TFP Electrical Fire & Security delivers Double-S smart cable pulling across every commercial sector — offices, data centres, hospitals, industrial facilities, schools, hotels and infrastructure projects. NICEIC-approved engineers, grooveless Powerball technology, up to 25 metres per minute. Full BS 7671 certification on every installation. Call 0117 463 2988.
The Double-S system replaces manual effort with precision mechanical pulling — reducing installation time, eliminating cable damage, and giving every project a consistent, certifiable outcome.
TFP engineers survey all cable routes — ducting, ladder containment, cable trays, raised-floor voids and underground runs — then configure the correct Double-S puller model and spacing for each specific route.
Pullers are positioned at calculated intervals through the containment system. The grooveless Powerball design prevents cable jacket abrasion during installation and extended hold periods — eliminating a key failure point of conventional methods.
Up to 40 pullers per inverter operate simultaneously at adjustable speeds up to 25 metres per minute. Dual-motor drive provides consistent tension throughout, eliminating the force spikes that damage cables during manual pulling.
All installations are tested to BS 7671 by our NICEIC-approved engineers. Full certification, EICR reports and test documentation are provided at handover — ready for client compliance records, building control or sector-specific audit requirements.
Double-S Powerball operation — spacing control across cable containment
Every feature of the Double-S system addresses a specific failure point of conventional cable installation — from cable damage and installation speed to worker safety and project documentation.
Eliminates jacket abrasion and cable damage during installation and hold periods — the most common cause of cable degradation in traditional pulling.
Sustained mechanical pulling at speeds that are physically impossible to maintain manually — dramatically shortening programme time on large installations.
Networked puller operation means a single power panel can coordinate an entire cable run simultaneously — no sequential manual repositioning required.
Each Double-S puller uses two motors rather than one — delivering superior pulling strength, better stability and sustained performance on demanding runs.
A detailed scale display replaces colour-coded gauges — giving both experienced engineers and new operators clear, accurate read-outs throughout the pull.
Ball spacing is easily adjusted with a standard spanner — allowing rapid reconfiguration between different cable types and containment geometries on the same project.
Mechanical assistance significantly reduces musculoskeletal strain on installation teams — lowering injury risk, reducing fatigue and supporting your site's health and safety compliance.
The HM-180 model mounts directly to cable tray side rails — making it ideal for overhead containment installations without additional fixings, brackets or access equipment.
The Double-S range spans compact LV cable installations through to high-power HV infrastructure runs. TFP will specify the correct model — or combination of models — for your project's exact requirements.
Lightweight and compact — 34% lighter than the original model. Ideal for LV and data cabling through tight containment, raised-floor voids and congested routes.
High-tension chain model with tray-side-rail mounting capability. No separate tension adjustment — built for continuous, high-demand MV and LV distribution runs.
Improved size and usability profile — the most versatile model in the range. Dual 150W motors with spanner-adjustable ball spacing for wide-ranging commercial applications.
Dual 150W motors with spanner-adjusted ball spacing — designed for high-volume cable installation programmes on large commercial builds and infrastructure projects.
The highest-power model in the Double-S range. Dual 200W motors deliver the pulling force required for heavy HV cable on the most demanding infrastructure installations.
The Double-S Power Panel manages the full puller network — delivering co-ordinated, consistent pulling across up to 40 units per inverter on a single cable route.
The Double-S system performs wherever large-scale or complex cable runs are required — from dense data hall containment to long underground duct routes on infrastructure sites. TFP has sector-specific experience across the full range of UK commercial and public-sector environments.

Discuss your projectManual cable pulling was designed for a different era of electrical installation. The Double-S system addresses every limitation — speed, safety, consistency and documentation — that manual methods cannot.
| Feature | Traditional Manual Pulling | Double-S Smart Cable Pulling |
|---|---|---|
| Installation method | Manual force — multiple operatives per run | Controlled mechanical pulling at adjustable speed |
| Cable jacket damage risk | High — friction, uneven tension at bends | Minimal — grooveless Powerball eliminates contact points |
| Pull speed on long runs | Limited by manual capacity and fatigue | Up to 25 metres per minute, sustained |
| Labour requirements | Large team — high cost, high coordination | Reduced headcount, lower fatigue, fewer incidents |
| Manual handling risk | Significant — confined spaces, heavy drums | Greatly reduced — mechanical assistance throughout |
| Installation consistency | Variable — depends on team technique and fatigue | Consistent tension and quality across every run |
| Suitable for HV cable | Difficult and high-risk at scale | HM-230 dual 200W motors — built for HV runs |
| Raised floor / overhead routing | Difficult — limited access and visibility | Optimised — tray-rail mounting on HM-180 |
| Project scale suitability | Small installations only | Large commercial, industrial & infrastructure |
Whether you are an M&E project manager, facilities manager, main contractor or building owner — the Double-S system delivers measurable improvements across the critical areas of any cable installation programme.
Mechanical pulling at up to 25 metres per minute means large cable volumes are installed in a fraction of the time compared to manual methods — protecting your commissioning programme and handover dates.
The grooveless Powerball design maintains cable integrity throughout the full run, including extended hold periods. No jacket abrasion, no tension spikes — essential for high-specification power and data cabling.
Every TFP installation is carried out by NICEIC-approved engineers and certificated to BS 7671. Full EICRs, test certificates and installation records provided — ready for building control, client audit or sector compliance frameworks.
Mechanical assistance reduces musculoskeletal strain and incident risk on every run. Fewer operatives required in confined spaces — directly improving your site's safety record and CDM compliance position.
