Panduit SE25TC-C Pan-Wrap™ Tinned Copper Braided Sleeving

The Panduit SE25TC-C delivers electro-plated tin copper braided protection for cables and wire bundles in security, data center, and industrial installations where electromagnetic interference, radio frequency interference, or electrostatic discharge pose reliability risks. This 0.25-inch nominal inside diameter sleeving handles 25-amp continuous current loads while conforming to CID A-A-59569 (formerly MIL-SPEC QQB-575), making it suitable for power distribution, signal integrity applications, and environments requiring documented compliance. Each 100-foot reel provides expandable coverage that accommodates irregular bundle shapes and mid-run branch-offs without cutting or splicing.

Key Features

• Tinned copper braid provides EMI, RFI, and ESD shielding for sensitive cable runs
• 25-amp continuous current capacity supports power distribution and high-current signal applications
• 0.25-inch (6.35 mm) nominal inside diameter fits common security and data cabling
• Expandable braid construction allows installation over connectors and accommodates bundle diameter variations
• Tin-plated finish prevents corrosion in humid or chemically active environments
• Conforms to CID A-A-59569 (formerly MIL-SPEC QQB-575) for government and military installations
• 100-foot (30.5 m) reel length reduces waste and minimizes mid-run splices
• Continuous abrasion resistance protects against cable jacket wear in high-vibration or cable-tray environments

Tinned copper braided sleeving addresses three distinct failure modes in commercial security and industrial control installations: electromagnetic interference that corrupts analog video or RS-485 data signals, physical abrasion where cables pass through sharp-edged openings or vibrate against metal surfaces, and electrostatic discharge in low-humidity server rooms or manufacturing floors. The SE25TC-C's electro-plated tin copper construction provides a continuous grounded shield path when properly bonded at both termination points, shunting induced currents to ground rather than allowing them to couple into signal conductors. The braid's flexibility and expandability allow it to conform to irregular bundle cross-sections—common when mixing PoE network cables with coaxial video runs or fiber—without creating pressure points that damage cable jackets over time. Installers working with pre-terminated cables benefit from the sleeving's ability to expand up to 150% of its nominal diameter during installation, then contract to grip the bundle firmly once connectors pass through.

The 25-amp continuous current rating makes the SE25TC-C appropriate for low-voltage power distribution in access control or intercom systems where multiple door strikes, mag locks, or powered endpoints share a common trunk line. In these deployments, braided sleeving serves dual purposes: it provides mechanical abrasion protection where bundles pass through wall penetrations or conduit transitions, and it acts as an equipotential bonding conductor between enclosures to prevent ground loops. Security integrators working in industrial facilities—warehouses with overhead cranes, manufacturing plants with VFD-driven motors, or outdoor sites near high-voltage transmission lines—use tinned copper sleeving to protect IP camera networks from radiated interference that manifests as periodic frame loss, corrupted RTSP streams, or Ethernet link flapping. The tin plating extends service life in coastal or chemical-exposure environments by preventing copper oxidation that degrades shielding effectiveness and increases contact resistance at termination points.

Compliance with CID A-A-59569 (the current designation for the legacy MIL-SPEC QQB-575 standard) documents the sleeving's material composition, braid coverage percentage, tensile strength, and current-carrying capacity through third-party testing. Government and military security installations—federal buildings, courthouses, defense facilities—require this documentation during final inspection and commissioning. The 100-foot reel length aligns with typical cable-pull distances in commercial buildings while reducing packaging waste and the number of mid-run terminations that introduce impedance discontinuities in shielded systems. Integrators can cut to length in the field, applying heat-shrink terminations or conductive tape at cut ends to prevent fraying and maintain shield continuity through connectors or enclosure entry points.
