The SThe -M Series Oil-Immersed Distribution Transformer sets an unparalleled standard in cutting-edge technology and superior efficiency. This innovative three-phase masterpiece is designed to outshine the S9 series, offering unmatched reliability and exceptional performance. By meticulously refining loss coefficients and optimizing the copper-to-iron ratio, this transformer exhibits a design that remarkably minimizes losses while maximizing cost-effectiveness. The iron core is expertly crafted using high-conductivity, low-loss silicon steel, dramatically reducing no-load losses, and embodying the pinnacle of modern design innovation.
High-voltage windings are expertly constructed with a sophisticated multi-layer structure. For transformers up to 500kVA, our design incorporates multi-layer low-voltage windings; for those rated at 630kVA and above, an advanced spiral type of low-voltage windings significantly enhances both electrical performance and mechanical strength, particularly under the demanding conditions of a short circuit.
A defining feature of this product is its avant-garde pan-seal design, which flawlessly isolates transformer oil from external air, ingeniously preventing oil degradation and boosting operational reliability. The oil tank design beautifully integrates corrugated plates, artistically conceived to optimize oil circulation and enhance heat dissipation. This elegantly simplistic yet robust structure ensures efficient welding, minimizes the potential for leaks, and elevates fluidity and thermal management, significantly driving performance to extraordinary new heights.
