◆ Product Advantages
- Cylindrical Aluminum Case with Classic and Reliable Structure: Aluminum alloy cylindrical housing design provides robust construction, excellent sealing, and high protection rating, demonstrating outstanding environmental adaptability in industrial sites with significant temperature and humidity variations — a classic product form with an excellent reliability track record, long validated by the low-voltage reactive power compensation market
- Over-Pressure Safety Protection Device for Proactive Circuit Disconnection: Built-in automatic over-voltage circuit-breaking protection mechanism actively disconnects the circuit when the capacitor is subjected to excessive voltage, fundamentally eliminating explosion and fire risks from over-voltage conditions and fully protecting distribution equipment and on-site personnel
- Metallized Film Self-Healing Property for Significantly Extended Service Life: Advanced metallized polypropylene film rapidly self-heals to restore insulation after localized breakdown, effectively suppressing further propagation of localized defects, significantly improving product reliability with a design life exceeding 10 years under rated operating conditions
- Wave-Cutting Technology for Enhanced In-Rush Current Resistance: Proprietary wave-cutting process effectively improves the capacitor's ability to withstand grid in-rush currents during switching, reducing early damage caused by frequent switching and large in-rush currents, ensuring long-term stable operation of capacitors in automatic compensation devices
- Low Loss and Long Service Life to Reduce Total Lifecycle Cost: Premium film materials and precision manufacturing processes ensure low tanδ values with minimal heat generation and slow performance degradation during extended operation, effectively reducing maintenance costs associated with frequent capacitor replacement

◆ Key Selling Points
- High Market Maturity with Strong Compatibility with Mainstream Compensation Panel Dimensions: Product dimensions comply with industry-standard compensation panel installation specifications, enabling direct replacement of same-type capacitors in existing systems without cabinet structural modifications, reducing upgrade and replacement costs
- Flexible Configuration Supporting Multiple Compensation Solutions: Suitable for standalone individual compensation as well as multi-unit parallel or grouped switching configurations, flexibly adapting to various low-voltage reactive power compensation solutions including shared and split compensation schemes
- Integration with Reactors for Harmonic Filter Circuits: Supports series reactor connection to form anti-harmonic LC filter compensation groups, combining compensation and filtering functions in industrial grid environments with high harmonic content
- Comprehensive Multi-Specification Coverage for Convenient Selection: Available in multiple specifications from low to high capacitance with voltage coverage from 230V to 690V, meeting compensation capacity requirements of various projects with convenient and straightforward product selection

◆ Primary Applications
- Power factor compensation in industrial, mining, and commercial building low-voltage distribution systems
- Grouped automatic switching of capacitors in automatic reactive power compensation devices (APC)
- AC harmonic filter compensation circuits in combination with series reactors
- Bus reactive power compensation on substation low-voltage sides
- Reactive power compensation improvement at the end of rural and remote area grids
