S13 Series Oil-immersed Transformer: Pinnacle of Engineering Innovation

The S13 series of Oil-Filled Transformer represents the pinnacle of engineering innovation, designed to meet the evolving demands of modern power distribution. Crafted with the finest cold-rolled grain-oriented silicon steel sheets, this series employs an even more rigorous core manufacturing process that sets new standards for material quality and precision.

Key Features:

• Superior Core Material: The S13 series utilizes the highest-grade cold-rolled grain-oriented silicon steel sheets, ensuring a core with exceptional magnetic properties and minimal energy loss.
• Advanced Manufacturing Process: The stringent core fabrication techniques demand the highest standards for core materials and cutting equipment, reflecting a commitment to quality and performance.
• Enhanced Energy Efficiency: Compared to previous standards, the S13 series achieves a 25% reduction in no-load losses and an 80% reduction in no-load current, significantly improving operational efficiency.
• Noise Reduction: The innovative design and materials used in the S13 series result in a notable reduction in noise levels by 5-10dB, contributing to a quieter and more environmentally friendly operation.

Technical Specifications:

Core Design:

The Oil Immersed Distribution Transformer feature a high-permeability, low-loss core with a unique lamination structure that minimizes magnetic flux density distortion, leading to substantial reductions in no-load losses and currents.

Low Voltage Winding:

The low voltage winding is designed with a compact foil winding method, which not only reduces the physical footprint but also minimizes radial forces during short circuits, enhancing the transformer's resilience against sudden short-circuit events.

Sealed Tank Construction:

The transformers incorporate a corrugated oil tank design that prevents contact between atmospheric air, moisture, and transformer oil, thus reducing oil aging and extending the transformer's operational lifespan. The corrugated plates are engineered to accommodate the thermal expansion and contraction of the oil.

Outdoor Configuration:

These transformers are designed for outdoor use, featuring high pollution resistance and efficient heat dissipation, ensuring maintenance-free operation over their service life and contributing to the secure and reliable operation of the power grid.

Safety Mechanisms:

Equipped with a pressure relief safety mechanism that effectively vents excessive pressure in the event of a transformer malfunction, preventing potential escalation of incidents.
