling project, they are expected to play an important part in helping solve disconnection problems associated with larger cable sizes.
