Maximice la eficiencia y el factor de potencia
A High Voltage Power Capacitor typically refers to a capacitor used in AC power systems with voltage levels from 6kV to 110kV and above. It provides capacitive reactive power to the system to balance the reactive consumption generated by inductive loads like transformers and motors, thereby achieving power factor correction, maintaining system voltage stability, and improving power quality.
| Funciones | Descripción |
|---|---|
| Corrección del factor de potencia | Boosts system PF from 0.6–0.8 to ≥0.95, eliminating utility reactive power penalties and optimizing grid capacity. |
| Voltage Regulation & Stabilization | Minimizes voltage drop during large load fluctuations and long transmission lines, maintaining stable system voltage. |
| Supresión de armónicos (con reactores desintonizados) | Filters harmonic currents, preventing resonance and protecting high-voltage equipment from waveform distortion. |
| System Capacity Optimization | Reduces reactive power flow, freeing up transformer and distribution line capacity for additional loads. |
| Energy Loss Reduction | Cuts I²R losses in overhead lines, cables, and transformers by 10–20%, lowering operational energy waste. |
| Mejora de la estabilidad de la red | Improves voltage profile and reduces line losses, supporting stable operation of medium/high-voltage distribution networks. |

High voltage power capacitor utilizes high-quality all-polypropylene film (all-film) as the dielectric, impregnated with environmentally friendly insulating fluid (non-toxic, non-PCB), achieving very low dielectric losses (typically below 0.2 W/kvar) for significant energy savings.
The high voltage power capacitor is made of high-quality steel with sealed welding, offering high mechanical strength and weather resistance. Integrated discharge resistors ensure residual voltage reduces to a safe level within a specified time (e.g., 10 minutes) after de-energization, ensuring personnel safety.
Product design complies with relevant international standards, capable of stable operation within a wide ambient temperature range of -40°C to +45°C (or wider). High voltage power capacitor‘s assembled or Tank-type designs are compact and easy to maintain, especially suitable for outdoor substations and other sites with limited space and complex environments.

ZHIMING High Voltage Power Capacitors cover standard rated voltages from 6kV, 10kV, 35kV up to 110kV. The capacity of a single capacitor unit can be customized based on project needs, covering a wide range. For example, the capacity of an assembled capacitor bank can reach thousands of kvar.
Safety is the primary principle. During a total station power outage, the power capacitor bank circuit breaker should be opened first. When re-energizing, the power capacitor bank should be the last to be switched on. Energizing a charged power capacitor is strictly prohibited. Before re-closing, ensure the power capacitor is fully discharged (typically requiring waiting at least 3-5 minutes after disconnection).
To ensure safe operation, HV power capacitors are typically equipped with unbalanced current protection, overvoltage protection, overcurrent protection, and instantaneous protection. Additionally, internal power capacitor elements may be fused to quickly isolate a failed component, allowing the rest of the bank to continue operating.
Yes. ZHIMING places high importance on product compliance and global applicability. Our High Voltage Power Capacitors, including assembled types, are designed and tested in accordance with major international standards such as IEC and IEEE, ensuring they meet the technical performance, safety, and reliability requirements for power grids and industrial applications worldwide.
