Verimliliği ve Güç Faktörünü En Üst Düzeye Çıkarın
A Low Voltage Power Capacitor typically refers to a power capacitor with a rated voltage between 400V and 6kV. It operates by injecting capacitive reactive power into the system to offset the inductive reactive power generated by inductive loads (e.g., motors, transformers), thereby actively correcting the grid’s power factor.
| Fonksiyonlar | Description |
|---|---|
| Güç Faktörü Düzeltme | Boosts power factor (PF) from 0.6-0.8 to ≥0.95, eliminating utility penalty charges and improving grid efficiency. |
| Gerilim Stabilizasyonu | Reduces voltage drop during heavy load startup and operation, maintaining stable power supply quality. |
| Harmonic Suppression (with detuned reactors) | Mitigates harmonic currents, protecting sensitive equipment from waveform distortion and reducing overheating risks. |
| Energy Efficiency Improvement | Cuts I²R losses in cables and transformers by 10-20%, lowering overall energy consumption and operational costs. |
| Reactive Power Compensation | Supplies local reactive power to inductive loads, reducing the reactive power drawn from the main grid and optimizing system capacity. |
| Equipment Life Extension | Minimizes voltage fluctuations and overheating caused by low PF and harmonics, extending the service life of motors, transformers, and distribution gear. |

Our low voltage power capacitor utilizes high-quality metalized polypropylene film as the dielectric, offering excellent self-healing performance. In case of a localized dielectric breakdown due to overvoltage, it rapidly restores insulation within microseconds, greatly enhancing product reliability and service life.
Low voltage power capacitor’s dissipation factor (tan δ) is extremely low, typically below 0.1%. This means the low voltage power capacitor’s own energy loss is minimal, resulting in lower operating temperatures and more pronounced energy-saving effects.
Employing new materials and optimized structures, our low voltage power capacitors have a volume and weight only 1/4 to 1/5 of traditional products, saving installation space in distribution cabinets and facilitating transportation and installation.
Utilizes dry technology, filled with inert gas or environmentally solid impregnants, eliminating the risk of oil leakage, ensuring safety and environmental friendliness. Built-in overpressure disconnector / explosion-proof device and discharge resistors ensure rapid discharge after power-off, safeguarding maintenance operations.
Our low voltage power capacitor's design complies with international and national standards such as IEC 60831 and GB 12747. Capable of stable operation within a wide ambient temperature range of -25°C to +50°C, with a design lifespan exceeding 100,000 hours.

ZHIMING Low Voltage Power Capacitors cover rated voltages including 400V, 450V, 480V, 525V, up to 690V, and other common low-voltage levels. Single-unit capacities typically range from 1 kvar to 80 kvar, allowing flexible configuration based on your specific compensation needs.
This depends on your load distribution. Centralized compensation is installed in the main distribution room, offering lower equipment costs and simpler installation, but has a limited effect on reducing line losses. Localized compensation (decentralized compensation) is installed directly beside large inductive loads, providing the best compensation effect and maximizing line loss reduction, but requires a higher initial investment. The ZHIMING technical team can assess the optimal solution for you.
“Self-healing” refers to the capacitor’s ability to restore normal operation when a localized breakdown occurs in the internal dielectric due to a transient overvoltage. The metalized electrode around the breakdown point evaporates instantaneously, isolating the fault point. This feature significantly enhances the capacitor’s overload withstand capability and operational reliability, preventing total failure due to minor defects, making it a crucial safety feature in modern capacitors.
Yes, ZHIMING’s primary products utilize advanced Dry Type technology (GMKP). Compared to traditional oil-impregnated power capacitors, dry-type power capacitors are filled with special gases or solid dielectrics, eliminating the issue of oil leakage and pollution. They offer advantages such as flame retardancy, explosion-proof characteristics, and maintenance-free operation, making them safer and more environmentally friendly.
