Product Highlights
Premium Conductive Material
Current-carrying arms employ rectangular aluminum alloy profiles featuring high strength, lightweight construction, enhanced heat dissipation area, and superior corrosion resistance.
Novel Contact Structure
Self-energized contact fingers utilize chrome bronze alloy’s inherent elasticity to clamp the contact blade. Beyond standard current-carrying requirements, withstands short-term thermal load and electromagnetic force during short-circuit faults while exhibiting excellent mechanical wear resistance.
Fixed Connections
Conductive path employs permanent connections (excluding moving/stator contact engagement) to achieve maintenance-free functionality.
