Overcoming the Lightweighting Challenge in Modern Electrical Systems
As New Energy Vehicles (NEVs) and autonomous systems grow in complexity, the demand for more wiring often contradicts the goal of energy efficiency. Pure copper conductors are the primary contributors to harness weight, but traditional thinning leads to fragile connections. FISSOT® provides the ultimate solution: High-Performance CCS for high-stress signal lines and CCA Enameled Wires for weight-sensitive electrical components. Our bimetallic conductors break through the limitations of traditional copper, offering a 15%–40% reduction in weight while providing superior tensile strength and vibration resistance. At FISSOT, we don't just supply wire; we provide the strength and lightness required for the future of transportation.
Engineered Performance: Bimetallic vs. Pure Copper
| Key Property | Pure Copper (Baseline) | FISSOT® CCS | FISSOT® CCA |
|---|---|---|---|
| Weight Reduction | 0% (Base Weight) | ~10% Lighter | ~30-40% Lighter |
| Tensile Strength | ~200–250 MPa | 400–2000+ MPa | ~150–200 MPa |
| Vibration Fatigue Life | Standard | Superior | Moderate |
| Primary Automotive Application | General Power Lines | ABS Sensors, High-Stress | Motor Winding, Infotainment |
Reduce Costs Without Sacrificing Performance
Switching from solid copper to FISSOT® CCS&CCA can reduce your material costs by up to 40%.
