Why Choose Pure Copper Lug Cable?
- 99.9% Pure Copper — Lower resistance than CCA (copper-clad aluminum); less heat and voltage drop
- Factory Crimped Terminal — Hydraulic crimp ensures gas-tight connection; no corrosion at joint
- Flexible Stranded Wire — Easy routing in tight spaces; resistant to vibration fatigue
- Ring Terminal — Secure bolt-on connection; will not pull out under vibration
- PVC/Silicone Insulation — Oil, UV, and abrasion resistant for automotive and outdoor use
Typical Applications
- 12V/24V battery bank interconnect cables
- Solar panel to charge controller wiring
- Inverter to battery positive/negative cables
- Vehicle chassis grounding strap
- UPS and backup power system wiring
- Marine and RV electrical system wiring
FAQ
Q: What is the difference between pure copper and CCA (copper-clad aluminum) cable?
A: Pure copper has ~60% lower resistance than CCA at the same cross-section. CCA cables run hotter, have higher voltage drop, and are not suitable for high-current applications. Always use pure copper for battery and inverter connections.
Q: What terminal hole size do I need?
A: Match the terminal hole to your bolt size. M6 (6mm bolt) for most battery terminals and bus bars; M8 (8mm bolt) for larger inverter terminals. Check your equipment specifications before ordering.
