Main Features and Advantages
Our capacitor banks feature self-healing MKP dielectric systems for maximum reliability. You get dry-type resin impregnation that eliminates oil leakage risks completely. The aluminum cylindrical casing provides superior heat dissipation for extended operation.
Built-in overpressure disconnectors act as safety fuses. They prevent case rupture during fault conditions. Integrated discharge resistors ensure safe maintenance by reducing voltage quickly.
Low dielectric losses mean efficient operation and minimal heat generation. The robust construction withstands harsh industrial environments. You'll experience consistent performance across temperature variations.
Practical Applications
Automatic Power Factor Correction Panels: Your manufacturing plant benefits from centralized banks with multiple units. Controllers dynamically match load fluctuations. This prevents leading power factor during off-peak hours.
Direct Motor Compensation: Connect directly with 30-50 kW induction motors. Mining and cement industries use this configuration. You reduce cable sizing requirements and switchgear costs upstream.
Harmonic-Rich Environments: Pair with detuned reactors in high-distortion networks. This 25 kvar capacitor bank configuration prevents resonance. You maintain effective compensation while protecting against harmonic amplification.
How It Works
The capacitor stores electrical energy in its dielectric field. When connected to your power system, it releases leading reactive power. This counteracts the lagging reactive power from inductive loads.
Your power factor improves toward unity (1.0). The apparent power demand decreases significantly. Current flow reduces throughout your electrical system. Energy efficiency increases while utility penalties disappear.
The self-healing technology automatically isolates minor dielectric breakdowns. Operation continues without interruption. This ensures long-term reliability in demanding applications.

FAQ
Q: What's the expected lifespan?
A: Quality units offer 100,000 to 130,000 hours of design life. Proper operating conditions within rated temperature and voltage limits are essential.
Q: Can I use standard units in high-harmonic networks?
A: No. You need higher voltage-rated capacitors with harmonic reactors. Standard units will overheat and fail from harmonic currents.
Q: How often should I check discharge resistors?
A: Check resistors during annual maintenance cycles. Faulty resistors create safety hazards as capacitors remain charged.
Q: What causes capacitor swelling?
A: Bulging indicates overpressure disconnector activation or internal pressure buildup. Replace these units immediately.
Q: What contactors should I use?
A: Use capacitor-duty contactors with pre-insertion resistors. They limit massive inrush currents up to 200x rated current.
