15kV Medium-Voltage Switchgear
High fault tolerance, metal-clad isolation, and 10-14 week delivery. ERONZON EP 15kV metal-clad switchgear follows IEEE C37.20.2, ANSI, and IEC standards for core medium-voltage control and protection.
- Core CapabilityERONZON EP 15kV metal-clad switchgear is designed to IEEE C37.20.2, ANSI, and IEC standards, providing core control and protection for medium-voltage networks.
- Target ApplicationsBuilt for high-load core power nodes, including transformer primary and secondary switching, Main-Tie-Main automatic transfer schemes, full-voltage medium-voltage motor starting, and main distribution networks for heavy industry and data centers.
- Metal-Clad IsolationFour isolated compartments use grounded metal barriers. When the VCB truck is withdrawn, steel shutters automatically cover live stationary contacts to reduce physical risk during maintenance.
- Interlock ProtectionIntegrated mechanical and electrical interlocks help prevent hazardous operations such as racking breakers under load or closing grounding switches while energized.
Product Advantages
A modular prefabricated frame structure reduces manufacturing bottlenecks and gives medium-voltage main distribution nodes a more controllable project timeline.
Core components can align with globally available vacuum circuit breakers and protection relays, improving spare-parts availability and reducing aftermarket dependency.
Front operation and maintenance support wall-adjacent installation, improving usable area in space-constrained electrical rooms.
Metal-clad construction, vacuum breakers, and strict interlocks improve safety for critical infrastructure.
