Indoor Disconnector Switch/Isolator

Specs & Performance of Medium Voltage Indoor Disconnectors

As a specialized disconnector switch supplier, Liyond provides indoor isolating solutions that excel in thermal stability and mechanical endurance. Our indoor range is engineered for high-voltage environments up to 12kV, with specific configurations available for 24kV and 40.5kV systems.
To ensure seamless integration into various switchgear layouts, our units feature standardized mounting and flexible operation. Each series is designed to handle rigorous electrical loads, with core performance metrics including:

Rated Current Range: Flexible options from 400A to 4000A to support diverse industrial and utility load requirements.

Short-Circuit Reliability: Exceptional rated short-time withstand currents (up to 40kA/4s) and peak withstand currents (up to 100kA) to maintain system integrity during fault events.

Advanced Insulation Levels: High dielectric strength with power frequency withstand voltages up to 42kV (phase-to-earth) and lightning impulse withstand voltages up to 75kV (peak).

Versatile Drive Mechanisms: All units are compatible with heavy-duty manual mechanisms (such as the CS6-1 and CS6-2 series) for local control, or motorized mechanisms (such as the CX-6 II) that allow for efficient remote-controlled switching operations.

Whether you require wall-through installations, grounding types, or specific phase-to-phase distances, our indoor disconnector switch range offers the technical precision needed for critical disconnector switch infrastructure.
