Core Innovations
1. Pressure Technolog
- Interlocked steel clamps with tin-plated copper alloy ensure uniform pressure distribution across 150mm² conductors
- Self-adapting contact jaws eliminate cold flow deformation (tested to 500+ thermal cycles)
2. Advanced Thermal Management
- Integrated cooling fins increase heat dissipation by 40% vs standard designs
- Silver-nickel plating maintains <0.2mΩ resistance at 300A continuous load
3. Seismic Resilience
- Anti-shock system: Spring-loaded tension control prevents screw loosening
- Corrosion-proof hardware: M10 stainless steel screws with DIN7984 threadform
4. Smart Connectivity
- Tool-free busbar integration: Central 10mm slots accept up to 10x6mm copper bars
- Phase-segregated design: 8mm inter-pole distance with dual insulation barriers
