What is the maximum voltage rating for HVC high voltage resistors?
HVC Capacitor's high voltage thick film resistor portfolio spans from 5kV through 150kV DC rated voltage, with custom-engineered solutions available up to 200kV+ for specialized applications requiring extreme voltage handling capability.
| HVR Series | Form Factor | Min Voltage | Max Voltage | Standard Range | Power Rating |
|------------|------------|-------------|-------------|---------------|-------------|
| HVR-GFP | Flat Planar (Small) | 5kV | 20kV | 5, 10, 15, 20 kV | 3W – 10W |
|---|---|---|---|---|---|
| HVR-GXP | Flat Planar (Large) | 10kV | 50kV | 10, 15, 20, 30, 40, 50 kV | 10W – 50W |
| HVR-GHP | High-Power Planar | 15kV | 35kV | 15, 20, 25, 30, 35 kV | 25W – 100W |
| HVR-BSP | Tube Style (Standard) | 10kV | 70kV | 10, 20, 30, 40, 50, 60, 70 kV | 10W – 75W |
| HVR-BOP | Tube Style (High-Power) | 20kV | 100kV | 20, 30, 40, 50, 60, 70, 85, 100 kV | 25W – 200W |
| HVR-Custom | Per-specification | 5kV | 150kV+ | Any voltage on request | Per spec |
For applications exceeding 100kV — such as:
* Particle accelerator beam-line instrumentation
* High-energy physics experimental apparatus
* Ultra-high-voltage test equipment calibration
* Power transmission substation monitoring (220kV – 500kV grids)
HVC develops custom multi-stage resistor networks using series-stacked HVR-BOP elements with intermediate shielding and grading ring structures to ensure uniform electric field distribution. These custom solutions have been deployed in Chinese Academy of Sciences research facilities and State Grid ultra-high-voltage laboratory installations.
