Metal-Clad Switchgear

Features of TRONKI Metal Armored Switchgear

✅ Enhanced Safety & Arc Containment

Each circuit is enclosed within independent metal barriers, ensuring any arc flash or short circuit is confined to a single compartment. This prevents fault propagation and protects both adjacent components and personnel. The cabinet structure is arc-resistant and tested in accordance with IEEE standards.

✅ Modular and Flexible Design

Plug-in circuit breaker modules and standardized compartments enable expansion or reconfiguration without shutdown. Modules are hot-swappable and interlocked for safety, simplifying maintenance and supporting future system upgrades.

✅ High Reliability and Durability

Built with a robust galvanized steel frame, premium insulation materials, and precision engineering, TRONKI switchgear offers long-lasting performance. High-quality vacuum circuit breakers ensure low maintenance and high operational reliability. Custom brand specifications are available.

✅ Easy Maintenance & Smart Monitoring

Withdrawable breaker units and automatic shutters allow for safe maintenance without powering down the entire cabinet. Technicians can easily isolate compartments for servicing. Optional digital diagnostics and remote monitoring reduce on-site inspections.

Compared to conventional distribution panels, TRONKI metal-clad switchgear offers superior safety, uptime, and maintainability—minimizing downtime and total lifecycle costs.

Technical Specifications & Comparison

• Rated Voltage: 4.8kV to 38kV
• Busbar Current Rating: 1,200A to 4,000A
• Short-Circuit Rating (Icu/Ics): 25kA to 50kA (1–3 seconds)
• Insulation Type: Air Insulated (AIS); optional hybrid with GIS components
• Primary Components: Vacuum or SF₆ circuit breakers, load break switches, instrument transformers
• Standards Compliance: IEEE C37.20.2 / IEC 62271-200 / GB3906

Unlike metal-enclosed switchgear (e.g. IEEE C37.20.3), which shares a common compartment, metal-clad switchgear provides fully isolated chambers, offering superior fault isolation and interrupting capacity—ideal for utilities and heavy-duty industrial applications.
