Innovative Structural Design

Honeycomb Thermal Management

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

• Optimal air-thermal exchange for efficient cooling

• Prevention of resistance degradation under thermal stress

• Uniform temperature distribution across resistor body

• Material strength preservation at high temperatures

Triple-Shielding Ring Protection

Strategic shielding rings at both ends and center provide:

• Complete discharge path isolation during test failures

• Insulation damage prevention

• Electromagnetic interference (EMI) suppression

• Corona discharge minimization

Performance Features

• Thermal Stability: Maintains <100K temperature rise at 750kV/0.5A for 60 minutes

• Material Integrity: Nickel-chromium alloy ensures consistent resistance values at high temperatures

• Structural Reliability: Epoxy-wound construction withstands mechanical stress during transients

• Voltage Endurance: Certified performance at 750kV without flashover

Critical Applications

• Impulse voltage generator circuits

• Ultra-high-voltage transformer testing

• GIS (Gas-Insulated Switchgear) partial discharge measurement

• HVDC transmission system commissioning

• High-power laboratory test systems

Installation & Safety Protocols

1. Maintain minimum 3-meter clearance to grounded surfaces

2. Install exclusively in vertical orientation

3. Ensure ambient temperature ≤40°C during operation

4. Verify shield ring continuity before energizing

5. Perform dielectric verification test after installation

Complies with international standards: IEC 60060-1, IEEE 4, and IEC 60270.
