Panduit SE150TC-L Pan-Wrap Braided Expandable Sleeving

Panduit's SE150TC-L Pan-Wrap braided sleeving provides military-grade EMI, RFI, and ESD protection for cable runs in commercial surveillance, datacenter, and industrial control installations. The 1.5-inch nominal diameter handles mid-sized cable bundles while maintaining 25-amp current capacity for effective grounding and bonding. Tinned copper braid construction delivers continuous abrasion resistance and corrosion protection in harsh environments. Conforms to MIL-SPEC AA-59569 (formerly QQ-B-575) for installations requiring documented shielding performance. Supplied on a 50-foot reel—practical for trunk-line runs between equipment racks, outdoor conduit transitions, or panel-to-panel interconnects where mechanical protection and electromagnetic compliance intersect.

Key Features

• 1.5" (38.1mm) nominal inside diameter accommodates mid-sized cable bundles

• Expandable construction fits varying bundle diameters
• MIL-SPEC AA-59569 (CID A-A-59569) compliance for defense and aerospace applications
• 50-foot reel length covers typical trunk-line runs
• Silver tin-plated finish resists corrosion in outdoor or industrial environments
• Continuous abrasion protection for cables in high-friction environments

The SE150TC-L uses electro-plated tinned copper strands woven in a flexible, expandable braid. Tinning the copper accomplishes three critical objectives: it prevents oxidation in humid or coastal environments where bare copper would corrode; it maintains consistent grounding conductivity over decades of service; and it reduces insertion force when threading cables through the sleeving. The 1.5-inch nominal diameter expands to accommodate irregular bundle cross-sections or mid-run splices, then contracts to maintain firm contact—critical for both abrasion resistance and electromagnetic coupling to the outer shield. At 25 amps, this sleeving serves double duty: it's a mechanical protector and a current-carrying ground path, eliminating the need for separate bonding straps in many panel-to-panel or rack-to-rack installations. The braid density and strand gauge meet MIL-SPEC AA-59569 requirements for shielding effectiveness, typically exceeding 80 dB attenuation across the 10 MHz to 1 GHz band—sufficient to suppress RF interference from switching power supplies, motor drives, or nearby transmitters.

Commercial integrators deploy the SE150TC-L in three primary scenarios: outdoor conduit exits where cables transition from rigid metal to flexible service loops (the sleeving prevents jacket wear against conduit threads and provides grounding continuity if the conduit bond is interrupted); datacenter hot-aisle cable runs where bundled copper and fiber pass near high-current PDUs or UPS batteries (the tinned copper braid diverts induced currents and shields signal pairs from magnetic coupling); and control-panel interconnects in manufacturing or building-automation installs where cables route through cable trays shared with VFD motor leads or contactor wiring (the braid attenuates radiated emissions that would otherwise couple into low-voltage control circuits). The 50-foot reel is a practical midpoint—long enough for a typical inter-rack trunk without excess waste, short enough to handle without a dispenser cart. Installers cut to length in the field; the braid remains stable without heat-shrink termination, though many add ferrules or solder the ends when aesthetic finish or repeated handling is expected.

MIL-SPEC AA-59569 conformance ensures the SE150TC-L meets U.S. Department of Defense requirements for cable shielding in airborne, shipboard, and ground-vehicle applications—a compliance baseline that commercial datacenter operators and critical-infrastructure integrators adopt for procurement consistency and performance assurance. The specification mandates minimum braid coverage, strand tensile strength, and dimensional stability under temperature cycling, eliminating the guesswork in product selection. For surveillance integrators routing PoE trunk cables near high-power lighting circuits or HVAC contactors, the SE150TC-L provides a tested, documented solution to radiated-immunity failures that would otherwise surface as intermittent camera dropouts or corrupted video frames during motor starts. Panduit's 50-foot reel packaging simplifies job-site logistics—one reel covers a typical IDF-to-MDF run with minimal surplus, and the electro-tinned finish ensures the sleeving remains serviceable through decades of thermal cycling and humidity exposure without the green oxidation that renders bare copper braids non-conductive over time.
