Industrial Grade Efficiency
& Advanced Power Isolation

Optimizing voltage conversion for critical industrial machinery with surgical precision.

Our 380V to 200V Three Phase Isolation Transformer stands as a benchmark in electrical engineering, specifically developed to bridge the gap between standard 380V industrial grids and sensitive 200V equipment. By integrating high-grade silicon steel cores and oxygen-free copper windings, our units eliminate common-mode noise and provide a clean, isolated power path that significantly extends the lifespan of downstream electronics.

Beyond simple conversion, these transformers utilize advanced electromagnetic insulation to prevent electrical faults from propagating across the system. This technical superiority ensures that your facility maintains Total Harmonic Distortion (THD) below 3%, delivering an ultra-stable energy flow even in the most volatile industrial electrical environments.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries regarding our isolation systems.

01

Why is a 380V to 200V isolation transformer better than an autotransformer?

Unlike autotransformers, our 380V to 200V Three Phase Isolation Transformer provides complete galvanic separation. This means there is no direct electrical connection between the primary and secondary circuits, effectively blocking DC offsets and protecting equipment from catastrophic surge propagation.

02

How do you ensure the 200V output remains stable under varying loads?

We utilize high-permeability silicon steel and oversized copper windings to minimize voltage drop (impedance) during peak load. This ensures that the output remains within a strict ±2% tolerance regardless of the load factor.

03

Can these transformers be installed in outdoor environments?

Yes, we offer specifically engineered outdoor variants with IP65-rated sealed enclosures and advanced oil-cooling systems to prevent moisture and dust ingress, suitable for all climatic zones.

04

What is the typical lead time for a custom kVA specification?

Standard units are typically shipped within 7-14 days. For custom kVA ratings or specialized enclosure requirements, the lead time is generally 3-5 weeks, including full factory acceptance testing (FAT).

05

How does the transformer reduce harmonic distortion?

By utilizing a specific winding geometry and high-grade core materials, the transformer acts as a low-pass filter, significantly attenuating high-frequency noise and lowering THD for downstream power electronics.

06

What maintenance is required for the oil-cooled models?

Our fully sealed designs are nearly maintenance-free. We recommend a simple visual inspection of oil levels and terminal tightness every 12 months to ensure optimal performance.
