High-voltage disconnector GW5

center breakIEC

GW5 Series product is a V-type rotary outdoor high-voltage disconnector. Rated voltage covers 40.5-145kV. Conductive material & current-carrying performance Novel contact structure Fully sealed bearing housing Maintenance-free transmission 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.
