Medium Voltage Switchboard Overview
Medium Voltage Switchboard up to 33kV supports structured distribution and protection duties in utility and industrial electrical systems. The assembly covers control and protection for potential transformers, capacitor feeders, and motor feeders, with a compact, lightweight build suited to panel rooms where footprint and handling matter.
Standards and Operational Ratings
IEC 62271-200:2011 compliance aligns the switchboard with recognized safety and performance benchmarks for medium voltage switchgear. Operational voltage is specified as 12 kV and 36 kV classes, with current ratings from 630A to 3150A, enabling alignment with varied feeder loads and network configurations.
Draw-Out Construction for Service Access
Draw-out type breakers and PTs support controlled withdrawal for inspection, testing, and replacement procedures. This configuration helps maintenance teams manage servicing without unnecessary disruption, while maintaining structured safety practices expected in medium voltage panel environments.
Monitoring and Interface Integration
SCADA-ready centralized monitoring supports integration into supervisory control systems for coordinated substation or plant-level oversight. A front-facing mimic display provides clear operational visibility, supporting routine switching operations and status verification within controlled electrical rooms.
Mechanical Build and Configuration Details
Aluminium or copper busbar options allow specification alignment based on conductivity and project standards. The enclosure carries an IP5X protection rating with 80–120 micron coating thickness and Siemens Grey RAL 7032 finish, with top or bottom cable entry and control voltages of 24VDC, 110VDC, or 220VDC.
