Product Highlights
Conductive Material & Current-Carrying Performance
Conductive arms employ slot-shaped aluminum alloy profiles (high conductivity, high strength) with anodized surface treatment. Combines corrosion resistance, high mechanical strength, and excellent heat dissipation.
Novel Contact Structure
Self-energized contact fingers utilize chrome bronze alloy’s inherent elasticity to clamp the contact blade. Beyond meeting standard current-carrying requirements, it satisfies short-term thermal load and electromagnetic force under short-circuit faults while offering superior mechanical wear resistance.
Fixed Connections
Monolithic cast bearing housing with linkage mechanism design. Internal combined-support bearing structure enables lightweight operation.
Maintenance-Free Transmission System
Transmission system designed per maintenance-free requirements. Self-lubricating bushings paired with stainless steel pins prevent binding issues in rotating components.
