Product Description

 

Product Description

 
The S -M Series Oil-Immersed Distribution Transformer is a state-of-the-art, three phase transformer developed to enhance reliability and performance over the S9 series.By refining loss coefficients and optimizing the copper-to-iron ratio, it achieves superior loss design and cost-effectiveness. The iron core utilizes high-conductivity, low-loss silicon steel, minimizing no-load losses.

    For high-voltage windings, a multi-layer structure is employed, with products up to 500kVA featuring multi-layer low-voltage windings. For transformers of 630kVA and above, a new spiral type for low-voltage windings is used, improving electrical performance and mechanical strength, especially during short circuits.
 

    A key feature is its pan-seal structure, which isolates the transformer oil from external air, preventing oil aging and enhancing operational reliability. The oil tank design uses corrugated plates to facilitate oil circulation and improve heat dissipation. This simple yet robust design ensures efficient welding, reduces the likelihood of leaks, and optimizes fluidity and thermal management.
