ECOCABLES Thunderbolt Cable Solutions
When cables operate at full load, they generate a tremendous amount of heat. ECOCABLES uses heavy-gauge OFC up to 20 AWG as the power core, which features extremely low DC resistance. Even when the cable is continuously powered at the full load of 240W EPR, the internal temperature rise can be controlled within ≤ 30°C. With a top-tier UL94-V0 rated flame-retardant housing, it ensures safety of the whole-house data center.
Ordinary wires are highly prone to causing flickering of the central control screen and packet loss under complex interference. ECOCABLES Thunderbolt cable features a 360° EMI shielding matrix constructed from high-density tinned copper braid and aluminum foil, which completely isolates kitchen EMI and ensures lossless 8K video transmission.
Bathroom environments feature extremely high humidity and water vapor, and the internal space of smart mirrors is extremely confined. ECOCABLES provides customized 90° right-angle connector molds that perfectly fit the narrow space behind the mirror; the interior of the connector adopts 24K thick gold-plated terminals paired with a 360° fully sealed tinplate internal shield, and the outer layer is wrapped with a moisture-proof TPE jacket, achieving excellent oxidation resistance and moisture-proof performance.
Air purifiers, fresh air systems, and environmental monitoring equipment need to simultaneously process multiple data sources such as PM2.5/VOC sensors, cloud synchronization, and high-definition displays. Ecocables utilizes a high-speed Thunderbolt cable architecture, combined with shielding and a high-temperature-resistant TPE sheath. It enables real-time data transmission, smooth display, and efficient cloud synchronization, concurrently improving EMI resistance and advancing the device’s level of intelligence.
