Technical Specifications

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

    Lightweight operation

    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.
