Precision Power Isolation for Critical Systems

Designed for high-noise environments, this oil-immersed isolation transformer features dual electrostatic shields that reduce electromagnetic interference (EMI) by up to 45dB. The specialized shielding between HV/LV windings and coil assemblies effectively minimizes partial discharge interference in sensitive measurement systems, ensuring signal integrity for precision instruments.

Technical Specifications

Core Engineering Features

Dual Electrostatic Shielding

Copper-foil barriers between HV-LV and LV-coil assemblies create a Faraday cage effect, attenuating common-mode noise >40dB in the 10kHz-1MHz range critical for partial discharge measurements.

Optimized Impedance Design

Precisely calibrated 8% impedance voltage provides optimal balance: limits fault currents while maintaining voltage stability during 30-100% load fluctuations.

Oil-Immersed Construction

Mineral oil cooling enables continuous full-load operation with maximum 50°C temperature rise, 35% more efficient heat dissipation than dry-type transformers.

Industrial Applications

• High-Voltage Test Facilities: Isolate PD measurement equipment from grid disturbances

• Industrial Automation: Clean power for PLCs and servo drives in manufacturing

• Renewable Energy Systems: Stabilize output in solar/wind converter stations

• Laboratory Instrumentation: Noise-free supply for precision measurement devices

Safety & Compliance

• Overload Protection: Thermal cutoffs trigger at 85°C (IEC 60076-11 compliant)

• Environmental Protection: IP54-rated enclosure resists dust and moisture ingress

• Safety Standards: Meets IEC 61558-2-4 for isolation transformers

• Pressure Management: Diaphragm pressure-relief valve prevents oil tank overpressure
