Product Advantages

1. Ultra-Low Loss & High Stability

Loss Tangent: ≤0.0002; Power Loss: <0.2 W/kvar; Temperature Rise: ≤15 K at full load.
The ultra-low loss and exceptional stability of this capacitor ensure minimal energy dissipation, leading to high efficiency in power systems. This feature not only reduces operational costs but also enhances the reliability of the power grid by maintaining optimal performance under varying loads.
With a temperature rise of just 15 K at full load, this capacitor ensures that it operates within safe thermal limits, preventing overheating that could otherwise shorten its lifespan or cause failures.
Lifespan: ≥20 years; Capacitance Tolerance: ≤±3% (phase-to-phase).
Engineered for durability, the capacitor offers a lifespan of at least 20 years, making it a cost-effective long-term solution for reactive power compensation. Its phase-to-phase capacitance tolerance is maintained within a strict limit of ±3%, ensuring consistent performance over its extended operational life.

2. All-Film Dielectric Technology

Self-Healing Metallized Film Structure: Capable of withstanding 13.2 kV (max operating voltage).
The capacitor uses an all-film dielectric technology, a self-healing metallized film structure, which significantly enhances its reliability. When a failure occurs in the dielectric, the self-healing property allows it to automatically restore the integrity of the capacitor, ensuring continued operation without the need for immediate replacement.
Rupture Energy: 15 kJ, surpassing the safety of oil-immersed capacitors.
With 15 kJ rupture energy, this capacitor offers superior safety compared to traditional oil-immersed capacitors. In case of an overload or failure, it safely discharges the stored energy, reducing the risk of catastrophic failures, thus providing a higher level of operational security.

3. Eco-Friendly & Extreme Environment Resilience

Chlorine-Free C101 Oil: Ensures an environmentally friendly insulating medium.
The capacitor is filled with chlorine-free C101 oil, which eliminates harmful substances typically found in traditional capacitors, making it a greener option for the environment. This choice supports eco-conscious power solutions without compromising performance.
IP54 Protection: Suitable for environments with high humidity (≤95% RH) and salt fog.
The IP54 rating ensures that the capacitor is highly resistant to dust, moisture, and water splashes, providing reliable protection even in harsh environments such as coastal areas with high salt fog or high-humidity regions. This feature enhances the product's longevity and makes it highly suitable for various outdoor and industrial applications.

4. Customizable Configurations

Capacity Gradation: Available in sizes from 50–750 kvar to meet specific system needs.
This capacitor offers customizable capacity options ranging from 50 kvar to 750 kvar, allowing it to be tailored to specific grid requirements or industrial applications. Whether it’s for small-scale or large power systems, you can select the optimal size for your needs.
Design Options: Available in single-phase and three-phase designs, with toroidal core options.
The flexibility in design allows the capacitor to be used in different types of electrical systems. You can choose between single-phase and three-phase configurations, as well as a toroidal core design for specific use cases. This versatility makes it compatible with a variety of transformer systems, including rectifier transformers and power transformer systems, ensuring seamless integration with existing infrastructure.
