Hybrid Power Cable – Integrated Power & Signal Transmission Core

Description

The Hybrid Power Cable (Part No. 4493702820) is a critical component in semi-trailer brake systems, integrating power supply and signal transmission for ABS/EBS systems. Its dual-layer shielding (aluminum foil + tinned copper braid) resists electromagnetic interference (EMI) and voltage fluctuations, ensuring stable power delivery to ECUs, sensors, and valves, while synchronizing wheel speed data. The cable features high-purity copper conductors with XLPE insulation (-55℃ to 150℃) and flame-retardant PVC sheathing, suitable for high-temperature, vibration, and humid environments.

Core Functions:

1. ​Power Delivery: Supplies 12V/24V DC power to ABS/EBS modules.
2. ​Signal Integrity: Embedded data lines transmit real-time sensor signals to ECUs for precise braking control.
3. ​EMI Resistance: Dual shielding prevents interference from onboard electronics (e.g., GPS, radios).

Key Importance:

• ​System Integration: Reduces cable clutter and simplifies troubleshooting.
• ​Safety Redundancy: Dual-channel design ensures backup for power/signal transmission.
• ​Durability: IP67 connectors and corrosion-resistant terminals enhance longevity in harsh conditions.

Replacement Guidelines:

1. ​Compatibility Check: Match pin configurations and connector types (e.g., Deutsch DT, AMP Superseal).
2. ​Shielding Grounding: Secure shield layers to chassis ground to prevent EMI.
3. ​Bending Limits: Maintain a minimum bend radius ≥5× cable diameter to avoid damage.
4. ​Heat Avoidance: Route away from exhaust systems to prevent thermal degradation.
