2026年6月26日High Voltage Product Product Center 770

Available Certifications CE / UL Availability depends on model and configuration.

Overview

Medium Voltage Metal-Clad Switchgear / MCSG is designed for safe and reliable power distribution in utility, industrial, commercial, and infrastructure projects. With a withdrawable VCB, compartmentalized metal-clad structure, insulated busbar system, mechanical interlocks, and optional arc-resistant design, it provides stable operation for medium-voltage power systems.

Product Advantages

Metal-Clad Compartmentalized StructureThe switchgear adopts a metal-clad structure with independent functional compartments.

Withdrawable Vacuum Circuit BreakerThe withdrawable VCB design allows the breaker to be moved safely between connected, test, and disconnected positions.

Enhanced Safety Interlocking SystemMechanical interlocks are designed to ensure the correct operating sequence under normal working conditions.

Optional Arc-Resistant DesignFor critical applications, the MCSG can be designed with arc-resistant features.
