◆ Product Advantages
- Square Structure for High-Density Compensation Panel Installation: Standard square housing design enables neat and compact arrangement inside compensation panels, achieving high compensation density per unit space, maximizing cabinet utilization, effectively reducing distribution room footprint — practical and economical for both new and retrofit low-voltage power distribution systems
- Dual Protection: Safety Device and Self-Healing Function: Built-in mechanical over-pressure protection device automatically disconnects when the capacitor is subjected to excessive voltage, eliminating explosion and fire hazards at the source; metallized film simultaneously provides self-healing capability, automatically restoring insulation after localized breakdown — dual mechanisms ensuring long-term safe and stable operation
- Wave-Cutting Technology for Outstanding In-Rush Current Resistance: Proprietary wave-cutting film processing technology significantly enhances the capacitor's ability to withstand grid in-rush current surges at the moment of switching, reducing early failures caused by in-rush currents and extending the overall service life of capacitors and associated controllers
- Low Loss with Significant Energy-Saving Effect: Extremely low dielectric dissipation factor (tanδ) results in minimal heat generation and self-energy consumption during extended operation, delivering outstanding energy-saving and cost-reduction benefits, ideal for industrial and commercial power distribution users sensitive to operating costs
- Multi-Function Power Quality Improvement: In addition to reactive power compensation, simultaneously provides energy storage, three-phase voltage balancing, line loss reduction, and improvement of power system stability and efficiency, comprehensively enhancing low-voltage grid power quality

◆ Key Selling Points
- Significant Power Factor Improvement with Substantial Electricity Cost Savings: Effectively compensates reactive power in low-voltage power supply systems, improving power factor from below 0.7 to above 0.95, significantly reducing reactive current and decreasing transformer and line losses for considerable annual electricity cost savings
- Wide Compatibility with Automatic Compensation Control Panels: Compatible with mainstream domestic and international low-voltage reactive power compensation controllers (APC controllers), supporting grouped automatic switching control with fast response speed and high compensation accuracy
- Flexible Integration with Reactors for Filter Circuits: Supports series reactor configuration to form LC harmonic filter compensation units, suitable for complex grid environments containing harmonic sources such as frequency converters and rectification equipment, combining reactive power compensation with harmonic management
- Comprehensive Coverage of Multiple Voltage Ratings and Capacitance Specifications: Available in multiple rated voltages including 230V, 400V, 440V, and 525V, with capacitance ranging from several kvar to tens of kvar, meeting power distribution systems of different scales and requirements

◆ Primary Applications
- Reactive power compensation in factory workshop and industrial park low-voltage distribution systems
- Energy-saving retrofit for office buildings, commercial complexes, and data center power distribution
