1. LOW VOLTAGE AUTOMOTIVE WIRE: Low-voltage wiring is a flexible wire with stranding conductors and insulated sheathing that carries 60 volt or less of electricity. The heavy duty gauge wires are mostly used on hybrid and electric vehicle systems. 2. COPPER CLAD ALUMINUM CORE: CCA is made by bonding layers of copper onto aluminum core, it allows a weight and cost-saving benefits regarding copper cable. Copper clad aluminum conductor can completely meet the requirements of power transmission. 3. DURABLE & FLEXIBLE PVC PROTECTION: As the most common insulation material, PVC is tough to endure harsh conditions with great resistance to oil, chemical, grease and flame. The smooth surface is ideal for pulling through wire loom or other wiring management. 4. HEAVY DUTY COPPER LUG CONNECTORS: SC cable lug is coated with tin for corrosion resistance. The seamless tubular barrel and high conductivity copper contacts provide consistent high performance for reliable power application. 5. ALL ACCESSORIES IN ONE PACKAGE: The wire kit would be a good helper for wiring circuits, battery grounds and alternators of automotive battery system. You will receive 1pc 2FT black wire of 2 GAUGE. 2pcs M8 and 2pcs M10 size of SC lugs. battery welding cable
