Flagship Product Lines & Innovations

1. NXSAFE Metal-Clad Switchgear (12-40.5kV):

• Features: Air-insulated, removable design, arc-resistant construction (IAC certified), independent pressure-relief channels, and full "Five-Prevention" interlocking for operator safety.

• Applications: Substations, data centers, large industrial plants.

• USP: Standardized design ensures operational continuity and easy installation (front cable access, wall-mountable).

2. R-AIR & NXGREEN Eco-Friendly Switchgear:

• Innovation: Pioneering SF6-free solutions using clean, dry air insulation (R-AIR) and sealed air-insulated designs (NXGREEN). Eliminates greenhouse gas risks.

• Benefits: Environmentally sustainable, fully enclosed, compact footprint. Ideal for green buildings and eco-sensitive zones.

3. NXRING & SOGEAR Ring Main Units (RMUs):

• Options: Gas-insulated (SF6 - NXRING) or Solid Insulated (SF6-Free - SOGEAR).

• Flexibility: Modular units (CB, load switch, fuse combos, metering) for ring networks, renewables integration, and compact substations.

• NXRING-ATS: Automatic dual-power transfer system for critical loads.

4. VHZ4 Series Vacuum Circuit Breakers (12-40.5kV):

• Range: Side-mounted (VHZ4), withdrawable (VHZ4-24/40.5), and intelligent (VHZ4i) versions.

• Technology: Solid-epoxy poles, spring/perm-mag mechanisms, online monitoring (VHZ4i). Rated up to 4000A/40kA.

• Applications: Primary/secondary distribution, motor/frequent switching.

5. EXSINE & EXE Low-Voltage Solutions:

• EXSINE LV Draw-Out Switchgear: High-current (6300A), strong SQUARE steel frame, IP protection, DAVIDCLOUD integration for smart monitoring.

• EXT/EXE Circuit Breakers: Smart EXE-HIC series (0.5-5.0) with communication, EXS minis, EXVAR capacitors, EXAPF active filters for power quality.

6. DAVIDCLOUD Smart O&M Platform:
