Transformador de aceite mineral de alta eficiencia de 10 kV

Reliable Structural Design

• Spiral windings with longitudinal oil channels for enhanced internal heat dissipation.
• Reinforced support at winding ends for increased short-circuit resistance.
• New lifting and positioning structures ensure safe long-distance transport and stable operation.
• Multiple proprietary structural designs deliver higher reliability and performance.
• Advanced engineering ensures superior technological performance across all models.

Premium Material Selection

• Oxygen-free copper wire with low resistivity and smooth, burr-free surface treatment reduces load loss and improves electrical reliability.
• High-quality silicon steel sheets with low unit loss minimize no-load loss.
• Laminated wood insulation components remain intact even under short-circuit conditions.
• Deep-filtered transformer oil with minimal water, gas, and impurity content.
• Durable rubber seals effectively prevent aging and oil leakage.
• All materials undergo strict quality inspection and supplier audits in compliance with ISO9001 standards.

Enhanced Technical & Economic Performance

• Compared to the S9 series, the S11 series offers:
  • 30% reduction in average no-load loss
  • 70–85% lower no-load current
  • 10K lower average temperature rise
  • Over double the service life
  • Capable of continuous 20% overload operation
  • 2–4 dB lower operating noise

Fully Sealed Construction

• The “M” in model S11(METRO)R denotes a fully sealed tank design.
• Replaces conventional oil pipes with corrugated fins for heat dissipation, eliminating the need for an external oil conservator.
• Welded corrugated fins, made from high-quality cold-rolled steel, allow oil volume expansion while isolating the interior from the atmosphere.
• This design slows oil aging and prevents moisture absorption, ensuring maintenance-free operation.
• The tank undergoes degreasing, derusting, phosphating, and triple-protection coating, making it suitable for harsh environments such as metallurgical, petroquímico, and mining applications.
