The SThe -M Series Oil-Immersed Distribution Transformer is a groundbreaking marvel in the realm of technology and efficiency. This innovative three-phase design is not only a testament to engineering excellence but also surpasses the renowned S9 series with its superior reliability and exceptional performance. Through meticulous enhancement of loss coefficients and a masterfully optimized copper-to-iron ratio, this transformer emerges as a modern marvel, reducing losses while being cost-efficient. The iron core, crafted with precision using high-conductivity, low-loss silicon steel, dramatically curtails no-load losses, epitomizing cutting-edge design at its finest.
High-voltage windings are expertly designed with a sophisticated multi-layer structure. In transformers up to 500kVA, we incorporate precision-engineered multi-layer low-voltage windings. For those rated at 630kVA and beyond, a transformative spiral type of low-voltage windings is introduced, enhancing electrical performance and bolstering mechanical strength, especially under the rigorous demands of a short circuit.
A defining feature of this exceptional product is its advanced pan-seal design, ingeniously separating transformer oil from external air, effectively preventing oil degradation and boosting operational reliability. The oil tank design incorporates elegantly crafted corrugated plates, designed to optimize oil circulation and maximize heat dissipation. This elegantly simplistic yet robust construction ensures seamless welding, minimizes the risk of leaks, and elevates fluid dynamics and thermal management, pushing performance boundaries to unparalleled heights.
