Why choose Jinneng Cylindrical Power Capacitor?

 

Key Quality Advantages of Jinneng 440V 525V Cylindrical Power Capacitor

 (100% from Test Reports)

 

1. Ultra-Long Life & High Stability

Completed 1,500-hour severe ageing test:1.25× Un × 750h + 1,000 charge-discharge cycles + 1.25× Un × 750h.No failure, no performance degradation, no breakdown, no bulge.

Excellent thermal stability with very low temperature rise, suitable for long-term full-load operation.

 

2. Ultra-Low Loss & High Efficiency

Dissipation factor (tanδ): 0.0003–0.0011, far below IEC limit ≤0.0015.

Capacitance tolerance controlled within –0.5% ~ +1.8%, much better than IEC standard.

 

3. Superior Insulation & Impact Strength (Indoor Type → Outdoor Level)

Terminal-to-container insulation: 6kV (indoor product meets outdoor standard)

Lightning impulse withstand voltage: 15kV

Between-terminal withstand voltage: 2.15× Un, no flashover, no breakdown.

 

4. High Safety & Protection

Excellent self-healing performance: capacitance change ≤0.08% after breakdown,almost no attenuation.

Dry-type, sealed structure: no liquid leakage, maintenance-free.

External discharge resistor: keeps the capacitor cool, extends service life, improves safety, allows easy maintenance, and is far more reliable for high-temperature & high-humidity environments.

 

5. Full Test Certification

All routine and type tests according to IEC 60831-1&2:2014 fully passed, certified by TÜV Rheinland & National Laboratory, suitable for global power grid, PV, industry, and high-end projects.

 

Summary:

• The capacitor insulation, lifespan, loss, and accuracy are all at the forefront of the industry.
• It has passed all the requirements of IEC 60831 and TÜV certification, and is one of the very few manufacturers in China that can complete the certification.
• It is suitable for photovoltaic, industrial, power grid, and high-end overseas markets.
• Jinneng's cylindrical power capacitor is among the top-tier in the high-end category in China, with export quality at the grid level. It achieves the highest domestic standards in key indicators such as insulation strength, aging life, low loss, capacity accuracy, and safety. Its overall performance is superior to that of most manufacturers, and it is at the same level as or even stronger than some of the leading domestic brands.
