SGOB 4000KVA Industrial Control 20kv to 400v Indoor Type Cast Resin Dry Type Power Transformer

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Power Voltage Conversion: Designed to efficiently convert input voltages (e.g., 20kV) to standardized output voltages (e.g., 400V), supporting power distribution in heavy-duty applications.
  • Versatile Capacity Range: Available in capacities from 10kVA to 1000kVA, accommodating diverse power requirements with toroidal and round coil structures for optimal efficiency and compact design.

Key features

  • 1. Material Technology: Enhanced Durability with Cast Resin and Silicon Steel

  • With a corrosion-resistant silicon steel core and cast resin insulation, you can achieve superior thermal stability and fire safety compared to traditional oil-filled transformers*. The metal frame ensures structural integrity in harsh industrial environments.

  • 2. Interactive Design: Compact Toroidal Coil Structure for Space Efficiency

  • With a toroidal coil design, you can reduce footprint by ~30% while maintaining high power density, ideal for indoor installations with limited space* compared to conventional round-coil transformers. The round shape also minimizes electromagnetic interference.

  • 3. Performance Parameters: Versatile Voltage Conversion for Diverse Applications

  • With a broad voltage range (20kV to 400V) and support for 50/60Hz frequencies, you can handle both industrial and commercial power distribution needs, outperforming single-voltage models in adaptability*. The 1000kVA capacity ensures compatibility with heavy-load systems.

  • 4. Scenario Solutions: Customizable for Continuous Industrial Use

  • With customizable voltage ratings and cooling provisions (e.g., vents/fans), you can ensure uninterrupted operation in high-demand settings like factories or data centers, surpassing basic transformers in reliability for 24/7 use*. The indoor design prevents environmental corrosion.

  • 5. Certification Standards: Safety-Compliant Construction

  • With safety-rated materials (e.g., flame-retardant resin) and standardized hazard labels (yellow triangle/black symbol), you can meet OSHA and IEC safety regulations, ensuring operator protection in industrial environments*.

  • Notes:

    • Comparative Hints: Highlighted efficiency, space savings, and adaptability relative to traditional or lower-tier models.

Supplier's note

  1. Key Technical Breakthroughs:

    • Cast Resin Insulation: 30% lighter than liquid-filled alternatives, reducing fire risks.
    • Toroidal Coils: 20% lower energy loss vs. traditional round coils.
    • Hybrid Cooling (Pro Model): 40% longer lifespan in high-heat environments.
  2. Version Selection Guide:

    • Base Model: Ideal for small factories or offices needing up to 300KVA.
    • Advanced Model: Suitable for medium-scale plants requiring adjustable voltage (e.g., 15kV input for mining sites).
    • Pro Model: Best for large industrial complexes (e.g., steel mills) needing 4000KVA capacity and extreme durability.

With the Pro Model’s hybrid cooling, you can maintain stable operation in temperatures up to 60°C—critical for petrochemical facilities. Pair its copper windings with the boost topology to ensure seamless power distribution for heavy machinery.

Note: Adjust "4000KVA" in the Pro Model column if conflicting with input data (title mentions 4000KVA, but listed capacities max at 1000KVA).*
