The SThe -M Series Oil-Immersed Distribution Transformer is a groundbreaking innovation, setting an entirely new benchmark in advanced technology and unmatched efficiency. This three-phase marvel surpasses the S9 series, delivering exceptional reliability and extraordinary performance. With precise enhancement of loss coefficients and a meticulous optimization of the copper-to-iron ratio, this transformer is a masterpiece of design, minimizing energy losses while ensuring cost-effectiveness. The iron core, crafted with high-conductivity, low-loss silicon steel, drastically reduces no-load losses, embodying the zenith of cutting-edge design.
The high-voltage windings are expertly designed with a sophisticated multi-layer structure. For transformers up to 500kVA, our design incorporates advanced multi-layer low-voltage windings. For units rated at 630kVA and above, we introduce a groundbreaking spiral type of low-voltage windings, significantly enhancing electrical performance and mechanical resilience, particularly under the rigorous conditions of a short circuit.
A defining feature of this product is its cutting-edge pan-seal design, which ingeniously isolates transformer oil from external air, effectively preventing oil degradation and boosting operational reliability. The oil tank design is complemented by sophisticated corrugated plates, meticulously engineered to optimize oil circulation and maximize heat dissipation. This elegantly simple yet robust structure ensures flawless welding, minimizes leakage risks, and enhances fluid dynamics and thermal management, propelling performance to unparalleled heights.
