TEMI5655 is made of a mixture of tin-plated copper wire, polyester monofilament and tin-plated copper foil wire, which has the function of excellent shielding electromagnetic interference. The side opening structure is easy to install and maintain.
The Tinned Copper Self-closing Wrap-TEMI5655 is an electromagnetic interference shielding wrap engineered for wire harness protection in automotive, rail transit, aerospace, and industrial electrical environments. Constructed from a precision braid of tin-plated copper wire, polyester monofilament, and tin-plated copper foil wire, the Tinned Copper Self-closing Wrap-TEMI5655 delivers measured shielding effectiveness exceeding 60 dB across the 30 MHz to 3 GHz frequency range, tested in accordance with GB/T 30142. This material combination provides both the conductive shielding path from the tin-plated copper and the mechanical durability contribution of the polyester monofilament.
The product incorporates a side-open self-closing structure that opens and closes without tools, enabling installation on existing harness bundles without threading terminals or connectors through a closed sleeve. The self-closing design also supports field maintenance and component reuse: this wrap can be opened for service access and reapplied to the harness without replacement. Working temperature spans -50°C to 150°C, accommodating cold-start installation conditions and high-temperature underhood routing zones. Flame retardant material construction satisfies the mandatory fire safety requirements found in automotive OEM and tier-1 supply chain qualification audits.
When selecting an EMI shielding wrap for harness applications, the starting point is shielding effectiveness across the relevant frequency band — not brand reputation or packaging format. The Tinned Copper Self-closing Wrap-TEMI5655 establishes its performance baseline through a single verified test result:
| Test Item | Test Method | Test Result |
|---|---|---|
| Shielding Effectiveness (30 MHz to 3 GHz) | GB/T 30142 | 60 dB |
Shielding effectiveness of more than 60 dB attenuates electromagnetic energy by a factor exceeding one million relative to an unshielded baseline. For harnesses routed near motor inverters, power distribution units, or vehicle communication modules, this level of attenuation is sufficient to prevent sensitive signal lines from picking up conducted or radiated interference under normal operating conditions. All test values are typical figures; product-specific test reports are available from your sales representative.
The Tinned Copper Self-closing Wrap-TEMI5655 operates from -50°C to 150°C. Low-temperature performance is frequently under-specified in EMI shielding products: braided sleeve materials that perform normally at room temperature may become brittle at sub-zero installation temperatures, cracking during harness assembly and requiring costly replacement. This -50°C lower limit is validated by material design, not assumed from ambient operating conditions. At the upper end, 150°C covers most automotive underhood harness routing zones excluding direct contact with exhaust manifolds.
In automotive harness bundles, battery management system cable assemblies, and energy storage wiring, flame retardant compliance is a mandatory material requirement verified during supplier qualification. The TEMI5655 addresses this at the material formulation level, reducing the risk of late-stage compliance findings during OEM or tier-1 qualification processes.
The hybrid braid of tin-plated copper wire and polyester monofilament provides mechanical abrasion resistance at harness bend points and routing bracket contact zones. In dynamic routing environments such as door harnesses and steering column assemblies, abrasion at fixed support points progressively degrades shielding performance over time. The braided construction of this shielding wrap distributes mechanical stress across the wire-monofilament matrix rather than concentrating it at single conductor paths.
The primary application for the Tinned Copper Self-closing Wrap-TEMI5655 is EMI shielding attenuation in automotive wire harnesses, covering both conventional vehicles and new-energy electric vehicles. Harness bundles routed near motor inverters, DC-DC converters, and on-board chargers in 400V or 800V high-voltage architectures are subject to radiated and conducted interference that can affect sensors, controllers, and communication systems in the vehicle. For tier-1 harness manufacturers supplying under IATF 16949 quality systems, the product's multi-standard certifications (ISO 9001, IATF 16949, GJB9001C) support supplier qualification documentation requirements.
Traction power electronics, pantograph transients, and onboard communication systems in rail vehicles generate broadband electromagnetic interference across long harness runs. TEMI5655 is designed for EMI shielding in high-speed rail, metro, and light-rail vehicle harness applications where signal stability is a safety-critical requirement.
Avionics harnesses and industrial automation cable assemblies operate in environments with strict electromagnetic compatibility requirements. The Tinned Copper Self-closing Wrap-TEMI5655 is suitable for avionics harness EMI shielding, supported by the manufacturing site's GJB9001C military quality management certification. In industrial servo drives and communication equipment, the wrap provides EMI protection for control and signal harnesses running in electrically noisy production environments.
The Tinned Copper Self-closing Wrap-TEMI5655 is available in nine standard sizes from Ø8 mm to Ø50 mm nominal inner diameter, covering harness bundle diameters from 5 mm to 60 mm with a minimum overlap of 30%:
