The SThe -M Series Oil-Immersed Distribution Transformer revolutionizes the industry with its unparalleled technological advancement and efficiency. This state-of-the-art three-phase transformer is meticulously engineered to exceed the S9 series, setting new standards in reliability and exceptional performance. By meticulously refining loss coefficients and optimizing the copper-to-iron ratio, this transformer boasts a design that dramatically reduces losses while enhancing cost-efficiency. The iron core is skillfully crafted from high-conductivity, low-loss silicon steel, drastically minimizing no-load losses and epitomizing the pinnacle of innovative design.
The high-voltage windings are precisely crafted with a complex multi-layer structure. For transformers rated up to 500kVA, we utilize multi-layer low-voltage windings. For those rated at 630kVA and above, we incorporate an innovative spiral type of low-voltage windings, which significantly enhance both electrical performance and mechanical strength, especially under the demanding conditions of a short circuit.
A standout feature of this product is its cutting-edge pan-seal design, which effectively isolates the transformer oil from external air, cleverly preventing oil degradation and amplifying operational reliability. The oil tank design features corrugated plates, which are gracefully designed to improve oil circulation and maximize heat dissipation. This elegantly simple yet robust structure ensures efficient welding, minimizes the risk of leaks, and enhances fluidity and thermal management, markedly boosting performance to unprecedented levels.
