The Foundation of Stability: How High-Voltage Ceramic Capacitors Become the Stabilizing Force of Industrial Electrostatic Equipment
At the core of industrial electrostatic equipment (such as electrostatic precipitators and electrostatic spraying systems), the stability of the high-voltage power supply directly determines the efficiency and reliability of the entire system. The key to ensuring this stability often lies in a seemingly simple yet technologically advanced component: the high-voltage ceramic capacitor. It not only manages energy but also safeguards the safe operation of the system.
Unique Challenges of Industrial Electrostatic Applications
Unlike brief pulses, industrial electrostatic equipment requires high-voltage power supplies to continuously and smoothly output DC voltages ranging from tens to hundreds of kilovolts. This requirement presents three core challenges:
Sustained High-Voltage Stress: Capacitors must withstand DC voltages close to their rated value 24/7. Any minor defect can cause dielectric breakdown.
Ripple Current and Thermal Management: The ripple current generated by the power inverter circuit causes capacitors to heat up. Long-term heat accumulation accelerates aging and may even cause thermal runaway.
Harsh industrial environments: Dust, humidity, temperature fluctuations, and potential chemical corrosion place severe challenges on component packaging and reliability.
Our Solution: Designed for Industrial Durability
To address these challenges, our high-voltage ceramic capacitors, designed specifically for industrial high-voltage power supplies, offer comprehensive solutions:
Superior Dielectric Strength and DC Bias Characteristics
Using a specially stabilized ceramic dielectric material, our DC breakdown field strength far exceeds industry standards. We guarantee extremely low leakage current and excellent long-term stability at rated voltage for each capacitor, effectively withstanding sustained DC stress and eliminating premature failure at the root cause.
Optimized Low Dissipation Factor and Thermal Management
Through our unique electrode design and material formulation, we achieve an extremely low loss tangent for the capacitors. This means less heat is generated while handling the same ripple current. The optimized metal housing and thermally conductive epoxy encapsulation achieve efficient heat dissipation, ensuring long life and low temperature rise under full load.
Rugged Industrial-Grade Package
The fully sealed (epoxy potted) structure effectively resists moisture, dust, and most industrial chemical environments. Terminals are reinforced with welds or bolts, ensuring reliable connections even in vibrating environments.
