The S13-M series 200kVA oil immersed distribution transformer represents an advanced, energy-efficient solution for modern 10kV to 0.4kV power networks. Designed to meet strict Tier 2 energy efficiency requirements, it significantly lowers long-term operational costs by reducing no-load losses by approximately 15% to 20% when compared to traditional S11-M models. The unit features a fully sealed (M-type) corrugated tank construction combined with 100% copper windings. This design prevents internal oil degradation, completely isolating the core from ambient air to guarantee a long, maintenance-free service life.
Manufactured with strict quality control, this transformer conforms to IEC 60076 and GB/T 6451 international standards, demonstrating top-tier manufacturing expertise. Below is the core datasheet for bulk procurement evaluation:
