Dongfeng KL truck parts controller and display screen Shielded wire assembly 7915073-C3300

Built to ensure stable signal transmission between the controller and display, this assembly features a premium tri-layer shielding system. It integrates an inner 98% tinned copper braid, a middle aluminum-mylar composite foil, and an outer conductive PVC jacket, achieving ≥90dB shielding effectiveness at 1GHz—blocking electromagnetic interference (EMI) from the truck’s alternator, 4G antenna, and engine control unit. This design guarantees uncompressed LVDS video signal transmission (1920×1080 resolution, 60fps) with no flicker or color distortion, while maintaining CAN bus communication stability (data rate up to 1Mbps) for control commands (e.g., brightness adjustment, menu navigation). A dedicated ground wire diverts interference to the cab frame, preventing signal degradation that causes display freezing (repair costs up to $800)

Engineered for long-term reliability in the dynamic cab environment, the 7915073-C3300 assembly uses high-performance conductive and insulating materials. The conductors are made of oxygen-free copper (OFC) with 19×0.18mm strands, offering ultra-low resistance (≤0.035Ω/m) to ensure minimal signal loss. The insulation is thermoplastic elastomer (TPE) with a 1.0mm thickness, rated for -40℃ to 130℃ operation—adapting to extreme cold and heat from dashboard electronics. The TPE insulation is oil-resistant (resisting cleaning fluids and diesel) and abrasion-resistant (passing 15,000-cycle rubbing testing), preventing insulation cracking from contact with dashboard edges or vibration. Unlike standard PVC insulation, it remains flexible in low temperatures, avoiding wire brittleness

Optimized to withstand the harsh operating conditions of truck cabs, the assembly integrates vibration-dampening and weatherproof features. The wire harness is wrapped in a flexible EPDM foam sleeve that absorbs vibration (10-500Hz) from the truck’s chassis, preventing the wires from rubbing against metal components and causing wear. The Hirose GT13 connectors feature double O-ring seals (HNBR material), achieving IP66 protection—resisting dust ingress and water splashes from dashboard cleaning or condensation. A strain relief boot at each connector end reinforces the wire-conductor junction, withstanding pulling forces up to 80N to prevent accidental disconnection. These features ensure reliable performance in off-road, construction, and long-haul scenarios

This shielded wire assembly is designed for efficient installation and long-term cost savings for Dongfeng KL operators. The pre-labeled wires (compliant with IEC 60446) and color-coded connectors allow a single technician to complete replacement in 45 minutes—no specialized crimping or soldering tools needed, as it auto-syncs with the controller and display. The OE-compatible design eliminates compatibility issues common with aftermarket wires, which often cause display artifacts or control failures (diagnostic costs up to $200/hour). By ensuring stable signal transmission, it extends the service life of the display and controller by 40%, reducing replacement frequency. Backed by a 2-year/250,000km Dongfeng warranty, it provides predictable maintenance expenses and enhances the reliability of the truck’s infotainment and control system
