Panduit SE125P-TR0 1.25" Rail-Compliant Braided Sleeving

Panduit SE125P-TR0 Braided Expandable Sleeving

The Panduit SE125P-TR0 delivers 200 feet of continuous 1.25" PET braided sleeving engineered for installations where abrasion resistance, thermal performance, and regulatory compliance intersect. Certified to U.S. and European passenger rail standards (EN 45545-2, NFPA 130), this sleeving is specified for transit-system cable runs, industrial automation harnesses, and data-center hot-aisle routing where bundled cables face mechanical stress, temperature swings, and audit scrutiny. The 200-foot bulk roll eliminates mid-run splices on full railcar deployments or multi-rack backbone runs, and the open-weave PET construction maintains airflow around high-density bundles without trapping heat or condensation.

Key Features

• 200 ft (61 m) continuous length eliminates splices on long runs
• Compliant with U.S. and European passenger rail fire/smoke standards (EN 45545-2, NFPA 130)
• -94°F to 257°F (-70°C to 125°C) operating range for outdoor enclosures, engine compartments, and thermal zones
• Open-weave PET construction allows heat dissipation and moisture escape
• Expandable 1.25" nominal diameter accommodates irregular bundle shapes and mid-run breakouts
• Lightweight, flexible design conforms to tight bend radii without kinking
• CSA Certified, UL Recognized (E116868), RoHS compliant
• Black finish for professional appearance in visible cable trays

Polyethylene Terephthalate (PET) monofilament resists edge cuts, continuous flexing, and UV degradation better than nylon alternatives, making the SE125P-TR0 the go-to choice for outdoor camera runs along building perimeters, underfloor data-center plenum bundles, and industrial robot-arm cable carriers. The open diamond weave expands from 0.94" to 1.88" (24 mm to 48 mm), letting you sleeve pre-terminated cables or breakout individual conductors mid-run without cutting the sleeve. That elasticity also absorbs bundle movement — critical in railway applications where vibration and thermal cycling stress fixed cable ties. At 257°F continuous, this sleeving handles power-supply exhaust zones, rooftop conduit in desert climates, and equipment racks where backup generators or UPS banks elevate ambient temps beyond typical wire-loom limits. The -94°F low end covers unheated telecom shelters, refrigerated warehouses, and cold-storage camera installs where PVC and polyolefin sleeves turn brittle.

The 200-foot roll matches the cable-pull length on a standard passenger railcar (typically 85–180 feet per car side) or a raised-floor data-center row (150–200 feet), eliminating the labor and failure points of sleeving splices. For transit integrators, rail compliance is non-negotiable: EN 45545-2 HL3 and NFPA 130 restrict flame spread and smoke density in occupied spaces, and non-certified sleeving triggers inspection failures during commissioning. Data-center and industrial buyers use the SE125P-TR0 to group mixed-signal bundles (PTZ control + PoE + fiber) in a single abrasion-resistant sheath that won't chafe insulation when pulled through cable tray knock-outs or J-hooks. The black finish hides dust accumulation in high-traffic areas and maintains a clean look in open-ceiling warehouses or corporate lobbies where cabling is visible. Installation is faster than split loom: push the bundle through the sleeving (or expand the weave over connectors), secure with Panduit or Thomas & Betts cable ties every 3–4 feet, and the open weave locks in place without additional fasteners. For mid-run branches, spread the weave, route the breakout cable, and the braid self-closes around the remaining bundle.

Passenger-rail and mass-transit projects require material certifications at bid time, and the SE125P-TR0's UL Recognition (E116868) and CSA mark satisfy North American AHJ requirements alongside the European rail standards. The 200-foot package quantity (one roll per package, two rolls per carton) is bulk-sized for contractors handling multi-car train retrofits, airport terminal access-control installations, or stadium camera networks where a single PO covers the full job. For industrial panels and automation cabinets, the 1.25" diameter bundles six to eight 18 AWG control cables or four shielded Cat6 runs, keeping harnesses organized inside enclosures and protecting against sharp panel edges during maintenance. When you're quoting a rail project, a refinery CCTV system, or a 100-rack data center, the SE125P-TR0 is the certified, bulk-length sleeving that passes inspection, handles the environment, and ships on the same Panduit PO as your cable ties, terminal blocks, and grounding hardware.
