The SThe -M Series Oil-Immersed Distribution Transformer is a groundbreaking marvel in the realm of technological excellence and efficiency. This three-phase innovation is expertly designed to surpass the capabilities of the S9 series, delivering unmatched reliability and extraordinary performance. By meticulously refining loss coefficients and optimizing the copper-to-iron ratio, this transformer embodies a sophisticated design that significantly reduces losses while ensuring economic efficiency. The iron core is masterfully crafted with high-conductivity, low-loss silicon steel, dramatically reducing no-load losses and establishing a benchmark of cutting-edge design ingenuity.
High-voltage windings are meticulously engineered with a sophisticated multi-layer structure. For transformers up to 500kVA, we incorporate advanced multi-layer low-voltage windings, while for those rated at 630kVA and greater, a revolutionary spiral type of low-voltage windings is employed, enhancing electrical performance and mechanical resilience, particularly under the rigorous conditions of a short circuit.
A distinguishing feature of this product is its cutting-edge pan-seal design, which adeptly isolates transformer oil from external air, ingeniously preventing oil degradation and bolstering operational dependability. The oil tank design includes corrugated plates, expertly crafted to enhance oil circulation and maximize heat dissipation. This elegantly straightforward yet sturdy structure guarantees efficient welding, reduces the risk of leaks, and elevates fluidity and thermal management, significantly boosting performance to unparalleled heights.
