Automotive cable Cabletech 2Ga OD12mm CU+AL – 2 gauge, 12 mm outer diameter, copper+aluminum conductor

Cabletech 2Ga OD12mm CU+AL is an automotive power cable designed for vehicle electrical systems and high-current applications. The conductor combines copper and aluminum to provide a balance between conductivity, weight, and cost. With a 2 gauge cross-section and an approximate 12 mm outer diameter, the cable is suitable for battery and starter connections, power distribution in audio systems, and other automotive installations that require a robust flexible conductor.

Advantages

The combined copper and aluminum conductor delivers improved conductivity compared with aluminum-only cables while keeping weight and cost lower than pure-copper alternatives. The 2 gauge size ensures adequate current-carrying capacity for many automotive power tasks, and the roughly 12 mm outer diameter makes routing through engine bays and cable channels manageable. The cable’s construction provides mechanical flexibility for easier installation and tighter bends without compromising the conductor integrity.

Suitable for

• Battery-to-starter connections in passenger cars and light commercial vehicles
• Main power feeds for aftermarket car audio amplifiers and power distribution blocks
• Vehicle power harnesses where reduced weight and cost are required
• Temporary high-current connections during diagnostics or charging

Key specifications

• Conductor material: combined copper and aluminum (CU+AL)
• Conductor size: 2 gauge (2Ga)
• Approximate outer diameter: 12 mm
• Application: automotive power, battery and starter wiring, audio power distribution
• Construction: flexible multi-strand conductor designed for routing in vehicles

How to use

Measure required cable length accounting for routing and connector termination. Strip insulation according to the connector supplier’s specification, ensuring clean conductor surfaces for a reliable electrical connection. Use appropriately sized lugs or terminals rated for 2 gauge conductors and for the expected current. Securely crimp or solder terminations where specified, then insulate with heat-shrink tubing or approved automotive insulation. Route the cable away from sharp edges, moving parts, and extreme heat sources, and fasten with clamps or ties to prevent chafing and vibration damage.

Usage recommendations

For critical starter or continuous high-current circuits, verify conductor ampacity for your specific vehicle application and consider parallel runs or a pure-copper cable if lower resistance is required. Always use correct-sized terminals and proper crimping tools to ensure safe, low-resistance connections. Inspect installations periodically for signs of wear, corrosion, or loose connections.
