In today's demanding industrial and commercial electrical environments, achieving optimal energy efficiency and operational reliability is paramount. Our advanced 10kV low loss transformer range is engineered to meet these critical needs, delivering significant reductions in no-load and load losses compared to conventional designs. These substantial savings translate directly into lower operational costs and a reduced carbon footprint over the transformer's entire lifecycle. The core of our efficiency lies in the use of high-grade, cold-rolled, grain-oriented silicon steel for the magnetic core, minimizing hysteresis and eddy current losses. For applications requiring enhanced safety, environmental compatibility, and superior performance in challenging conditions, we offer our specialized low loss dry type transformer. This design is ideal for indoor installations, fire-sensitive areas, and locations with strict environmental regulations due to its air-cooled, non-flammable construction. A prime example of this capability is our robust 500kva 10kv dry type transformer, which offers a perfect balance of power, efficiency, and safety for medium-capacity applications in data centers, hospitals, high-rise buildings, and manufacturing plants.
The YSL-10 Series Low Loss Distribution Transformer is designed with a relentless focus on durability and performance stability. Its tank is constructed from high-quality steel with excellent anti-corrosion properties, ensuring long-term protection even in harsh environments. All external components, including bushings and conservators, are selected from internationally recognized brands to guarantee reliability. The transformer undergoes a rigorous vacuum oil-filling process, effectively eliminating moisture and air to prevent internal partial discharges and insulation degradation. Furthermore, the entire unit is subjected to a comprehensive pressure leak test to ensure absolute integrity. The windings are meticulously crafted using oxygen-free copper conductors, which offer lower resistivity and better thermal performance than aluminum, further contributing to the overall low-loss characteristics and overload capability of the YSL-10 Series.
