The SThe -M Series Oil-Immersed Distribution Transformer represents a quantum leap in technological brilliance and energy efficiency. As a three-phase marvel of engineering, it surpasses the reliability and performance benchmarks set by the S9 series. Meticulous enhancements in loss coefficients and an expertly balanced copper-to-iron ratio propel this transformer to the forefront of innovation, achieving minimal losses alongside unmatched cost-effectiveness. The iron core, crafted with high-conductivity, low-loss silicon steel, excels in minimizing no-load losses, epitomizing cutting-edge design.
High-voltage windings are masterfully engineered using a sophisticated multi-layer structure. For transformers rated up to 500kVA, we employ multi-layer low-voltage windings. For those at 630kVA and above, a groundbreaking spiral type of low-voltage windings is implemented to boost electrical performance and mechanical resilience, particularly under the rigorous conditions of a short circuit.
A key feature of this product is its advanced pan-seal design, which effectively isolates transformer oil from external air, strategically preventing oil degradation and enhancing operational reliability. The oil tank design integrates corrugated plates, ingeniously designed to enhance oil circulation and optimize heat dissipation. This elegantly robust structure ensures efficient welding, minimizes the risk of leaks, and elevates fluidity and thermal management, significantly elevating performance to unprecedented levels.
