Electrical Specifications

Graded Partial Discharge Performance

Tested per IEC 60270 with shielded measurement environment.

Honeycomb Thermal Management System

• Core Structure: Nickel-chromium wire wound on epoxy boards

• Heat Dissipation: Open honeycomb configuration maximizes surface area

• Thermal Performance: <100K temperature rise after 60-min continuous operation

• Material Stability: Maintains mechanical strength at operational temperatures

The hexagonal cell structure enables natural convection cooling with 40% greater efficiency than solid-core designs.

Discharge Protection System

Triple Shielding Rings:

• Dual end-ring electrodes with 300mm radius

• Central grading ring at midpoint

• Electro-polished aluminum construction

Prevents insulation damage during test object discharges by controlling electric field distribution.

Operational Endurance

• Continuous Operation: 60 minutes at 1200kV/0.5A

• Thermal Recovery: 90-minute cooldown between full-power tests

• Resistance Stability: ±0.1% deviation during thermal transients

Structural Advantages

High-Stress Applications
