Design and manufactureRail Track ApplicationsRAIL TRACK

Tranect Ltd designs and manufactures copper electrical connections, cable assemblies, terminals and earthing components for rail track, signalling, traction-power and overhead-line applications.
Rail infrastructure operates in a particularly unforgiving environment. Electrical components may be exposed to continual vibration, mechanical movement, moisture, contamination, temperature variation and high electrical fault currents. Connections must remain electrically reliable while tolerating movement between rails, structures, cables and installed equipment.

Overhead-Line Applications

Copper connections are used throughout overhead-line equipment and associated power-distribution infrastructure.

Typical applications include:

Catenary wire clamps
Cable clamps
Gantry and mast earthing
Transformer and feeder-station connections
Switchgear and isolator connections
Cable-to-busbar interfaces
Flexible connections between fixed equipment
Earthing of cabinets, enclosures and trackside structures
Substation and distribution-system connections

Where rigid conductors cannot accommodate alignment differences or operational movement, flexible braided or laminated copper connections provide a dependable low-resistance alternative.

Earthing and bonding

Effective earthing and equipotential bonding help protect personnel, infrastructure and electrical equipment during both normal operation and fault conditions.

Tranect manufactures:

Flexible copper earth straps
Tinned copper earth bonds
Insulated bonding straps
Copper earth bars
Braided conductor assemblies
Rail-to-structure bonding connections
Custom earthing components

Earth straps can be manufactured in a wide range of conductor sizes, lengths and terminal arrangements. Protective sleeving, identification and alternative fixing configurations can also be incorporated.

For highly corrosive locations or specialist bonding requirements, stainless-steel earth bonds are available through our dedicated stainless-steel braid division.

Obsolete Rail Components

Rail infrastructure frequently remains in service for decades, by which point original components may no longer be readily available.

Tranect can reverse engineer existing copper connections, terminals and fabricated parts from:

Original drawings
Dimensional information
Photographs
Samples removed from service
Electrical and mechanical performance requirements

Using 3D CAD, CNC profiling, machining, forming and controlled assembly processes, we can manufacture replacement components without requiring customers to redesign the surrounding equipment.

This capability is particularly useful for maintenance projects, urgent repairs and refurbishment programmes where equipment downtime must be kept to a minimum.

Built for your Application

Whether the requirement is for a single replacement bond, a special cable terminal or a production programme of traction-power connections, Tranect provides responsive engineering support and UK manufacturing.
