Transport for Wales infrastructure
Rail infrastructure, station upgrades, and transport projects across the South Wales network.
Commercial development
Major commercial and mixed-use development in central Cardiff and the waterfront.
Utilities and Wales & West Utilities
Substation upgrades and HV/LV network improvement programmes across Wales.
Industry Sectors We Cover in Cardiff
The automated cable pulling system delivers across every major sector active in Cardiff and Wales. Each sector below links to a full overview of how the system performs in that environment.
Coverage & Mobilisation
Cardiff and South Wales projects can typically be mobilised within 48 hours.
Areas We Also Cover
Eight Reasons the Automated System Outperforms Manual Cable Pulling
Grooveless Powerball Design
Eliminates jacket abrasion and cable damage during installation — the most common cause of cable degradation in traditional pulling methods. Cables arrive undamaged, every run.
Up to 25 m/min Pull Speed
Sustained automated pulling at speeds impossible to maintain manually — dramatically shortening programme time on large installations. HV, MV and LV cable on cable ladder systems.
40 Pullers Per Inverter
A single power panel co-ordinates networked automated pullers across the entire cable run simultaneously — no sequential manual repositioning, no crew bottlenecks.
Dual-Motor Drive
Each puller uses two motors — delivering superior pulling strength, better stability, and sustained performance on demanding cable ladder runs without force spikes.
Precision Scale Display
Detailed scale display gives both experienced engineers and new operators clear, accurate read-outs of tension, speed and force throughout every pull in real time.
Adjustable Ball Spacing
Ball spacing adjusted with a standard spanner — rapid reconfiguration between different cable types and ladder geometries on the same project without specialist tooling.
Reduced Manual Handling
Full automation significantly reduces musculoskeletal strain and injury risk on every run — lowering CDM exposure, fewer operatives required in confined and difficult-access spaces.
Cable Ladder Specialist
Purpose-built for heavy cable on cable ladder systems — the containment type where automated pulling delivers its greatest advantage. HV, MV, LV across all commercial sectors.
Fully Automated. Controlled Tension. Every Pull.
The Corelay system replaces manual effort with precision mechanical automation — reducing installation time, eliminating cable damage, and delivering a consistent, certifiable result on every project in Cardiff.
Site Survey & System Configuration
Corelay engineers survey your cable routes on cable ladder systems and configure the automated system for your specific cable type, size and route requirements before mobilisation.
Powerball Positioning Through Ladder Containment
Automated pullers are positioned at calculated intervals through the cable ladder. The grooveless Powerball design prevents cable jacket abrasion throughout — eliminating the primary failure point of conventional methods.
Fully Automated Pull
Up to 40 pullers per inverter operate simultaneously at speeds up to 25 metres per minute. The system does the work — fewer operatives required, no manual strain, no force spikes that damage cables.
Certified Handover
All installations are tested to BS 7671 by our NICEIC-approved engineers. Full certification, EICR reports and test documentation provided — ready for your client handover pack or compliance records.
Why Not Just Pull?
A conventional winch accumulates tension along the entire cable run — peaking above 8,000 lbs at the head. Our distributed drive resets tension at every unit, keeping each section under 300 lbs and eliminating snap-back risk entirely.
