Our oil immersed distribution transformer is designed for urban power grids, residential districts, industrial plants and box-type substation projects. Adopting high-quality cold-rolled silicon steel sheet and corrugated fully sealed tank structure, this transformer achieves ultra-low no-load loss, low noise and stable heat dissipation performance.
We provide a full power range from 10kVA to 2500kVA, supporting 10kV input voltage and customized tap adjustment. The insulating oil completely isolates the winding from air, effectively preventing moisture and oxidation, greatly extending service life with zero maintenance within 10 years.
All our oil immersed transformers have passed IEC, ISO and local power grid certification. We support OEM & ODM customization on capacity, voltage ratio, protection accessories and paint color. Suitable for overhead line pole mounting, underground box substation and factory indoor power distribution systems.
Complies with GB1094 & GB/T6451 national standards, fully certified for power grid application Full copper winding design with upgraded core materials, drastically cutting no-load & load losses Adopts brand-new insulation materials and precision production processes for better energy efficiency Optimized internal coil structure delivers stable operation.
Product Description
Superior Economic & Energy-Saving Benefits Developed as an upgraded generation based on traditional S9 distribution transformers, S11~S13 models deliver remarkable energy efficiency gains. Compared to S9 type units, average no-load power loss cuts down by 30%, while idle excitation current drops sharply by 70%–85%. This slashes long-term power consumption and operational expenditure for users.
Extended Overall Service Lifespan
The transformer tank features a fully hermetic sealed design. The tank body and flange edge can be assembled via bolt fastening or full fusion welding. This air-isolated structure completely prevents transformer insulating oil from direct exposure to oxygen and moisture in the atmosphere, slowing oil aging and insulation degradation to greatly prolong the equipment’s usable life. Stable & Trustworthy Running Performance We upgraded the sealing structural components of the oil tank with optimized structural design and refined manufacturing techniques. The enhanced sealing construction eliminates leakage risks effectively, delivering consistent tightness and stable performance throughout long-term continuous operation. Compact Footprint & Streamlined Outline S11-M and S13-M transformers are fitted with integrated corrugated cooling radiators on the tank wall. The corrugated sheets expand and contract automatically following temperature fluctuations of internal insulating oil, taking over the pressure compensation function that traditional conservator tanks provide. Without an extra oil storage tank, the unit features a neat, compact exterior and requires much less installation space.
