Outdoor Disconnect Switch

Specs & Reliability of High Voltage Outdoor Disconnectors

To ensure the operational stability of power grids, our outdoor disconnector portfolio—represented by the GW1 and GW4 series, among others—is built to exceed performance expectations in open-air environments. This specialized range offers technical precision for infrastructures spanning from 12kV distribution networks up to 126kV transmission-grade switchyards.

By focusing on mechanical durability and high-dielectric strength, we provide solutions that remain resilient against environmental stressors such as high wind pressure and ice coverage. Our technical benchmarks for the disconnector switch supplier market include:

Extended Power Capacity: Engineered for voltage levels including 12kV, 40.5kV, 72.5kV, and 126kV, accommodating continuous rated currents from 200A up to 2000A.

High-Voltage Insulation: Designed with superior dielectric security, featuring power frequency withstand voltages up to 230kV and lightning impulse peak withstand levels up to 450kV for high-voltage applications.

Dynamic Fault Resilience: High-capacity performance with rated short-time withstand currents up to 25kA (4s) and peak withstand ratings of 63kA to maintain grid integrity.

Adaptive Drive Mechanisms: Fully compatible with manual mechanisms (such as the CS11, CS14, and CS17 series) for localized tactical control, or motorized mechanisms (such as the CJ2 and CJ6 series) for efficient remote switching operations.

Our high voltage outdoor disconnector switch series is the ideal choice for both greenfield substation construction and the strategic upgrade of aging disconnector switch units.
