12m Power Cable – Core Electrical Link for Semi-Trailer Brake Systems

Description

The 12m Power Cable (Part No. 4491301200) is a critical power supply line for ABS/EBS modules in semi-trailer brake systems, designed for long-distance power transmission to ensure stable electricity delivery to ECUs, sensors, and valves. Featuring high-conductivity copper cores and double-layer insulation, it resists abrasion, high temperatures (-40℃ to 125℃), and electromagnetic interference (EMI), making it ideal for harsh vehicle environments. Standardized connectors and waterproofing prevent moisture/ vibration-induced failures, ensuring 24/7 reliability.

Key Importance:

• ​Power Reliability: Directly powers ABS/EBS systems; power loss may cause brake failure or signal loss, endangering safety.
• ​Durability: Specialized materials and structure reduce aging-related failures.
• ​Compatibility: ISO 7638-compliant plugs ensure seamless integration with commercial vehicle interfaces.

Replacement Guidelines:

1. ​Length Precision: Use OEM 12m cables to avoid voltage drops or tangling.
2. ​Connector Inspection: Clean terminals and check seals before installation to prevent shorts or water ingress.
3. ​Routing Compliance: Secure along chassis brackets, avoiding heat sources and moving parts to prevent damage.
