Main Features and Advantages
Self-Healing Technology: Our capacitors use advanced metallized polypropylene film with self-healing capabilities. When voltage surges occur, the metallization around breakdown points evaporates instantly, restoring insulation automatically.
Space-Efficient Design: The rectangular form factor allows modular stacking in switchgear cabinets. You can achieve higher energy density compared to cylindrical alternatives.
Enhanced Safety: Built-in overpressure disconnectors physically separate terminal leads if internal pressure rises. This prevents case rupture and ensures operator safety.
Superior Thermal Management: The modular square arrangement improves airflow channels and heat dissipation in high-density capacitor banks.
Flame-Retardant Construction: Non-flammable dry resin filling eliminates leakage risks and fire hazards associated with oil-filled units.
Low Loss Operation: Extremely low dissipation factor (≤0.2W/kVAR) ensures minimal internal heating and maximum efficiency.
Practical Applications
Heavy Industrial Plants: Steel mills, automotive manufacturing, and chemical processing facilities benefit from our compact capacitor banks. The Square Capacitor for Reactive Power Compensation compensates for large motor and transformer loads while minimizing electrical room footprint.
Renewable Energy Systems: Wind and solar installations require robust power quality solutions. Our square capacitors provide mechanical stability against vibrations in turbine nacelles and containerized substations.
Motor Control Centers: Direct mounting capabilities make these units ideal for local compensation at heavy-duty motors, pumps, and crushers. They withstand harsh start-up currents and thermal cycling.
Commercial Buildings: Shopping centers, hospitals, and office complexes use our capacitors in automatic power factor correction panels to reduce demand charges and improve power quality.
How It Works
Power factor correction addresses the phase difference between voltage and current in inductive loads. When motors and transformers operate, they create reactive power that doesn't perform useful work but increases total current demand.
Our capacitors supply leading reactive power to counteract lagging reactive power from inductive loads. This brings the power factor closer to unity (1.0), reducing:
- kVA demand charges
- Line losses
- Voltage drops
- Equipment heating
The metallized polypropylene film stores electrical energy in the electric field between its plates. The square housing design allows multiple units to work together efficiently in banks, providing precise reactive power compensation.

FAQ
Q: What maintenance is required for square capacitors?
A: Check terminal torque specifications every 12 months to prevent hot spots. Ensure cooling fans operate properly and inspect for casing bulging that indicates potential failure.
Q: Can these capacitors handle harmonic distortion?
A: Standard units work with linear loads. For environments with THD exceeding 15-20%, use detuning reactors and select higher voltage ratings.
Q: How long do these capacitors last?
A: Rated for over 100,000 operating hours under standard conditions. End-of-life occurs when capacitance drops below 90-95% of initial value.
Q: Are square capacitors safer than oil-filled units?
A: Yes. Our dry-type construction with flame-retardant materials (UL94-V0) eliminates leakage and fire risks associated with liquid dielectrics.
Q: What determines the required capacitor rating?
A: Calculate based on your system's reactive power requirements, typically determined by power factor measurements and load analysis.
