Inductance Comparison

Military-Grade Construction

Robust Mechanical Design

• Segmented air-gap iron core with oxygen-free copper windings

• Iron-shell oil tank provides:

• 35% better heat dissipation vs epoxy designs

• Enhanced mechanical protection during transport

• Integrated breather capsule with humidity indicator

Transport Optimization

• Vibration-tested per IEC 61373 Category 1 for:

• 2000km railway transport

1000km highway movement

• 260kV-rated lifting hooks with load sensors

• Corner impact protection for rough terrain

Application Excellence

• Subsea Cable Testing: 22Hz very low frequency verification

• EHV Transformer Tests: 500kV class routine testing

• Offshore Wind Farms: Array cable commissioning

• GIS Partial Discharge: Ultra-clean measurements

Why This System Stands Out

1. Dual-Inductance Flexibility: Optimize for both cables and transformers

2. Unmatched Q Factor: 20% more efficient than competitors at 22Hz

3. Field-Ready Durability: -25°C to +50°C operational range
