Dongfeng KL truck parts controller and communication interface Shielded wire assembly 7915070-C3300

Built as the backbone of the truck’s communication network, this shielded wire assembly features industry-leading anti-interference design. It adopts a dual-layer shielding structure: an inner 95% tinned copper braid and an outer aluminum foil wrap, which together block 98% of electromagnetic interference (EMI) and radio frequency interference (RFI) from the engine, alternator, and 4G/GPS systems. The shielding effectiveness reaches ≥85dB at 1GHz, ensuring stable CAN FD signal transmission with a data rate of up to 5Mbps—critical for real-time communication between controllers. A drain wire (tinned copper) grounds the shielding, diverting interference to the cab frame and preventing signal distortion that causes control system malfunctions (repair costs up to $1,200)

Engineered for long-term reliability in harsh truck environments, the 7915070-C3300 assembly uses premium insulation and conductor materials. The conductors are made of oxygen-free copper (OFC) with 7×0.25mm strands, offering low resistance (≤0.05Ω/m) and high tensile strength (150MPa), resisting breakage from cab vibration. The insulation is cross-linked polyethylene (XLPE) with a 0.8mm thickness, achieving a temperature rating of -40℃ to 125℃—adapting to extreme cold and heat from adjacent engine components. The XLPE insulation is also oil-resistant (resisting diesel and transmission fluid) and abrasion-resistant (passing 10,000-cycle rubbing testing), preventing insulation damage that leads to short circuits

Optimized to endure the dynamic and harsh conditions of truck operation, the assembly integrates weatherproof and vibration-resistant features. The multi-pin connectors (AMP 1-967648-1) feature HNBR rubber seals, achieving IP67 protection—resisting water ingress and dust accumulation in engine bays or under-dash areas. The wire loom is wrapped in a flexible nylon braid that absorbs vibration (10-500Hz) from the truck’s chassis, preventing the wires from rubbing against metal components and causing wear. A strain relief boot at each connector end reinforces the wire-conductor junction, resisting pulling forces (up to 50N) that could disconnect the interface. 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 and color-coded connectors (compliant with DIN 47100) allow a single technician to complete replacement in 60 minutes—no specialized crimping or testing tools needed, as it auto-syncs with the truck’s CAN network. The OE-compatible design eliminates compatibility issues common with aftermarket wires, which often cause controller errors or communication failures. By ensuring stable signal transmission, it extends the service life of electronic components (ECU/TCU) by 30% and reduces diagnostic time for electrical issues (costing $150/hour). Backed by a 2-year/200,000km Dongfeng warranty, it provides predictable maintenance expenses and enhances the reliability of the truck’s electronic control system
