TEMI5654 is made of a mixture of polyester monofilament and tin plated copper foil wire. The overall structure is mainly composed of tin-plated copper foil wire. The weight of the tin-plated copper foil wire is half that of the tin-plated copper wire, effectively reducing the weight while also having excellent electromagnetic shielding function. The side opening structure is easy to install and maintain.
The Tinned Copper Foil Self-closing Wrap-TEMI5654 is an electromagnetic interference (EMI) shielding sleeve engineered for wire harness protection in automotive, rail transit, aerospace, and industrial automation applications. Constructed from polyester monofilament and tin-plated copper foil strands, TEMI5654 delivers greater than 60 dB shielding effectiveness from 30 MHz to 3 GHz, tested per GB/T 30142. The side-opening self-closing design allows installation around an assembled harness without threading tools or secondary tape. Operating from -50°C to 150°C and meeting UL94 V-0 flame retardancy requirements, the Tinned Copper Foil Self-closing Wrap-TEMI5654 is suitable for demanding harness shielding requirements across automotive and industrial sectors. The tin-plated copper foil strands weigh approximately half as much as equivalent tin-plated solid copper wire, making this product relevant for new energy vehicle programs where cumulative harness weight is actively managed.
The Tinned Copper Foil Self-closing Wrap-TEMI5654 achieves shielding effectiveness greater than 60 dB across 30 MHz to 3 GHz per GB/T 30142, sufficient to attenuate high-frequency interference generated by motor controllers, power inverters, and onboard communication modules in new energy vehicles and industrial automation systems. The -50°C to 150°C operating range covers engine compartment thermal conditions and outdoor installation environments including photovoltaic arrays and EV charging enclosures. Low-temperature performance is a qualification step that procurement teams occasionally overlook during warm-season product approval — for cold-climate assembly environments or outdoor harness deployment, verifying flexibility at the rated lower temperature limit before finalizing material approval prevents field issues later. The UL94 V-0 flame retardancy rating of the Tinned Copper Foil Self-closing Wrap-TEMI5654 is integral to its material formulation rather than applied as a surface coating, ensuring stable flame resistance throughout the product service life even after thermal cycling.

Values listed are typical test results measured under standard laboratory conditions. For specific product test reports, consult your sales representative. Performance in final application depends on installation method, overlap ratio maintained, and ambient operating conditions.
The Tinned Copper Foil Self-closing Wrap-TEMI5654 is specified for EMI shielding of high-voltage wire harnesses in new energy vehicles, including battery-to-inverter power cables, motor drive harnesses, and ADAS sensor wiring. New energy vehicle high-voltage architectures impose shielding requirements that conventional low-voltage harness protection materials may not reliably meet. TEMI5654 addresses both the electromagnetic shielding requirement (greater than 60 dB) and the flame safety specification (UL94 V-0) within a single material. For engine compartment harnesses and ECU/VCU signal wiring, the -50°C to 150°C temperature rating provides the necessary thermal margin. Effective harness shielding in automotive programs requires evaluating the full system, including connector grounding continuity, routing path geometry, and the overlap ratio maintained during installation — the wrap performance is one component of the overall EMC design, and the total shielding effectiveness depends on how all these elements work together.
TEMI5654 is used for harness EMI protection in rail transit vehicles including high-speed rail, metro, and light rail systems; aerospace equipment; photovoltaic inverters; EV charging stations; and industrial automation systems including PLC control panels, variable frequency drives, and servo motor wiring. In these installations, engineers often specify multiple complementary harness protection products. Ptfe heat shrink tubing and solder sleeves are commonly used for localized terminal insulation and splice protection alongside a dedicated EMI shielding wrap for continuous harness coverage. The Tinned Copper Foil Self-closing Wrap-TEMI5654 provides broadband electromagnetic shielding across the full harness run, while ptfe heat shrink tubing and solder sleeves address individual termination points. For small-gauge harness segments where heat shrink 3 16 inch products provide mechanical and thermal protection at terminations, the Tinned Copper Foil Self-closing Wrap-TEMI5654 delivers the required EMI attenuation for the harness body between those points.

Nine standard sizes from Φ8 mm to Φ50 mm cover harness outer diameters from 5 mm to 60 mm. Custom fixed-length cutting and non-standard sizes are available upon request; confirm customization lead times with your sales representative during the project specification phase.
The Tinned Copper Foil Self-closing Wrap-TEMI5654 is manufactured at a facility certified to ISO 9001, IATF 16949, ISO 14001, ISO 45001, and the military quality standard GJB9001C. For automotive procurement teams qualifying suppliers to OEM program requirements, IATF 16949 certification signals alignment with automotive quality management system expectations and supports standard supplier audit documentation requirements. The full certification portfolio is relevant for Tier 1 harness manufacturers and OEM-directed supply chains where documented quality credentials are a prerequisite for supplier approval. Complete product technical documentation, including product specifications and test report references, is available to support internal technical evaluations and supplier qualification submission packages. When installing the Tinned Copper Foil Self-closing Wrap-TEMI5654, maintaining the minimum 30% overlap specification is required to achieve the rated shielding effectiveness; this installation parameter should be captured in harness assembly work instructions to ensure consistent shielding performance across production units.
