Drawer Type LV Electrical Switchgear Electrical Switch Cabinet For Power Distribution

The Low-Voltage Drawer-Type Switchgear Cabinet is the premium solution for industries where power continuity and operator safety are the highest priorities. Unlike fixed-type panels, this Withdrawable (Draw-out) system allows each functional unit—whether it's a feeder or a motor starter—to be housed in an independent, removable drawer.

This modular architecture ensures that any single circuit can be isolated, tested, or replaced without de-energizing the main busbar or interrupting the power supply to other critical loads. Engineered for use in power plants, oil refineries, and data centers, our drawer-type switchgear provides a compact footprint with high-density circuit integration, meeting the most rigorous international standards for low-voltage power distribution.

• High-Density Modular Design: Each vertical section can accommodate multiple drawer units (ranging from 1/4 unit to 3-unit sizes), allowing for maximum circuit concentration in a minimal floor area.

• Rapid Maintenance (MTTR Reduction): Drawers are equipped with high-precision primary and secondary plug-in contacts. In the event of a fault, a drawer can be swapped for a spare in under five minutes.

• Four-Position Safety Interlocking: Every drawer features a mechanical indicator for Connected, Test, Disconnected, and Withdrawn positions. The system prevents the drawer from being moved while the circuit breaker is closed.

• Superior Arc-Flash Containment: The cabinet is divided into three distinct compartments: the Busbar Room, the Functional Unit Room (Drawers), and the Cable Room. This partitioning effectively prevents the spread of internal electrical arcs.

• Corrosion-Resistant Al-Zn Frame: Utilizing 2.0mm Aluminum-Zinc coated steel, the frame offers exceptional mechanical rigidity and high resistance to oxidation without requiring additional surface paint.

1. Industrial Process Control: Reliable Motor Control Centers (MCC) for chemical plants, steel mills, and cement factories.

2. Power Generation & Utilities: Main distribution boards for hydroelectric, thermal, and wind power substations.

3. Critical Infrastructure: Essential power hubs for airports, subway systems, and wastewater treatment plants.

4. Commercial Real Estate: High-capacity power distribution for skyscrapers, shopping malls, and Tier III/IV data centers.

• Silver-Plated Contact System: All primary plug-in contacts utilize high-purity silver plating to ensure low contact resistance and prevent overheating during continuous full-load operation.

• Smart Monitoring Integration: We offer "Intelligent Switchgear" configurations equipped with Modbus/Ethernet communication for real-time monitoring of energy consumption and thermal status.

• Bespoke Engineering: We build every panel board to your specific Single Line Diagram (SLD). We integrate world-class circuit breakers from brands such as Schneider, ABB, Siemens, or Chint.

• Seismically Reinforced Frames: Our cabinets are engineered to withstand high-vibration environments and are suitable for installation in high-seismic-risk zones.

Q: Can I replace a drawer unit while the main busbar is live?

A: Yes. The "withdrawable" design is specifically engineered for "hot-swapping." By moving the drawer to the "Disconnected" position, you can safely remove the unit for maintenance while the rest of the switchgear remains operational.

Q: What is the maximum number of drawers per cabinet?

A: Depending on the drawer height (e.g., 8E/4 or 8E/2 sizes), a single 2200mm vertical cabinet can house up to 36 small feeder units or 9-18 standard motor starter units.

Q: Do you provide the internal copper busbars?

A: Yes. We use high-conductivity T2 Copper for all horizontal and vertical busbars. We also offer specialized heat-shrinkable insulation tubing for enhanced safety.
