1. Define Core Requirements
- Voltage Rating: Confirm system voltage (e.g., 400V/690V) and fluctuation range
- Capacity Requirement: Calculate required reactive compensation (kvar) based on load characteristics
- Environmental Conditions: Special operating conditions like temperature (-25℃~+50℃), humidity, altitude
2. Key Performance Indicators
✅ Loss Value: Opt for low-loss models with dielectric loss <0.2W/kvar
✅ Service Life: Select durable products with ≥100,000 hours design life
✅ Safety Certifications: Must comply with IEC 60831/GB/T 12747 standards
✅ Protection Rating: IP20+ (dust-proof) or IP54 (outdoor models)
3. ZHIMING Product Advantages
• Smart Capacitors: Built-in temperature protection and over-voltage trip devices
• Modular Design: Supports quick capacity expansion and maintenance
• Eco-Friendly Materials: Dry-type oil-free structure compliant with RoHS directive
4. Supplier Evaluation Criteria
◇ Project References: Require successful case studies in same industry
◇ Warranty Terms: Prefer suppliers offering ≥5-year quality guarantee
◇ Technical Support: Prioritize vendors providing system simulation and installation guidance
ZHIMING Recommendation:
For continuous production facilities, we recommend integrated solutions with «automatic switching devices + smart capacitor banks» achieving 15%-30% comprehensive energy savings.
