Technical Specifications

Design Advantages

• Compact Form Factor: 30% smaller footprint than comparable 300kV resistors

• High Power Density: 62.5 W/kg efficiency rating

• Optimized Thermal Management: Natural convection cooling with finned surface design

• Low-Inductance Construction: <5μH for transient stability

• Corona-Free Operation: Rounded edges and smooth surfaces prevent discharge

Typical Applications

HV Test Circuits

Current limiting in 300kV withstand test setups and partial discharge measurement systems

Power System Protection

Series protection for capacitor banks and transformer bushings

Research Facilities

Wavefront shaping in impulse voltage generators and HV divider networks

Installation & Mounting

1. Mount on insulated platforms (minimum 150mm creepage distance)

2. Maintain ≥1.2m clearance to grounded surfaces (per IEC 61958)

3. Use M12 terminal connectors with 25Nm torque specification

4. Ensure vertical orientation for optimal thermal performance

Note: Base mounting points provided for 16mm anchor bolts
