◆ Product Advantages
- Class B Mechanical Anti-Explosion (S2 Safety Level) — Preferred for Public Lighting: Lighting power factor compensation Class B mechanical anti-explosion aluminum case capacitors use a Class B built-in mechanical anti-explosion structure (S2 safety level) where the pressure relief valve actively actuates upon internal abnormalities, effectively preventing housing rupture — the preferred product for high-safety-requirement lighting applications in public spaces, underground parking lots, and hospitals
- Built-In Discharge Resistor for Fast Discharge After Power-Off to Ensure Maintenance Safety: Product integrates a bleed resistor internally, quickly discharging stored charges to a safe potential level after power-off, allowing maintenance personnel to operate safely and complying with electrical safety specification requirements
- Fully Sealed Aluminum Case with Weather and Corrosion Resistance: Aluminum case fully sealed structure provides moisture-proof, dust-proof, and corrosion-resistant properties, suitable for installation in various harsh lighting environments such as damp basements and semi-outdoor parking lots
- Compatible with High and Low Pressure Sodium and Mercury Lamps: Product electrical parameters specifically optimized for power factor compensation requirements of high-pressure sodium lamps (HPS) and mercury lamps (HPM) with excellent compensation effect and good matching with paired ballasts
- Self-Healing and Low Loss: Metallized film self-healing characteristic combined with low dielectric loss design ensures long-term reliable operation with low self-energy consumption

◆ Key Selling Points
- Significant Power Factor Compensation Effect Saving Electricity Costs: After installing this product in high-pressure sodium lamp and mercury lamp lighting circuits, power factor is greatly improved from 0.3~0.5 to above 0.9, significantly reducing lighting system electricity costs
- Built-In Bleed Resistor Eliminating External Discharge Components: Integrated design simplifies internal circuits of lighting fixtures, reducing material costs and installation labor
- Wide Compatibility with Various Brand High-Pressure Sodium Lamp Ballasts: Compatible with mainstream ballast brands on the market for convenient replacement and maintenance
- Multiple Capacitance Specifications for Different Power Lamp Requirements: Covering 70W to 1000W high-pressure gas discharge lamps across various power segments

◆ Primary Applications
- Power factor compensation for high-pressure sodium lamp (HPS) street lights
- Compensation for high-pressure mercury lamp (HPM) industrial plant lighting
- Underground parking lot lighting systems
- High-pressure gas discharge lamp systems for tunnel lighting
- Lighting compensation for gymnasiums, warehouses, and airports
