Technical Specifications

Advanced Structural Design

Honeycomb Cooling System

Nickel-chromium resistance wire wound on epoxy boards in honeycomb configuration enables:

• Optimal air-thermal exchange

• Prevention of resistance degradation under heat

• Uniform temperature distribution

Triple-Shielding Protection

Shielding rings at both ends and center provide:

• Discharge path isolation during test object failures

• Prevention of insulation damage

• Reduced electromagnetic interference (EMI)

Performance Features

• Thermal Stability: Maintains material strength with <100K temperature rise at full load

• Current Handling: Sustains 0.5A continuous current for 60 minutes

• Voltage Endurance: Withstands 750kV without flashover

• Material Integrity: Nickel-chromium alloy maintains resistance stability at high temperatures

Critical Applications

• Impulse voltage generator protection

• HV transformer testing circuits

• Circuit breaker synthetic test setups

• High-power laboratory test systems

• Transmission line surge protection

Installation & Safety

1. Maintain minimum 3-meter clearance to earthed objects

2. Install in vertical orientation only

3. Ensure ambient temperature ≤40°C

4. Verify shield ring continuity before operation

5. Perform dielectric test after installation

Complies with IEC 60060-1 and IEEE 4 standards for high-voltage testing.
