Ultra-High Insulation EMI Suppression for Critical Power Systems

Engineered for the most demanding industrial environments, the LQLVF 80kVA/2×200A Power Noise Filter delivers exceptional electromagnetic interference suppression with unmatched 6kV/1min insulation integrity. Featuring dual 100A circuits, ONAN cooling technology, and >70 reactor quality factor, this high-capacity solution provides >60dB attenuation across 40kHz-1MHz spectrum with zero abnormal discharge.

Technical Specifications

Performance Features

Ultra-High Insulation Integrity

6kV/1min dielectric strength with verified zero abnormal discharge - exceeds IEC 60664-1 requirements by 200%.

Premium Reactor Performance

Quality factor >70 ensures minimal energy loss (<0.25%) while maximizing noise absorption efficiency.

High-Frequency Attenuation

Superior noise suppression: >40dB (40-100kHz) and >60dB (100kHz-1MHz) across EMI spectrum.

Design Advantages

• Dual-Circuit Redundancy: Independent 100A channels for critical system protection

• Maintenance-Free ONAN Cooling: Natural oil convection for thermal stability at full load

• Symmetric Power Architecture: Identical 0.4kV input/output maintains voltage stability

• Industrial Robustness: Military-grade components rated for 100,000+ operational hours

Industrial Applications

• High-voltage industrial substations

• Power generation control systems

• Critical infrastructure protection

• Heavy manufacturing equipment

• Industrial process control centers

• High-power test facilities

Key Benefits

• Unmatched Insulation Safety: 6kV/1min rating with zero discharge verification

• High Power Density: 80kVA capacity in efficient ONAN-cooled package

• Broad-Spectrum Noise Control: Effective EMI suppression from 40kHz to 1MHz

• Energy Efficient: >98.8% power transfer efficiency at full load

Installation Guidelines

1. Thermal Management:

• Maintain 200mm top clearance for heat dissipation

• Maximum ambient temperature: 40°C

• Vertical mounting orientation required

2. Electrical Connections:

• Input/Output: 150mm² copper conductors

• Terminal torque: 70Nm

• Ground with 50mm² cable (resistance <0.1Ω)

3. Testing Protocol:

• Perform 6kV/1min AC hi-pot test (no abnormal discharge)

• Verify insulation resistance >2GΩ at 10kV DC

• Confirm attenuation with spectrum analyzer sweep

• Check oil dielectric strength >45kV (per IEC 60296)

Why This Filter Stands Out

• Industry-Leading Insulation: 6kV rating with verified zero discharge

• High Reactor Efficiency: >70 quality factor for minimal power loss

• Ultra-Reliable Design: ONAN cooling for 24/7 continuous operation

• Future-Proof Performance: Designed for 20+ year service life
