Features
-
01
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. Supports maximum rated current of 4000A with short-time withstand current up to 50kA.
-
02
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.
-
03
Fully sealed bearing housing
Monolithic cast bearing housing with linkage mechanism design. Internal combined-support bearing structure enables lightweight operation.
-
04
Maintenance-free transmission
Transmission system designed per maintenance-free requirements. Self-lubricating bushings paired with stainless steel pins prevent binding issues in rotating components.
