S11 Series 10kV, 20kV Low Loss Power Transformers

Product introduction

This product adheres to the esteemed national standards of GB1094 "Power Transformer" and GB/T6451 "Three-phase oil-immersed power transformer technical parameters and requirements," ensuring top-tier quality and reliability.
The S11 series represents a pinnacle in three-phase oil-immersed distribution transformers. Crafted with precision, the core material includes superior DQ133-30 (type 9), 30ZH 120 (type 11), 23ZH90 (type 13), and other meticulously selected cold-rolled silicon steel sheets. Our commitment to excellence ensures that the core materials in use consistently exceed the pattern requirements, offering unparalleled performance.
Our product showcases an advanced fully sealed corrugated oil tank design. This innovative feature ensures the transformer oil is completely isolated from the surrounding air, preventing moisture absorption and maintaining impeccable insulation strength. Moreover, the exclusion of oxygen from the fuel tank mitigates insulation material aging, thereby enhancing the product's longevity and magnifying its societal benefits.

Product features

Energy Savings: The S11 type is engineered to significantly reduce power losses, achieving an average 30% reduction in no-load losses, a 25% reduction in load loss, and a 20% cut in operating costs compared to the GB/T6451 benchmarks, offering substantial energy and cost efficiencies.
Long service life: Employing a fully sealed transformer oil tank design, the construct allows for bolting or welding to securely enclose the fuel tank and box edges. This meticulous sealing prevents air contact, consequently prolonging the service life and reliability of the unit.
High operating reliability: Through strategic enhancements of the fuel tank seal components, we ensure heightened reliability, refining the process level to guarantee an impeccable and durable seal, thereby fortifying the unit's dependability.
Small footprint: The innovative S11-M series transformer tank employs a corrugated plate radiator design. This smart solution enables the corrugated plate to compensate for thermal expansion and contraction when oil temperature fluctuates, effectively replacing the oil conservator. This design not only optimizes functionality but also maintains avisually appealing aesthetic while minimizing spatial requirements.
