Bonding / Coupling systems are used to create zones of electrical equipotential

John Maher
Challenges regularly arise on railway projects and that is half of the fun. If a challenge presents significant impacts or difficulties experience really does become of considerable value. The substantial experience within our organisation feeds innovation and helps refine our approach, and it is this critical difference which results in the JMI element of the FM Sudafix Group truly surpassing other sector companies.

Question

Bonding / Coupling

Determining the appropriate bonding / coupling arrangement on a railway system requires experience and informed judgment. Equipotential bonding installations on light rail systems also demand the consideration of potential conductive elements that fall within the 'drop zone' in the event that an overhead power line snaps.

  • The amount of rail to rail, and track to track bonds required for a given system, or indeed, a given section of a rail system is subject to the build specification, system wide earthing / grounding policy, codes of practice and standards. Familiarity with these sorts of documents enables a designer to determine an appropriate system, and provide the installation team with an effective arrangement.
  • Rail bonding / coupling involves equipment, structure, and continuity elements and must be effective to vouchsafe the ongoing reliability of the railway system.
  • Appointing a reliable associate company for electrical safety systems is important. JMI, as part of the FM Sudafix Group, can specify, design, supply, install, commission and test bonding / coupling arrangements on railway systems.


Electrical safety products for railways

Cable Lugs

Cable Lugs

Enabling users to terminate electrical cables, whilst enabling them to be joined to other conductive elements, high conductive cable lugs provide the practical solution.
Heat Shrink

Heat Shrink

One of the defining characteristics of professionally manufactured cable bonds of any sort is the presence of heat shrink at joins and connections.
