S13 Dry Type Sealed Three Phase Oil Immersed Transformer Distribution Low Loss Power Isolation 10kv AC Outdoor

S13 Dry Type Sealed Three Phase Oil Immersed Transformer Distribution Low Loss Power Isolation 10kv AC Outdoor. Fully Sealed Structure: Eliminates oil tanks, prevents air contact to slow oil degradation and insulation aging. Low Loss & High Efficiency: Uses imported cold-rolled silicon steel to significantly reduce no-load losses and currents. Low Noise Design: Tied iron core and optimized structure ensure noise levels lower than standard requirements. Maintenance-Free Operation: Fully sealed design extends service life and eliminates the need for lifting and maintenance. High Quality Windings: High/low voltage windings made of oxygen-free copper for superior conductivity and durability. Harmonic Reduction: Dyn11 connection group reduces harmonic impact on the power grid and improves power quality. 100% Quality Control: Over 10 QC inspections during manufacturing; every unit has 3C certificate and 100% final inspection. Customization Available: Supports customization for winding material, input voltage, rated capacity, and coil material.
