• NXGIS-40.5: Gas-insulated switchgear for secure, space-efficient 40.5kV applications.

• NXGREEN & NXPANEL: Eco-friendly air-insulated, sealed designs for box-type fixed and compact switchgear, prioritizing environmental responsibility.

2. Advanced Circuit Breakers:

• VHZ4 Series: Intelligent vacuum circuit breakers (12kV, 24kV, 40.5kV) with modular mechanisms, solid-insulated poles, real-time condition monitoring (VHZ4i), and ratings up to 4000A/40kA. Available in fixed (F) or withdrawable (E) configurations.

• VHZ4M: Ultra-fast vacuum breakers with permanent magnet actuators for capacitor/inductor switching and phase control.

• VHZ4 Side-Mounted: Fixed-mount breakers featuring solid-pole insulation for panel applications.

• NXATS: Dedicated medium-voltage dual-power transfer switches with patented interlocking.

• EXT Series: Intelligent air circuit breakers (6300A frame) with HiLogic controllers for LV protection, monitoring, and communication.

3. LV Distribution & Protection:

• EXSINE Low-Voltage Switchboards: Modular draw-out design (IP30-IP54) with strong SQUARE frame, up to 6300A busbar rating, 100kA SCCR, arc-flash protection, and integrated DAVIDCLOUD monitoring.

• EXE Series MCCBs: Thermomagnetic (HIC1.0), Earth Leakage (HIC2.0), and Advanced Electronic (HIC3.0/HIC5.0) molded case breakers with metering and communication (RS485, Modbus/DL/T645).

• EXS MCBs: Standard and residual current devices for end-circuit protection.

4. Power Quality & Compensation:

• EXVAR: Intelligent power capacitors with thyristor switching (EXTSC) for dynamic reactive compensation.

• EXAPF: Active Harmonic Filters for clean power (25-300A, 400-690V).

• EXCA Capacitors & EXRE Reactors: Low-voltage self-healing capacitors and series reactors for robust compensation systems.

5. Smart Grid & Integration:

• DAVIDCLOUD: Cloud-based intelligent operation and maintenance system for real-time monitoring, diagnostics, and predictive maintenance of power assets.

• MIC300/500: Protection, measurement, and control devices for feeder/motor protection.

• HIMETER194: Multifunctional power meters for advanced energy monitoring.

• NXLINE/EXLINK: Medium & Low Voltage quick coupling connectors for rapid emergency generator/load connection.

• EXATC: PC & CB级 Automatic Transfer Switches (ATS) for critical LV power source redundancy.

• PRESUB: Prefabricated substations (YB/U) and integrated European-style inverter/transformer units for renewables.
