Why Choose This Tapered-Profile Capacitor?

The LQHVF 200kV/300pF represents a breakthrough in high-voltage capacitor design. Its unique tapered profile (Ø320mm base to Ø650mm corona) creates a natural gradient that optimizes electric field distribution, reducing measurement errors caused by edge effects. The oversized corona rings suppress partial discharge below 5pC at full 200kV operation, while the wide base provides exceptional stability in harsh environments. The oil-immersed ONAN cooling system ensures thermal stability during extended 60-minute tests, and the modular construction allows for efficient field maintenance. Certified to international standards including IEC 60270 and IEEE 4, this solution is ideal for utilities, renewable energy projects, and industrial facilities where measurement precision and reliability are critical.
